Class JpaEntityPointerDefinition

java.lang.Object

com.evolveum.midpoint.repo.sql.query2.definition.JpaDataNodeDefinition

com.evolveum.midpoint.repo.sql.query2.definition.JpaEntityPointerDefinition

All Implemented Interfaces:

Visitable, DebugDumpable

public class JpaEntityPointerDefinition
extends JpaDataNodeDefinition

Special placeholder to allow for cross-references: entity definition that points to another entity. Currently, the process of resolving allows to point to root entity definitions here only. As a hack, we implement self pointers (e.g. RAssignment.metadata->RAssignment) also for non-root entities, provided they are resolved on creation. (The reason of using JpaEntityPointerDefinition there is just to break navigation cycles e.g. when using a visitor.)

Description copied from class: JpaDataNodeDefinition

Tries to find "next step" in the translation process for a given ItemPath.

Specified by:

nextLinkDefinition in class JpaDataNodeDefinition

Parameters:

path - A path to be resolved. Always non-null and non-empty. Should produce at least one transition.

itemDefinition - Item definition for the item being sought. Needed only for "any" items.

Returns:

- Normally it returns the search result containing next item definition (entity, collection, ...) in the chain and the unresolved remainder of the path. The transition may be empty ("self") e.g. for metadata or construction. - If the search was not successful, returns null.

Throws:

QueryException
