Package net.sf.saxon.z

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.

Interface Summary

Interface	Description
IntIterator	An iterator over a sequence of unboxed int values.
IntPredicateProxy	This interface represents an integer predicate (that is, a boolean function of an integer).
IntToIntMap	Interface defining a map from integers to integers

Class Summary

Class	Description
ConcatenatingIntIterator	An iterator over nodes, that concatenates the nodes returned by two supplied iterators.
IntArraySet	Set of int values.
IntArraySet.IntArrayIterator	Iterator class: iterate over an array of integers
IntBlockSet	Set of int values.
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 union of two other predicates: it matches an integer if either of the operands matches the integer
IntPredicateLambda	This class allows an integer predicate (a boolean function of an integer) to be written as a lambda expression, in a way that works both in Java and C#.
IntRangeSet	Set of int values.
IntRangeToIntMap	Set of int values.
IntRepeatIterator	An iterator over a single integer repeated a fixed number of times
IntSet	A set of integers represented as 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
MonotonicIntSet	Set of int values.
