IlvStyleSheetRenderer (Rogue Wave JViews 9.1 API)

java.lang.Object
- ilog.views.sdm.renderer.IlvSDMRenderer
- - ilog.views.sdm.renderer.IlvStyleSheetRenderer

All Implemented Interfaces:

IlvStylable, Serializable

Direct Known Subclasses:

IlvMapStyleSheetRenderer, IlvMapStyleSheetRenderer
```
public class IlvStyleSheetRenderer
extends IlvSDMRenderer
implements IlvStylable
```
This class manages a CSS renderer. Basically it contains all the necessary code to create and customize graphic objects, given an SDM model and a style sheet. Although the class is intended to be used under the SDM framework, it provides the low-level methods to create and customize any bean.
Note that the full hierarchy under the root node must be available (no delayed load).
Reaction to property changes means rematching the rules against the root node, and then applying graphic attributes to all nodes.
Nodes and links are instantiated from a class name specified by the declaration "class". Instances may also be created by factory, prototypes, and Java serialized beans (see createNodeInstance(ilog.views.sdm.IlvSDMEngine, java.lang.Object, java.util.Map) for more details).
IlvStyleSheetRenderer defines the following renderer graphic properties: x, y, width, height, Anchor, Layer. The first five are ignored for links. "Anchor" means the object bounding box anchor, as defined in IlvConstants (for example, TOPLEFT, CENTER). "Layer" is the insertion layer for nodes and link.
The "toolTipText" property can be used to set the tooltip of any node or link.
Pseudoclasses of IlvStyleSheetRenderer are "renderer" and "styleSheetRenderer". Here is an example of a rule that matches only this renderer:
```
 node:styleSheetRenderer { Anchor : Center; } 
 
```
The way CSS declarations are applied to IlvGraphics is explained in customize(ilog.views.sdm.IlvSDMEngine, java.lang.Object, ilog.views.IlvGraphic, java.lang.String[]).
To match CSS rules:
CSS type is "node" or "link", according to the model predicate isLink(),
CSS ID matches getID() on nodes,
CSS class matches node getTag() or property "CSSclass" on node (customizable). CSS classes must be " " separated.
CSS Attribute matches property of same name on node.
CSS Pseudoclasses match renderer pseudoclasses (in getGraphicProperty()).
Note concerning the base URL: The style sheet manages its own base URL, which is updated while resolving import statements. The starting base URL is deduced by the style sheet references in the array given to setStyleSheets(String[]), or is fixed by the constructor. Base URL is needed to resolve the right-hand part of declarations like "prop : url(relative-path);"

    Specifies whether restyling operations are optimized, taking into account the model properties which are referenced in the CSS rules for the particular objects and the model properties which have actually changed on the particular objects. This is an advanced optimization based on memoization. It is enabled by default. You might need to turn it off when there are hidden dependencies among property values in a model object, that are not reflected by the IlvMutableSDMNode.getDependentProperties(String) method.
    This method can only be called before any IlvDiagrammer or IlvSDMEngine has been created. It must not be called when styling is already in use.

  - setBaseTextDirection
```
public void setBaseTextDirection(int baseTextDirection)
```
    Changes the global base direction of the text. This affects all text that inherits the base text direction from the top level grapher of the SDM engine. Graphic objects that have a specific base text direction that is not inherited are not affected. The possible choices are:
    - IlvBidiUtil.COMPONENT_DIRECTION: the base text direction is calculated from the component orientation.
    - IlvBidiUtil.LEFT_TO_RIGHT: the base text direction is left-to-right.
    - IlvBidiUtil.RIGHT_TO_LEFT: the base text direction is right-to-left.
    - IlvBidiUtil.CONTEXTUAL_DIRECTION: the base test direction is determined from the text that is displayed according to the standard Bidi algorithm, if the text contains at least one character with a strong left-to-right or right-to-left direction. If the text doesn't contain any character with a strong direction, the real text direction is determined from the current component orientation of the object.
    Note: if you never specify the base text direction on the SDM engine directly, then this value specified here is taken into account. When you set the base text direction on the SDM Engine directly, you can use IlvSDMEngine.setBaseTextDirection(int, boolean) to specify whether the value from the style sheet renderer should be ignored or not.
    Parameters:
    
