Method Detail

getMetadataStyle

public ViewStyle getMetadataStyle(Graph view,
                                  java.lang.Object metaData,
ViewStyle initStyle,
                                  int edge,
                                  int depth,
                                  int index)

Retrieves the ViewStyle that formats the cells of a paging control. The implementation of this method should create a RuleContext, and should use the RuleContext to run any rules that have been specified for paging control cells. The resulting ViewStyle is used by the graph to paint the paging control cell.

Parameters:

view - The graph whose paging control to format.

metaData - The metadata that will appear in the paging control cell. This is likely to be a dimension name or a dimension member. The method should store the type of data in the RuleContext.

initStyle - The initial ViewStyle that specifies formatting for the paging control cell.

edge - The edge to which this belongs. Should be oracle.dss.util.DataDirector.PAGE_EDGE.

depth - The layer of this header item within the edge.

index - The member in layer. edge, depth, and index identify the cell that is being formatted in the edge.

Returns:

The ViewStyle that specifies the formatting that the graph should use to paint the paging control cells.

setBundles

public void setBundles(DataviewCommon view,
                       java.util.Vector bundles)

Specifies the vector of RuleBundle objects to use. The vector is passed by value.

Parameters:

bundles - The vector of rule bundles that this manager should use.

RuleBundle

getBundles

public java.util.Vector getBundles()

Retrieves the vector of rule bundles that this manager uses to format Dataview items. Rule bundle vectors are passed by value. If you modify the vector that this method returns, call the setBundles method to set the modified vector.

Returns:

The vector of rule bundles that this manager uses.
