Class IltLinkLayoutLinkProperty

java.lang.Object

ilog.views.IlvNamedProperty

ilog.views.graphlayout.IlvGraphLayoutLinkProperty

ilog.tgo.graphic.graphlayout.IltLinkLayoutLinkProperty

All Implemented Interfaces:

IlvPersistentObject, Serializable

public class IltLinkLayoutLinkProperty
extends IlvGraphLayoutLinkProperty

The class IltLinkLayoutLinkProperty allows you to store the settings of an instance of IltLinkLayout for an individual link as a named property in the link. This is used by IlvGrapherAdapter.saveParametersToNamedProperties(IlvGraphLayout, boolean) which is an auxiliary to be used before IlvManager.write(IlvOutputStream) if you want to store layout parameter settings in .ivl files.

Since:

JTGO 2.6

Constructor Detail

IltLinkLayoutLinkProperty

public IltLinkLayoutLinkProperty(String name,
                                 IltLinkLayout layout,
                                 IlvGraphic link,
                                 boolean withDefaults)

Creates a new IltLinkLayoutLinkProperty that stores layout parameter settings of the layout for the link.

Parameters:

name - The name of the property.

layout - The layout instance to be stored.

link - The link whose layout parameters are to be stored.

withDefaults - If true, the layout property is always persistent. If false, it is persistent only if nondefault parameter settings exist (that is, if the the property is saved to an .ivl file, the default parameter settings are not saved).

IltLinkLayoutLinkProperty

public IltLinkLayoutLinkProperty(IltLinkLayoutLinkProperty source)

Creates a new IltLinkLayoutLinkProperty by copying an existing one.

Parameters:

source - The origin of the copy.

Internal: do not use!

IltLinkLayoutLinkProperty

public IltLinkLayoutLinkProperty(IlvInputStream stream)
                          throws IOException,
                                 IlvReadFileException

Creates a new IltLinkLayoutLinkProperty from an IlvInputStream.

Parameters:

stream - The input stream from which the property must be read.

Throws:

IlvReadFileException - if an error occurs while reading.

IOException

Internal: do not use!

Method Detail

copy

public IlvNamedProperty copy()

Copies the named property.

Overrides:

copy in class IlvGraphLayoutLinkProperty

Internal: do not use!

isPersistent

public boolean isPersistent()

Returns true if the property must be saved to an .ivl file.

Overrides:

isPersistent in class IlvGraphLayoutLinkProperty

Internal: do not use!

write

public void write(IlvOutputStream stream)
           throws IOException

Writes the property to the output stream.

Specified by:

write in interface IlvPersistentObject

Overrides:

write in class IlvGraphLayoutLinkProperty

Parameters:

stream - The output stream.

Throws:

IOException - standard IO error.

Internal: do not use!

transfer

public void transfer(IlvGraphLayout graphLayout,
                     IlvGraphic link)

Transfers the layout parameter settings stored in this named property back to the input layout for the input link.

Overrides:

transfer in class IlvGraphLayoutLinkProperty

Parameters:

graphLayout - The layout instance whose parameters are to be recovered from this named property.

link - The link whose layout parameters are to be recovered from this named property.

Internal: do not use!

dispose

public void dispose(IlvGrapherAdapter adapter)

Disposes of the property and releases any resources that it is using. This is called if the property was loaded and removed from the grapher.

Overrides:

dispose in class IlvGraphLayoutLinkProperty

Parameters:

adapter - The grapher adapter.

Since:

JViews 5.0