    baseTextDirection - The base text direction

    Sets whether a link connector is added on the nodes to compute the link connection points. Default is true, and a IlvSDMLinkConnector is added on nodes. The connector class can be overriden by the "LinkConnector" renderer property.
    
    Parameters:
    
    add - true to add link connectors

```
public int getLinkConnectorMode()
```
    Returns the link connector mode. The link connector mode is only relevant if adding link connectors is enabled via setAddingLinkConnectors(boolean).
    
    Since:
    
    JViews 8.1
  - setLinkConnectorMode
```
public void setLinkConnectorMode(int mode)
```
    Sets the link connector mode. Possible modes are:
    - CENTER - Link connector mode: Use IlvSDMLinkConnector for all nodes. The links will be connected to the center of the rectangle returned by getLinkConnectionRectangle(ilog.views.sdm.IlvSDMEngine, ilog.views.IlvGraphic, ilog.views.IlvTransformer, ilog.views.IlvLinkConnector).
    - FREE - Link connector mode: Use IlvSDMFreeLinkConnector for all nodes. The links will be connected to the border of the rectangle returned by getLinkConnectionRectangle(ilog.views.sdm.IlvSDMEngine, ilog.views.IlvGraphic, ilog.views.IlvTransformer, ilog.views.IlvLinkConnector).
    - CLIP - Use IlvSDMClippingLinkConnector for all nodes. The links will point to the the rectangle returned by getLinkConnectionRectangle(ilog.views.sdm.IlvSDMEngine, ilog.views.IlvGraphic, ilog.views.IlvTransformer, ilog.views.IlvLinkConnector) but end on the outline of the shape of the node. How the outline of a node is calculated depends on the implementation of IlvGraphic.getIntersectionWithOutline(ilog.views.IlvPoint, ilog.views.IlvPoint, ilog.views.IlvTransformer).
    You can also choose not to set the link connector at all by calling setAddingLinkConnectors(false). In that case, the links will be connected to the edges of the node's bounding rectangle (and the rectangle returned by getLinkConnectionRectangle(ilog.views.sdm.IlvSDMEngine, ilog.views.IlvGraphic, ilog.views.IlvTransformer, ilog.views.IlvLinkConnector) will be ignored).

  - isLinkConnectorEnabled
```
@Deprecated
public boolean isLinkConnectorEnabled()
```
    Deprecated. Since JViews 8.1, use getLinkConnectorMode().
    
    Returns true if the link connector that computes the connection points of links is enabled.
    
    Returns:
    
    true if link connector is enabled

  - setLinkConnectorEnabled
```
@Deprecated
public void setLinkConnectorEnabled(boolean enabled)
```
    Deprecated. Since JViews 8.1, use setLinkConnectorMode(int).
    
    Sets whether the link connector that computes the connection points of links is enabled.
    If the connector is enabled, it corresponds either to the FREE mode or to the CLIP mode, depending on the setting of setLinkConnectorMode(int).
    If the connector is disabled, it corresponds to the CENTER mode of setLinkConnectorMode(int).
    You can also choose not to set the link connector at all by calling setAddingLinkConnectors(false). In that case, the links will be connected to the edges of the node's bounding rectangle (and the rectangle returned by getLinkConnectionRectangle(ilog.views.sdm.IlvSDMEngine, ilog.views.IlvGraphic, ilog.views.IlvTransformer, ilog.views.IlvLinkConnector) will be ignored).
    
