startPageSequence
Starts a page sequence structure tree node.- Specified by:
startPageSequencein interfaceStructureTreeEventHandler- Parameters:
locale- The locale of the page sequencerole- the value of the role property. May be null.
-
endPageSequence
public void endPageSequence()Ends a page sequence structure tree node.- Specified by:
endPageSequencein interfaceStructureTreeEventHandler
-
startNode
public StructureTreeElement startNode(String name, Attributes attributes, StructureTreeElement parent) Starts a structure tree node.- Specified by:
startNodein interfaceStructureTreeEventHandler- Parameters:
name- the name of the structure tree nodeattributes- the node propertiesparent- the parent of the node. May be null, in which case the parent node is the node corresponding to the previous call to this method- Returns:
- the corresponding structure tree element
-
endNode
Ends a structure tree node.- Specified by:
endNodein interfaceStructureTreeEventHandler- Parameters:
name- the name of the structure tree node
-
startImageNode
public StructureTreeElement startImageNode(String name, Attributes attributes, StructureTreeElement parent) Starts an image node.- Specified by:
startImageNodein interfaceStructureTreeEventHandler- Parameters:
name- the name of the structure tree nodeattributes- the node propertiesparent- the parent of the node. May be null, in which case the parent node is the node corresponding to the previous call to this method- Returns:
