Deprecated Classes

csp.lang.Channel_of_Proxy
The name Proxy is not the best choice. A proxy means more than just a container class holding a reference to an object and a tag variable. We renamed the Proxy class to Reference class, which is more appropriate. See Channel_of_Reference class. The Channel_of_Proxy class provides a communication channel for passing any Proxy objects between processes.

csp.lang.Proxy
The name Proxy is not the best choice. A proxy means more than just a container class holding a reference to an object and a tag variable. We renamed the Proxy class to Reference class, which is more appropriate. See Reference class. The Proxy object is a wrapper object that holds a public Object variable object to store the object and a public int tag variable of store the message type.

The variable tag must be zero or higher ([0, ->]). An undefined tag is marked as UNDEFINED (default).

After writing the object, the reference to this object will be set to null. This prevents sharing the object by more than one processes. This protection in not entirely secure because the sender may hold a copy of the reference and may therefore share the object -- this choice is up to the programmer.
