A "EmbProxiedObj.T" is a Modula-3 object for which we want to have proxy, an object that mirrors this object in some way. The prototypical use is to connect Modula-3 objects to their counterparts in some embedded interpreted language (e.g. Obliq).
Browse Sources OnlineThe shared object package is designed to complement Network objects. A network object allows an object to be shared by multiple processes, possibly on different machines, by creating surrogate objects in all processes except the one in which the object actually exists. From the point of view of the programmer and the executing program, the surrogate object behaves exactly like the original object. However, all method calls to the surrogates are synchronously sent to the original object where they are executed, with return values or exceptions propogated back to the calling process.
For many applications, this is sufficient and has many desirable properties: there are no sychronization issues, calls are synchronous so exceptions propogate across processes, global garbage collection is performed, etc. However, for some applicates, the paradigm is not appropriate. The sychronous nature method calls restricts the frequency and of checking the object for changes. More seriously, interested parties are restricted to polling an object if they are interested in changes. Finally, all operations on an object, no matter how trivial, require a remote procedure call, which takes a significant amount of time.
To address these problems, and others, the shared object package was created. The model is the opposite of the network object package and is intended to complement rather that replace it. Instead of the object being stored at one location and remote method calls being used to access the object, shared objects are fully replicated in all interested processes, with any updates to the object being applied to all copies.

Browse Sources OnlineObliq - a lightweight language for network objects
An interactive interpreter for the Obliq language. Obliq is a small, statically scoped, untyped language. It is object-oriented, higher-order, and distributed. State is local to an address space, while computation can migrate over the network. The distributed computation mechanism is based on Modula-3 Network Objects.
Obliq requires copies of netobjd to be running on all appropriate machines, if network objects are to be used.

Browse Sources Onlinevisobliq - Visual Obliq: programming environment for distributed applications
Visual Obliq is a programming environment for multi-user applications, expressed in the Obliq language.
In the Visual Obliq model, a distributed session is started by loading an application into an Obliq interpreter. This creates a session with a certain unique public name. Users running interpreters at other sites can connect to the session via the session-name. The act of joining a session causes the appropriate client code and user interface specification to migrate to the client's address-space and run there.
All the above activities can be supported and coordinated within the World-Wide Web framework. A Visual Obliq program may be regarded as a document with an appropriate MIME type. The text of an application is disseminated as a MIME-encapsulated document by a Visual Obliq gateway (vocgi).
