Method Detail

getInternalObject

public java.lang.Object getInternalObject(MetaObject object)

Returns the internal object representation for the specified meta-object if one exists. For meta-object implementations that wrap an internal object, this will return the internal object. null is returned if the meta-object implementation does not internally wrap real objects.

Specified by:

getInternalObject in interface MetaKit

getMetaClassForObject

public MetaClass getMetaClassForObject(java.lang.Object object,
                                       MetaClassRegistry classRegistry)

Returns the appropriate meta-class for the specified object. If an appropriate meta-class has not been registered then this method returns null.

Specified by:

getMetaClassForObject in interface MetaKit

getMetaClassForObject

public MetaClass getMetaClassForObject(java.lang.Object object)

Returns the appropriate meta-class for the specified object. If an appropriate meta-class has not been registered then this method returns null. The meta-class is looked up in the context class registry.

Specified by:

getMetaClassForObject in interface MetaKit

wrapObject

public MetaObject wrapObject(java.lang.Object object,
                             MetaClass mClass)

Wraps the specified object in a meta-object adapter specific to this kit's implementation layer. Returns null if the object cannot be wrapped. Throws UnsupportedOperationException if this kit doesn't support wrapping.

Specified by:

wrapObject in interface MetaKit

getMetaObjectFactory

public MetaObjectFactory getMetaObjectFactory()

Returns a factory that can be used to create new MetaObject based values using this kit's underlying implementation.
