Package net.sf.saxon.tree.iter Description

This package defines implementations and subinterfaces of the interface SequenceIterator, which is used to iterate over an XDM sequence.

The subinterfaces mostly represent iterators with additional capability: for example a LastPositionFinder can determine the number of items in the sequence without reading to the end; a GroundedIterator can deliver the original sequence as a list in memory; a LookaheadIterator is capable of one-item look-ahead. Note that just because a class implements such an interface does not mean it necessarily has this capability; it is necessary to check the properties of the specific iterator before assuming this.
