static DynamicException	incompatibleDuplicateWriters(java.lang.String className, EclipseLinkClassWriter existingWriter, EclipseLinkClassWriter writer) A call to DynamicClassLoader#addClass(String, DynamicClassWriter) or DynamicClassLoader#creatDynamicClass(String, DynamicClassWriter) was invoked with a className that already had a DynamicClassWriter that is not compatible with the provided writer.
static DynamicException	invalidGetPropertyType(DatabaseMapping mapping, java.lang.ClassCastException cce) A request to get a persistent value from a DynamicEntity was made providing a propertyName that does exist but the provided return type failed when casting.
static DynamicException	invalidPropertyIndex(DynamicType type, int propertyIndex) Exception throw when attempting to access a dynamic property by index which does not have an associated mapping.
static DynamicException	invalidPropertyName(DynamicType type, java.lang.String propertyName) A request to get a persistent value from a DynamicEntity was made providing a propertyName that does not correspond to any mappings in the underlying descriptor.
static DynamicException	invalidSetPropertyType(DatabaseMapping mapping, java.lang.Object value) Invalid value attempted to be set into a DynamicEntity's property.

Method Detail

invalidPropertyName

public static DynamicException invalidPropertyName(DynamicType type,
                                   java.lang.String propertyName)

A request to get a persistent value from a DynamicEntity was made providing a propertyName that does not correspond to any mappings in the underlying descriptor.

See Also:

DynamicEntity.get(String)

invalidGetPropertyType

public static DynamicException invalidGetPropertyType(DatabaseMapping mapping,
                                      java.lang.ClassCastException cce)

A request to get a persistent value from a DynamicEntity was made providing a propertyName that does exist but the provided return type failed when casting. The generic type specified on the get method must be supported by the underlying value stored in the dynamic entity.

See Also:

DynamicEntity.get(String)

invalidSetPropertyType

public static DynamicException invalidSetPropertyType(DatabaseMapping mapping,
                                      java.lang.Object value)

Invalid value attempted to be set into a DynamicEntity's property. This could be caused by:

• Putting null into an property which is classified as primitive or a collection
• Putting a value into a property that cannot be assigned to the configured classification

Parameters:

mapping -

value -

Returns:

invalidPropertyIndex

public static DynamicException invalidPropertyIndex(DynamicType type,
                                    int propertyIndex)

Exception throw when attempting to access a dynamic property by index which does not have an associated mapping. Make sure the index used is less then DynamicType.getNumberOfProperties().

DynamicTypeImpl#getMapping(int)

illegalDynamicClassWriter

public static DynamicException illegalDynamicClassWriter(DynamicClassLoader loader,
                                         java.lang.String parentClassName)

A DynamicClassWriter was attempted to be instantiated with a null loader or invalid parentClassName. The parentClassName must not be null or an empty string.

entityNotFoundException

public static DynamicException entityNotFoundException(java.lang.String message)

A DynamicEntity could not be found

entityHasNullType

public static DynamicException entityHasNullType(DynamicEntity entity)

The DynamicEntity has a null type indicating an illegal state of the entity.

See Also:

DynamicEntityImpl.getType()

illegalParentClassName

public static DynamicException illegalParentClassName(java.lang.String parentClassName)

A null or empty string was provided as the parent class for a dynamic class being registered for creation.

DynamicClassWriter(String)

incompatibleDuplicateWriters

public static DynamicException incompatibleDuplicateWriters(java.lang.String className,
                                            EclipseLinkClassWriter existingWriter,
                                            EclipseLinkClassWriter writer)

A call to DynamicClassLoader#addClass(String, DynamicClassWriter) or DynamicClassLoader#creatDynamicClass(String, DynamicClassWriter) was invoked with a className that already had a DynamicClassWriter that is not compatible with the provided writer.
