> Filter is interface and extends XMLStreamReader. Filter wraps XMLStreamReader. And XMLStreamReader of StAXBuilder is replaced by Filter.
> In building phase, next() method must be invoked on each event. filter get result of next() from XMLStreamReader, and do some process, then return the result to StAXBuilder.
> We can set Object on filter. Filter get some information from it and set result on it to transfer the result.
> We can set StAXBuilder on filter. Filter get OMDocument from the builder. If filter want to know past information, the OMDocument has it.
> If StAXBuilder has lastNode() method, Filter can make reference list to OMNode. this is commneted in http://issues.apache.org/jira/browse/WSCOMMONS-75 .
> Example1)
> SOAP header has some child elements. and they has actor Attribute. it indicates which intermediary should process the element.
> ExtractMyActorSOAPHeaderFilter.java is implementation of Filter for this example. The filter monitors locaName at first,
> If START_ELEMENT whose actor does not equals myactor is found, The filter invokes next() until the element's END_ELEMENT.
> Thus, The soap header elements which has other's actor are not transfered to StAXBuilder. We can ommit creating fruitness OM.
> Example2)
> If StAXBuilder has lastNode() method, Filter can make reference list. The list has OMNode whose actor indicates myactor.
> After building, If we want to access Security header elements which has myactor, we can access the element directry by using the reference list.
