Class SerializableHashMap<K extends IOReadableWritable,V extends IOReadableWritable>

java.lang.Object

java.util.AbstractMap<K,V>

java.util.HashMap<K,V>

org.apache.flink.runtime.util.SerializableHashMap<K,V>

Type Parameters:

K - the type of the key used in this hash map

V - the type of the value used in this hash map

All Implemented Interfaces:

Serializable, Cloneable, Map<K,V>, IOReadableWritable

public class SerializableHashMap<K extends IOReadableWritable,V extends IOReadableWritable>
extends HashMap<K,V>
implements IOReadableWritable

This class extends a standard HashMap by implementing the IOReadableWritable interface. As a result, hash maps of this type can be used with Nephele's RPC system.

This class is not thread-safe.
