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

public final class JPACollectionFilterQuery
extends JPANavigationQuery

Create a sub query to filter on collection properties e.g. CollectionDeeps?$select=ID&$filter=FirstLevel/SecondLevel/Address/any(s:s/TaskID eq 'DEV') or CollectionDeeps?$filter=FirstLevel/SecondLevel/Comment/$count eq 2. This is done as sub-query instead of a join to have more straightforward way to implement OR or AND conditions
