MoML
ptolemy.kernel.util.NamedObj or any derived class, although most useful models will be
instances of ptolemy.kernel.CompositeEntity or a derived class. TypedCompositeActor,
as in the above example, is derived from CompositeEntity.
7.3.5 Entity Element
A model typically contains entities, as in the following Ptolemy II example:
Notice the common XML shorthand here of writing “” rather than “.” Of course, the shorthand only works if there is nothing in the body of the entity
element.
An entity can contain other entities, as shown in this example:
An entity must specify a class unless the entity already exists in the containing entity or model. The
name of the entity reflects the container hierarchy. Thus, in the above example, the source entity has
the full name “.ptIImodel.container.source”.
The definition of an entity can be distributed in the MoML file. Once created, it can be referred to
again by name as follows:
...
The property element (see section 7.3.6 below) is added to the pre-existing entity with name “x” when
the second entity element is encountered.
In principle, MoML supports multiple containment, as in the following:
