Package net.sf.saxon.expr.sort
Class IntHashSet
java.lang.Object
net.sf.saxon.expr.sort.AbstractIntSet
net.sf.saxon.expr.sort.IntHashSet
- All Implemented Interfaces:
Serializable
,IntSet
Set of int values. This class is modelled on the java.net.Set interface, but it does
not implement this interface, because the set members are nint's rather than Objects.
Not thread safe.

copy
Description copied from interface:IntSet
Create a copy of this IntSet that leaves the original unchanged. -
mutableCopy
Description copied from interface:IntSet
Create a copy of this IntSet that contains the same set of integers.- Specified by:
mutableCopy
in interfaceIntSet
- Returns:
- an IntSet containing the same integers. The result will not necessarily be the same class as the original. It will always be a mutable object
