Class SynchronizedHashMapFactory<K,V>

java.lang.Object
  org.jplate.foundation.util.impl.SynchronizedHashMapFactory<K,V>

Type Parameters:

K - The key type stored in HashMap.

V - The value type stored in HashMap.

All Implemented Interfaces:

java.io.Serializable, FactoryIfc<java.util.Map<K,V>>, MapFactoryIfc<K,V>

public final class SynchronizedHashMapFactory<K,V>
extends java.lang.Object
implements MapFactoryIfc<K,V>

Factory that creates synchronized Map's backed by HashMap's.

To create a synchronized HashMap containing keys Foo and value Bar, perform the following:

final SynchronizedHashMapFactory <Foo, Bar> factory =
    new SynchronizedHashMapFactory <Foo, Bar> ();

final Map sMap <Foo, Bar> = factory.create ();
