java.lang.Object net.sf.saxon.evpull.Decomposer
public class Decomposer
This class takes a sequence of pull events and turns it into fully-decomposed form, that is, it takes and document and element nodes in the sequence and turns them into a subsequence consisting of a start element|document event, a content sequence, and an end element|document event, recursively.
The resulting sequence is decomposed, but not flat (it will contain nested EventIterators). To flatten
it, use EventStackIterator.flatten(EventIterator)
Constructor Summary | |
---|---|
Decomposer(EventIterator base,
PipelineConfiguration pipe)
Create a Decomposer, which turns an event sequence into fully decomposed form |
|
Decomposer(NodeInfo node,
PipelineConfiguration pipe)
Create a Decomposer which returns the sequence of events corresponding to a particular node |
Method Summary | |
---|---|
boolean |
isFlatSequence()
Determine whether the EventIterator returns a flat sequence of events, or whether it can return nested event iterators |
PullEvent |
next()
Get the next event in the sequence |
