                           int depth,
                           int index)

Parameters:

metaData - member metadata

initStyle - initial ViewStyle for the member

edge - edge member is on

depth - layer member is in

index - slice member is in

Returns:

resulting ViewStyle for the given member

For internal use only. Application developers should not use this

exportGraphToStream

boolean exportGraphToStream(java.io.OutputStream out)

Parameters:

out - OutputStream object to use in exporting the graph

Returns:

boolean True if the export completed successfully, False otherwise

For internal use only. Application developers should not use this

Called when the graph must be rendered to the provided OutputStream

isPagingControlVisible
