Class SeedTransformer<T>

java.lang.Object

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

Type Parameters:

T - type of default

All Implemented Interfaces:

FunctionTransformer<Void,T>, Serializable, Function<Void,T>, Supplier<T>, org.apache.commons.collections.Transformer

public class SeedTransformer<T>
extends Object
implements FunctionTransformer<Void,T>, Supplier<T>, Serializable

A Transformer that does not consider the input parameter and is usually the Seed for a Chain of transformations.
It allows for wrapping of a core object that it provides as the Seed and returns when Transformer.transform(Object) is called.

This also converts Supplier & Transformer types (triggers them) and does not consider them to be passed as seed itself.
