Constructor Details

SequenceIteratorOverJavaIterator

public SequenceIteratorOverJavaIterator(Iterator<J> javaIterator,
 BiFunction<J,Integer,Item> mapper)

Create a mapping iterator

Parameters:

javaIterator - the underlying Java iterator

mapper - a function to process each item. It takes two arguments, the item returned by the Java iterator, and a zero-based position incremented for each item.

Method Details

next

public Item next()

Description copied from interface: SequenceIterator

Get the next item in the sequence. This method changes the state of the iterator.

Specified by:

next in interface SequenceIterator

Returns:

the next item, or null if there are no more items. Once a call on next() has returned null, no further calls should be made. The preferred action for an iterator if subsequent calls on next() are made is to return null again, and all implementations within Saxon follow this rule.