    Parameters:
    
    enabled - true to enable the link connector.

public IlvGraphic createNodeGraphic(IlvSDMEngine engine,
                                    Object node)
```
    Creates an IlvGraphic object that represents an SDM node, customizes it, and sets its location. It does not, however, add the graphic object to the grapher.
    This method calls the protected method createNode(ilog.views.sdm.IlvSDMEngine, java.lang.Object), and tries to set a location on the created IlvGraphic.
    
    Specified by:
    
    createNodeGraphic in class IlvSDMRenderer
    
    Parameters:
    
    engine - The SDM engine associated with the grapher in which the graphic object will be added.

```
    Returns a rectangle on which the connection points of the links to/from a node should be located. This method is either called from the link connector, which is passed as argument, or from the renderers with null as link connector argument.
    This basic implementation returns the bounding box of the node. It should be overridden by subclasses if the nodes contain text labels and/or decoration icons.
    
    Overrides:
    
    getLinkConnectionRectangle in class IlvSDMRenderer
    
    Parameters:
    
    engine - The SDM engine.

                              boolean redraw)
```
    Removes a graphic object representing a link of the SDM data model from the grapher.
    This method is called when a link is removed from the data model, or when a new graphic object must be created because of a state change, but not when the grapher is cleaned up before loading a new data model or a new style sheet. In such a case, the removeAll(ilog.views.sdm.IlvSDMEngine) method is called to cleanup the renderer's internal state if needed, and all the graphic objects are removed from the grapher all at once by the SDM engine.
    The default implementation simply calls IlvGrapher.removeLink(ilog.views.IlvLinkImage, boolean).
    
    Overrides:
    
    removeLinkGraphic in class IlvSDMRenderer
    
    Parameters:
    
    engine - The SDM engine associated with the grapher from which the graphic object will be removed.
    
    link - The link that has been removed or modified in the data model.
    
    graphic - The graphic object that must be removed from the grapher.

                              boolean redraw)
```
    Removes a graphic object representing a node of the SDM data model from the grapher.
    This method is called when a node is removed from the data model, or when a new graphic object must be created because of a state change, but not when the grapher is cleaned up before loading a new data model or a new style sheet. In such a case, the removeAll(ilog.views.sdm.IlvSDMEngine) method is called to cleanup the renderer's internal state if needed, and all the graphic objects are removed from the grapher all at once by the SDM engine.
    The default implementation simply calls IlvGrapher.removeNode(ilog.views.IlvGraphic, boolean).
    
    Overrides:
    
    removeNodeGraphic in class IlvSDMRenderer
    
    Parameters:
    
    engine - The SDM engine associated with the grapher from which the graphic object will be removed.
    
    node - The node that has been removed or modified in the data model.

  - prepareRendering
```
public void prepareRendering(IlvSDMEngine engine)
```
    This method is called when the SDM engine starts rendering a new SDM, before any createNodeGraphics or createLinkGraphics are called.
    
    Overrides:
    
    prepareRendering in class IlvSDMRenderer
    
    Parameters:
    
