All Implemented Interfaces:

public class EISOneToManyQueryBasedValueHolder<T> extends org.eclipse.persistence.internal.indirection.QueryBasedValueHolder<T>
Value holder used to defer an EIS 1-m mapping query. For composite source foreign keys EIS 1-m's a query must be performed for each primary key, so a different type of value holder is required.
