Overrides:

startElement in class org.xml.sax.helpers.DefaultHandler

doneLoader

public void doneLoader(int tagId,
                       java.lang.StringBuffer charData,
                       java.lang.Object o)

Description copied from interface: XMLLoaderChainElement

Called after the currently active loader encounters its end tag. Implementer is responsible for set content handler back to itself. Note that this is symmetrical in thart objects set themselves to be content handlers initially.

Specified by:

doneLoader in interface XMLLoaderChainElement

Parameters:

tagId - the integer id of the tag that just finished

charData - the character data that was read for that tag

o - arbitrary parameter to pass back to the invoking loader
