The list of created objects.

Constructor Detail

GraphTransformer.CreateObjectChangeRequest

public GraphTransformer.CreateObjectChangeRequest(NamedObj context,
                                                  java.lang.String request)

Construct a mutation request to be executed in the specified context. The context is typically a Ptolemy II container, such as an entity, within which the objects specified by the MoML code will be placed. This method resets and uses a parser that is a static member of this class. A listener to changes will probably want to check the originator so that when it is notified of errors or successful completion of changes, it can tell whether the change is one it requested. Alternatively, it can call waitForCompletion(). All external references are assumed to be absolute URLs. Whenever possible, use a different constructor that specifies the base.

Parameters:

context - The context in which to execute the MoML.

request - The mutation request in MoML.
