Method Summary

Modifier and Type	Method and Description
List<Element>	content(WorkerContext ctx, Tag tag, String content) This method is called if there is text content encountered between the opening and closing tags this TagProcessor is mapped to.
List<Element>	endElement(WorkerContext ctx, Tag tag, List<Element> currentContent) This method is called when a closing tag has been encountered of the TagProcessor implementation that is mapped to the tag.
boolean	isStackOwner()
List<Element>	startElement(WorkerContext ctx, Tag tag) This method is called when a tag has been encountered.

Method Detail

startElement

List<Element> startElement(WorkerContext ctx,
                           Tag tag)

This method is called when a tag has been encountered.

Parameters:

ctx - the WorkerContext

tag - the tag encountered

Returns:

Element an Element to add to the current content;

content

List<Element> content(WorkerContext ctx,
                      Tag tag,
                      String content)

This method is called if there is text content encountered between the opening and closing tags this TagProcessor is mapped to.

Parameters:

ctx - the WorkerContext

tag - the tag encountered

content - the text content between the tags this TagProcessor is mapped to.

Returns:

the element to add to the currentContent list

endElement

List<Element> endElement(WorkerContext ctx,
                         Tag tag,
                         List<Element> currentContent)

This method is called when a closing tag has been encountered of the TagProcessor implementation that is mapped to the tag.

Parameters:

ctx - the WorkerContext

tag - the tag encountered

currentContent - a list of content possibly created by TagProcessing of inner tags, and by startElement and content methods of this TagProcessor .

Returns:

the resulting element to add to the document or a content stack.

isStackOwner

boolean isStackOwner()
