Method Detail

startPageSequence

public void startPageSequence(Locale locale,
                              String role)

Starts a page sequence structure tree node.

Specified by:

startPageSequence in interface StructureTreeEventHandler

Parameters:

locale - The locale of the page sequence

role - the value of the role property. May be null.

endPageSequence

public void endPageSequence()

Ends a page sequence structure tree node.

Specified by:

endPageSequence in interface StructureTreeEventHandler

startNode

public StructureTreeElement startNode(String name,
                                      Attributes attributes,
                                      StructureTreeElement parent)

Starts a structure tree node.

Specified by:

startNode in interface StructureTreeEventHandler

Parameters:

name - the name of the structure tree node

attributes - the node properties

parent - 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

public void endNode(String name)

Ends a structure tree node.

Specified by:

endNode in interface StructureTreeEventHandler

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:

startImageNode in interface StructureTreeEventHandler

Parameters:

name - the name of the structure tree node

attributes - the node properties

parent - 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

startReferencedNode

public StructureTreeElement startReferencedNode(String name,
                                                Attributes attributes,
                                                StructureTreeElement parent)

Starts a node that can be referenced by other nodes. This is usually a node that can have Marked Content References as children.

Specified by:

startReferencedNode in interface StructureTreeEventHandler

Parameters:

name - the name of the structure tree node

attributes - the node properties

parent - 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
