Class TerminatedIntIterator

java.lang.Object
  net.sf.saxon.expr.sort.TerminatedIntIterator

All Implemented Interfaces:

IntIterator

public class TerminatedIntIterator
extends Object
implements IntIterator

An iterator over a sequence of integers held in an array. The array may either be exactly the right size, or may be terminated by an end-of-sequence value.

This data structure is generally used for a sequence of namespace codes.

Constructor Summary

TerminatedIntIterator(int[] values)
Construct an iterator over a sequence of integers held in an array, with the value -1 acting as the terminator

TerminatedIntIterator(int[] values, int terminator)
Construct an iterator over a sequence of integers held in an array, with a specified value acting as the terminator

Method Summary

boolean	hasNext() Test whether there are any more integers in the sequence
int	next() Return the next integer in the sequence.

Constructor Detail

TerminatedIntIterator

public TerminatedIntIterator(int[] values)

Construct an iterator over a sequence of integers held in an array, with the value -1 acting as the terminator

Parameters:

values - the sequence of integers

TerminatedIntIterator

public TerminatedIntIterator(int[] values,
                             int terminator)

Construct an iterator over a sequence of integers held in an array, with a specified value acting as the terminator

Parameters:

values - the sequence of integers

terminator - the terminator value

Method Detail

hasNext

public boolean hasNext()

Test whether there are any more integers in the sequence

Specified by:

hasNext in interface IntIterator

Returns:

true if there are more integers to come

next

public int next()

Return the next integer in the sequence. The result is undefined unless hasNext() has been called and has returned true.

Specified by:

next in interface IntIterator

Returns:

the next integer in the sequence
