## org.biojava.bio.seq.io.game12
Class StAXFeatureHandler

    java.lang.Object
      org.biojava.utils.stax.StAXContentHandlerBase
          org.biojava.bio.seq.io.game12.StAXFeatureHandler

All Implemented Interfaces:
  StAXContentHandler

Direct Known Subclasses:
  GAMEAnnotationHandler, GAMEAspectHandler, GAMEDbxrefHandler, GAMEFeatureSetHandler, GAMEFeatureSpanHandler, GAMEGeneHandler, GAMEHandler, GAMEPropertyHandler, GAMESeqHandler, GAMESeqRelHandler, GAMESpanHandler

    public class StAXFeatureHandler

extends StAXContentHandlerBase

StAX handler shamelessly ripped off from Thomas Down's XFFFeatureSetHandler. It was modified for greater generality. NOTE This class is not thread-safe -- it must only be used for one parse at any time.

Since:
  1.2
Author:
  Thomas Down, David Huen

Field Summary
`StAXFeatureHandler` | `staxenv` Nesting class that provides callback interfaces to nested class

Method Summary
`protected void` | `addHandler(ElementRecognizer rec, StAXHandlerFactory handler)` Adds a feature to the Handler attribute of the StAXFeatureHandler object
`void` | `endElement(String nsURI, String localName, String qName, StAXContentHandler handler)` Handles basic exit processing.
`void` | `endElementHandler(String nsURI, String localName, String qName, StAXContentHandler handler)` Element specific exit handler Subclass to do anything useful.
`void` | `returnData(Object o)` provides a standardised way of returning an object that represents the result of parsing the child element
`void` | `startElement(String nsURI, String localName, String qName, Attributes attrs, DelegationManager dm)` Handles basic entry processing for all feature handlers.
`void` | `startElementHandler(String nsURI, String localName, String qName, Attributes attrs)` Element-specific handler.
