Class Source<T>

java.lang.Object

com.redhat.lightblue.assoc.ep.Source<T>

public final class Source<T>
extends Object

This class is used to refer to a source step. The source step of another step is sometimes given as a definite step, and sometimes as the result step of an execution block. However, during execution plan construction, not all execution blocks have a result step yet. So, this class defers the initialization of source until it is needed
