Method Detail

onComponentTag

protected MarkupElement onComponentTag(ComponentTag tag)
                                throws ParseException

Get the next tag from the next MarkupFilter in the chain and search for Wicket specific tags.

Note: The xml parser - the next MarkupFilter in the chain - returns XmlTags which are a subclass of MarkupElement. The implementation of this filter will return either ComponentTag or WicketTag. Both are subclasses of MarkupElement and both maintain a reference to the XmlTag. But no XmlTag is returned.

Specified by:

onComponentTag in class AbstractMarkupFilter

Returns:

The next tag from markup to be processed. If null then no more tags are available

Throws:

ParseException
