org.apache.axiom.om.impl.builder.StAXOMBuilder
StAX based builder that produces a pure XML infoset compliant object model.
This class supports the {@link XMLStreamReader} extension defined by{@link org.apache.axiom.ext.stax.datahandler.DataHandlerReader} as well as the legacy extension mechanismdefined in the documentation of {@link org.apache.axiom.util.stax.XMLStreamReaderUtils}.
Error handling
Usually, code that uses StAX directly just stops processing of an XML document once the first parsing error has been reported. However, since Axiom uses deferred parsing, and client code accesses the XML infoset using an object model, things are more complicated. Indeed, if the XML document is not well formed, the corresponding error might be reported as a runtime exception by any call to a method of an OM node.
Typically the client code will have some error handling that will intercept runtime exceptions and take appropriate action. Very often this error handling code might want to access the object model again, for example to log the request that caused the failure. This causes no problem except if the runtime exception was caused by a parsing error, in which case Axiom would again try to pull events from the parser.
This would lead to a situation where Axiom accesses a parser that has reported a parsing error before. While one would expect that after a first error reported by the parser, all subsequent invocations of the parser will fail, this is not the case for all parsers (at least not in all situations). Instead, the parser might be left in an inconsistent state after the error. E.g. WSCOMMONS-372 describes a case where Woodstox encounters an error in {@link XMLStreamReader#getText()} but continues to return(incorrect) events afterwards. The explanation for this behaviour might be that the situation described here is quite uncommon when StAX is used directly (i.e. not through Axiom).
To avoid this, the builder remembers exceptions thrown by the parser and rethrows them during a call to {@link #next()}.
