java.lang.Object
net.sf.saxon.evpull.BlockEventIterator
- EventIterator, PullEvent
public class BlockEventIterator
extends java.lang.Object
Iterate over the instructions in a Block, concatenating the result of each instruction
into a single combined sequence.
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 item in the sequence.

BlockEventIterator
public BlockEventIterator(Expression[] children,
XPathContext context)
Create an EventIterator over the results of evaluating a Block
children
- the sequence of instructions comprising the Blockcontext
- the XPath dynamic context
isFlatSequence
public boolean isFlatSequence()
Determine whether the EventIterator returns a flat sequence of events, or whether it can return
nested event iterators
- isFlatSequence in interface EventIterator
- true if the next() method is guaranteed never to return an EventIterator
