Interface ThingReference

All Known Subinterfaces:

DataReference, RemoteDataReference, RemoteThingReference

All Known Implementing Classes:

DataReferenceImpl, RemoteDataReferenceImpl, RemoteThingReferenceImpl, ThingReferenceImpl

public interface ThingReference

ThingReference is the VisAD interface for named holders for objects. It can provide a symbol table binding between a name and a variable for a user interface that includes a formula interpreter, or a full language interpreter (e.g., a Java interpreter).

During computations the object referenced by a ThingReference may change.

ThingReference is a source of ThingChangedEvent-s, and thus defines addThingChangedListener and removeThingChangedListener.

ThingReference objects may be local (ThingReferenceImpl) or remote (RemoteThingReferenceImpl).
