Class TCharSetDecorator

  • All Implemented Interfaces:
    java.io.Externalizable, java.io.Serializable, java.lang.Iterable<java.lang.Character>, java.util.Collection<java.lang.Character>, java.util.Set<java.lang.Character>
    public class TCharSetDecorator
extends java.util.AbstractSet<java.lang.Character>
implements java.util.Set<java.lang.Character>, java.io.Externalizable

    Wrapper class to make a TCharSet conform to the java.util.Set API. This class simply decorates an underlying TCharSet 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.
