The Map StyleSheet Renderer

The Map StyleSheet renderer is the a specific version of The StyleSheet Renderer. You need to have ILOG JViews Maps installed with a valid license to be able to use this renderer.

The Map StyleSheet renderer wraps the node and link layers into an IlvMapLayer object. This is done in order for them to be managed by the maps layer tree. For example, this allows the following:

Interactive raising and lowering of layers.
Indication that the layers are always on top of the map background.

In a JViews Maps application you have to enable the Map StyleSheet renderer using Java code before you make any use of a style sheet. The following code example shows how to replace the StyleSheet renderer:

 // replace the stylesheet renderer with map rendererclass.
 IlvRendererUtil.addRendererAlias(
 IlvRendererUtil.getRendererAlias(IlvStyleSheetRenderer.class.getName()),
 IlvMapStyleSheetRenderer.class.getName());

The Map StyleSheet renderer provides exactly the same properties as the StyleSheet Renderer. However, any use of the nodesLayer, linksLayer or Layer properties will be overridden by the Map Layer tree order. Table 4.25 lists the Map StyleSheet renderer properties.

Table 4.25 The Map StyleSheet Renderer Global Properties

Property	Type	Default	Description
debugMask	int	0	Prints selected debug information.
styleSheets	String[]	null	Sets cascading style sheets. This property is usually set on the SDM engine rather than directly on the StyleSheet renderer.
linkConnectorEnabled	boolean	true	Specifies if a link connector should be installed to connect the links to the sides of the nodes, rather than to their centers.
addingLinkConnectors	boolean	true	If `false`, no link connector is installed by the style sheet renderer.

Table 4.26 lists the Map StyleSheet renderer per-object rendering properties.

Table 4.26 The Map StyleSheet Renderer Per-Object Proprieties

Property	Type	Default	Description
Anchor	int	Center	The position of the object's location relative to its bounding box (for example, Top Left? will place the object so that its upper-left corner is located at the x, y position).
LinkConnector	IlvLinkConnector		Defines the link connector set on the nodes of the graph. By default, an `IlvSDMLinkConnector` object is used.
ToolTipText	String	null	Deprecated, replaced by the `Ilv Graphic` property, `toolTipText`.
x	float		The horizontal coordinate of the object.
y	float		The vertical coordinate of the object.
width	int		The width of the object. If the width is not specified in the style sheet file, and if it is specified in the data model XML file, the value contained in the XML file will be used. See `IlvSDMRenderer.getGraphicProperty` for details.
height	int		The height of the object. If the height is not specified in the style sheet file, and if it is specified in the data model XML file, the value contained in the XML file will be used. See IlvSDMRenderer.getGraphicProperty for details.
