Package it.bancaditalia.oss.vtl.impl.transform.util

Class ResultHolder<T>

java.lang.Object

java.util.AbstractMap<K,V>

java.util.concurrent.ConcurrentHashMap<Transformation,T>

it.bancaditalia.oss.vtl.impl.transform.util.ResultHolder<T>

Type Parameters:

T - The type of the transient results

All Implemented Interfaces:

Serializable, ConcurrentMap<Transformation,T>, Map<Transformation,T>

public class ResultHolder<T>
extends ConcurrentHashMap<Transformation,T>

Keeps transient results used in computations. Each computation can store a single result of a given type.
