The IlvBusLayout class supports the following
generic parameters defined in the
IlvGraphLayout
class (see Base class parameters and features):
Extra feature for JViews
Diagrammer:
The following sections describe the
particular way in which these parameters are used by this subclass.
Allowed time (BL)
The layout algorithm stops if the allowed time setting has
elapsed. (For a description of this layout parameter in the
IlvGraphLayout
class, see Allowed time.) The result code in the
layout report is
IlvGraphLayoutReport.STOPPED_AND_INVALID
.
Layout of connected components (BL)
The layout algorithm can use the generic mechanism to layout
connected components. (For more information about this mechanism,
see Layout of connected components.)
Layout region (BL)
The layout algorithm uses the layout region setting (either
your own or the default setting) to control the size and the
position of the graph drawing. All three ways to specify the
layout region are available for this subclass (See Layout region.)
The size of the layout is chosen with respect to the layout
region (see Dimensional parameters for the Bus Layout
algorithm). The height of the layout region is not taken into
account. The height of the layout will be smaller or larger,
depending on the number of nodes, the size of the nodes, and the
other specified parameters.
Link clipping (BL)
The layout algorithm can use a link clip interface to clip the
end points of a link. (See Link clipping.)
This is useful if the nodes have a nonrectangular shape such as a
triangle, rhombus, or circle. If no link clip interface is used,
the links are normally connected to the bounding boxes of the
nodes, not to the border of the node shapes. See Using a link clipping interface with the
Bus Layout for details of the link clipping mechanism.
Preserve fixed links (BL)
The layout algorithm does not reshape the links that are
specified as fixed. (See Preserve fixed links.)
Preserve fixed nodes (BL)
The layout algorithm does not move the nodes that are specified
as fixed. (See Preserve fixed nodes.)
Save parameters to named properties (BL)
The layout algorithm can save its layout parameters into named
properties. This can be used to save layout parameters to
.ivl
files. (For a detailed description of this feature, see Save parameters to named properties and Saving layout parameters and preferred
layouts.)
Stop immediately (BL)
The layout algorithm stops after cleanup if the method stopImmediately is called. (For a
description of this method in the
IlvGraphLayout
class, see Stop immediately.) If the layout stops
early because the allowed time has elapsed, the result code in
the layout report is
IlvGraphLayoutReport.STOPPED_AND_INVALID
.
