Method Detail

getNameCode

public int getNameCode()
Get the nameCode identifying the name of the current node. This method can be used after the ElementNameTracker, ElementNameTracker, ElementNameTracker, or ElementNameTracker events. With some PullProvider implementations, including this one, it can also be used after ElementNameTracker: in fact, that is the main purpose of this class. If called at other times, the result is undefined and may result in an IllegalStateException. If called when the current node is an unnamed namespace node (a node representing the default namespace) the returned value is -1.

Returns: the nameCode. The nameCode can be used to obtain the prefix, local name, and namespace URI from the name pool.

next

public int next()
Get the next event.

Note that a subclass that overrides this method is responsible for ensuring that current() works properly. This can be achieved by setting the field currentEvent to the event returned by any call on next().

Returns: an integer code indicating the type of event. The code ElementNameTracker is returned at the end of the sequence.
