Package com.sap.olingo.jpa.processor.core.query

Class JPAExpandQueryResult

java.lang.Object

com.sap.olingo.jpa.processor.core.query.JPAExpandQueryResult

All Implemented Interfaces:

JPAExpandResult, JPAConvertableResult

public final class JPAExpandQueryResult
extends Object
implements JPAExpandResult, JPAConvertableResult

Builds a hierarchy of expand results. One instance contains on the one hand of the result itself, a map which has the join columns values of the parent as its key and on the other hand a map that point the results of the next expand. The join columns are concatenated in the order they are stored in the corresponding Association Path.
