Maps from an object to the object's map representation (for an entity - only its id).

Specified by:

mapToMapFromObject in interface MiddleComponentMapper

Parameters:

session - The current session.

idData - Map to which composite-id data should be added.

public void addMiddleEqualToQuery(Parameters parameters,
                         String idPrefix1,
                         String prefix1,
                         String idPrefix2,
                         String prefix2)

Description copied from interface: MiddleComponentMapper

Adds query statements, which contains restrictions, which express the property that part of the middle entity with alias prefix1, is equal to part of the middle entity with alias prefix2 (the entity is the same). The part is the component's representation in the middle entity.

Specified by:

addMiddleEqualToQuery in interface MiddleComponentMapper

Parameters:

parameters - Parameters, to which to add the statements.

idPrefix1 - First alias of the entity + prefix + id to add to the properties.

prefix1 - First alias of the entity + prefix to add to the properties.

idPrefix2 - Second alias of the entity + prefix + id to add to the properties.

prefix2 - Second alias of the entity + prefix to add to the properties.
