Interface Summary

Interface	Description
IntIterator	An iterator over a sequence of unboxed int values
IntPredicate	Interface defining a predicate that can be tested to determine whether an integer satisfies, or does not satisfy, some condition.
IntSet	A set of integers represented as int values
IntToIntMap	Interface defining a map from integers to integers

Class Summary

Class	Description
AbstractIntSet	Abstract superclass containing helper methods for various implementations of IntSet
IntArraySet	Set of int values.
IntBlockSet	Set of int values.
IntCheckingSet	An immutable integer set where membership is tested algorithmically
IntComplementPredicate	An IntPredicate formed as the complement of another predicate; it matches an integer if the operand does not, and vice versa.
IntComplementSet	An immutable integer set containing all int values except those in an excluded set
IntEmptySet	An immutable integer set containing no integers
IntExceptPredicate	An IntPredicate formed as the difference of two other predicates: it matches an integer if the first operand matches the integer and the second does not
IntHashMap<T>	A hash table that maps int keys to Object values.
IntHashSet	Set of int values.
IntIntersectionPredicate	An IntPredicate formed as the intersection of two other predicates: it matches an integer if both of the operands matches the integer
IntRangeSet	Set of int values.
IntSetPredicate	An implementation of IntPredicate that tests whether a given integer is a member of some IntSet
IntSingletonIterator	An iterator over a single integer
IntSingletonSet	An immutable integer set containing a single integer
IntStepIterator	An iterator over a sequence of integers with regular steps, e.g.
IntToIntArrayMap	An implementation of IntToIntMap that relies on serial searching, and is therefore optimized for very small map sizes
IntToIntHashMap	A hash table that maps int keys to int values.
IntUnionPredicate	An IntPredicate formed as the union of two other predicates: it matches an integer if either of the operands matches the integer
IntUniversalSet	An immutable integer set containing every integer
IntValuePredicate	An IntPredicate that matches a single specific integer

Package net.sf.saxon.z Description

This package provides utility routines for handling integer sets and maps.

The main classes are IntSet which represents a set of 32-bit integers (int values), IntIterator which is an iterator over a sequence of 32-bit integers, IntHashMap which is a map from 32-bit integers to arbitrary objects, and IntToIntMap which is a map from 32-bit integers to 32-bit integers.

The package name is a pun on the conventional use by mathematicians of the symbol Z to denote the set of all natural integers.
