Class UsesIntermediateObjectWrapper<T extends org.apache.commons.collections.Transformer>

java.lang.Object

com.neurosys.etl.common.transformers.UsesIntermediateObjectImpl

com.neurosys.etl.common.transformers.UsesIntermediateObjectWrapper<T>

All Implemented Interfaces:

ContextAware, Lookup, FunctionTransformer, UsesIntermediateObject, Serializable, Function, org.apache.commons.collections.Transformer

public class UsesIntermediateObjectWrapper<T extends org.apache.commons.collections.Transformer>
extends UsesIntermediateObjectImpl
implements FunctionTransformer, Lookup

Allow a processor; Transformer, Lookup to be wrapped in this to allow for re-suing existing processors instead of extending UsesIntermediateObjectImpl for every new use case.
If the processor is null then it will simply return the input as is; i.e. the intermediate object
