Direct Known Subclasses:

AttributeMapping

public class EntityMapping

extends jsdai.lang.ObjectMapping

This class is part of entity mapping implementation. It is intended for internal JSDAI use.

Constructor Summary

EntityMapping(SdaiSession session, ASdaiModel data, ASdaiModel mapping, java.util.Set touchedInstances)
Creates a new EntityMapping.

Method Summary

boolean	testMappedAttribute(EEntity targetInstance, jsdai.mapping.EGeneric_attribute_mapping sourceAttribute, int mode) Test whether a given targetInstance does fit to the contraints of attribute_mapping.
boolean	testMappedEntity(EEntity targetInstance, jsdai.mapping.EEntity_mapping sourceEntity, int mode) Test whether a given targetInstance does fit to the mapping of entity_mapping.

Constructor Detail

EntityMapping

public EntityMapping(SdaiSession session,
                     ASdaiModel data,
                     ASdaiModel mapping,
                     java.util.Set touchedInstances)
              throws SdaiException

Creates a new EntityMapping.

Parameters:

session - SdaiSession to attach to

data - The target data domain

mapping - The mapping domain

touchedInstances - The output parameter: the instances touched by mapping operations

Throws:

SdaiException - if an error occurs during the operation or in underlying JSDAI operations

Method Detail

testMappedEntity

public boolean testMappedEntity(EEntity targetInstance,
                                jsdai.mapping.EEntity_mapping sourceEntity,
                                int mode)
                         throws SdaiException

Test whether a given targetInstance does fit to the mapping of entity_mapping.

Parameters:

targetInstance - an instance, which is tested to be mapping of sourceEntity.

sourceEntity - an entity_mapping which mapping is tested

Returns:

true if this target instance is mapping of specified entity_mapping, false if is otherwise.

Throws:

SdaiException - if an error occurs during the operation or in underlying JSDAI operations

testMappedAttribute

public boolean testMappedAttribute(EEntity targetInstance,
                                   jsdai.mapping.EGeneric_attribute_mapping sourceAttribute,
                                   int mode)
                            throws SdaiException

Test whether a given targetInstance does fit to the contraints of attribute_mapping.

Parameters:

targetInstance - an instance to which parent entity_mapping of attribute_mapping is mapped

sourceAttribute - source attribute which mapping is tested

Returns:

true if this target instance has mapping of specified attribute mapping, false otherwise.

Throws:

SdaiException - if an error occurs during the operation or in underlying JSDAI operations
