All Implemented Interfaces:

Serializable, Cloneable, ValueHolderInterface<T>, WeavedAttributeValueHolderInterface<T>

public class EISOneToManyQueryBasedValueHolder<T>
extends 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.
