lib.easyjava.net.tcp

Class ConnectionPool<S extends java.io.Serializable,R extends java.io.Serializable>

java.lang.Object

lib.easyjava.net.tcp.ConnectionPool<S,R>

Type Parameters:

S - the connections' send type

R - the connections' receive type

All Implemented Interfaces:

java.lang.Iterable<Connection<S,R>>, java.util.Collection<Connection<S,R>>, java.util.Set<Connection<S,R>>

public class ConnectionPool<S extends java.io.Serializable,R extends java.io.Serializable>
extends java.lang.Object
implements java.util.Set<Connection<S,R>>

Basically just a set of connections, but the waitForEvent() method allows blocking until one of the connections either receives something or closes.