    engine - The SDM engine.
  - customize
```
public void customize(IlvSDMEngine engine,
                      Object node,
                      IlvGraphic g,
                      String[] pseudoClass)
```
    Sets the properties of a graphic object that represents a data object.
    This method finds out the declaration associated with the node, and uses bean introspection to set IlvGraphic property values. If the IlvGraphic is a prototype, the usual prototype setter is used.
    The method will deploy its best effort (that is, use PropertyEditor's setAsText()) to convert the value into a suitable type for the bean.
    Prefix with '@' the right-hand side of the declaration to get the value from the model object (or its ascendant in order, if it is null), instead of a direct literal. Special names @__ID and @__TAG refer to getID() and getTag() of the model.
    Prefix with '@#' the right-hand side of the declaration to recurse in the style sheet. The text after '@#' adds a dummy model object in an empty model whose ID is the text. It should match a rule in the style sheet whose declarations eventually create a bean. The bean will be customized before being assigned to the left-hand side property. The dummy node forwards model property requests to the source model object that contains the '@#'. This means that '@' constructions in '@#' rules refer to the '@#' originator.
    Prefix with '@+' (e.g.: "@+name") the right-hand side of the declaration to recurse in the style sheet like the '@#' construct, except that the object is created if and only if the property defined by the left hand has a null value, or contains an object which class name is different that the one defined in #name declarations. In this case the object is created, customized, and assigned to the property through the property setter, like with '@#'. Otherwise, the previous value is only customized according to the CSS declarations. In all cases, the setter is invoked. This construction spares object creations, since the '@#' may create a new bean upon each property change on the source model object.
    Prefix with '@=' the right-hand side of the declaration to recurse in the style sheet like the '@#' construct, except that the resulting object is shared. It is computed only the first time it is needed and stored in an internal table for all subsequent uses. The table is cleared when a new style sheet is set (that is, one of the setStyleSheets() methods is called).
    Prefix with '@|' the right-hand side of the declaration to invoke an function. The function can have a comma-separated list of arguments which are literals or other @-constructs, except another function. For example: label : '@|concat("name :",@name)';. See IlvSDMCSSFunction.
    If the right-hand side is the string "@", it means the property setting is cancelled. This operator simplifies the writing of the style sheet because it avoids negating CSS rule selectors. Example:
```
 node {
    color : orange;
 }
 node[kind = "ghost"] {
    color : @ ;
 }
 
```
    is equivalent to
```
 node[kind ~ "ghost"] {   // ~ means "different" for strings.
    color : orange;
 }
 
```
    Overrides:
    
    customize in class IlvSDMRenderer
    
    Parameters:
    
    engine - The SDM engine.
    
    node - The data object used to compute the graphic properties to set.
    
    g - The graphic object to customize.
    
    pseudoClass - A list of symbolic names that identify the context in which the graphic object must be customized. For example, the pseudo class defines the "pseudo-classes" in the style sheet renderer.

```
    Creates a node instance, according to the model and the style sheet declarations. The default behavior retrieves the "class" attribute from the CSS, loads the class from this name with the system class loader, and returns a new instance of this class using the constructor with an empty argument list.
    If the class name contains '#', the remainder of the name is a prototype URL. This method will then load the prototype and return an IlvGraphicGroup instance.
    If the class implements IlvRectangularObjectFactory, a declaration IlvRect is searched for to provide the factory's createObject() method with the initial rectangle.
    The exceptions that may be thrown are explained in Class.forName(java.lang.String) and Class.newInstance().
    
    Parameters:
    
    engine - The SDM engine associated with the grapher in which the graphic object will be added.
    
    node - The model object.
    
    decls - Hashtable of matched declarations from the CSS.
    
    Returns:
    
    the created node
    
    Throws:
    
    ClassNotFoundException
    
    InstantiationException
    
    IllegalAccessException

  - createNode
```
protected IlvGraphic createNode(IlvSDMEngine engine,
                                Object node)
```
    This method is called by the addNode method. It tries to create an instance of IlvGraphic to render the specified node, and sets properties according the CSS specifications.
    This method does not add the graphic object to the grapher.
    
    Parameters:
    
    engine - The SDM engine associated with the grapher in which the graphic object will be added.
    
    node - The model object.
    
    Returns:
    
    The graphic object mapped from the model object.

```
    Creates a link instance, according to the model and the style sheet declarations. The default behavior retrieves the "class" attribute from the CSS, loads the class from this name with the system class loader, and returns a new instance of this class using the constructor with two IlvGraphics and a boolean (oriented property, false) as arguments.
    The exceptions that may be thrown are explained in Class, methods forName(), getDeclaredConstructor(), and newInstance().
    
    Parameters:
    
    engine - The SDM engine associated with the grapher in which the graphic object will be added.
    
    node - The model object.
