public class TShortHashSetDecorator extends java.util.AbstractSet<java.lang.Short> implements java.util.Set<java.lang.Short>, java.io.Externalizable
Wrapper class to make a TShortHashSet conform to the java.util.Set API. This class simply decorates an underlying TShortHashSet and translates the Object-based APIs into their Trove primitive analogs. Note that wrapping and unwrapping primitive values is extremely inefficient. If possible, users of this class should override the appropriate methods in this class and use a table of canonical values. Created: Tue Sep 24 22:08:17 PDT 2002- Author:

in interfacejava.util.Set<java.lang.Short>
- Overrides:
add
in classjava.util.AbstractCollection<java.lang.Short>
- Parameters:
value
- true if the set was modified by the insertion
-
equals
