public PendingItem(int sequenceNr)

Method Detail

getSequenceNr

public int getSequenceNr()

Get the sequence number of this item within a set of items representing nested nodes

Returns:

the sequence number

getGatherer

public abstract Receiver getGatherer()
                              throws XPathException

Get a receiver which will be notified of all events in the streamed input between the start event for this node and the corresponding end event. This Receiver gathers data into the pending item so that the final result of processing the streamed node can be computed by the deliver() method

Returns:

a receiver to be notified of all events relating to this streamed input node

Throws:

XPathException - if a dynamic error is detected

deliver

public abstract Sequence deliver()
                          throws XPathException

On completion of this streamed node, that is, when the relevant end tag is reached, compute the result of processing this node and return this result

Returns:

the result of processing a streamed input node

Throws:

XPathException - if the processing fails with a dynamic error

rollback

public abstract void rollback()

Reset the data relating to this node if a dynamic error occurs while processing the input stream.
