public class ComponentTagHandler
extends org.xml.sax.helpers.DefaultHandler

The top level SAX event handler that receives event from the SAX parser when parsing a deployment descriptor. The top level element in a deployment descriptor can contain any number of children all of which can conditionally be wrapped in a processIf tag allowing for conditional parsing of one to many elements. This handler performs the switching between a filtering handler and a handler that routes events to the appropriate handlers of specific subsection of the descriptor tree.
