com.goldencode.p2j.persist.CompoundComponent

final class CompoundComponent
extends java.lang.Object

A helper container for a query component. A query component defines the Joinable object to which record retrieval tasks are delegated, the natural iteration type of this component query, and the type of join to perform with the previous component (if any).
