CoreContext

Peter Ehrlich edited this page Jul 25, 2014 · 3 revisions

A context is a runtime generalization of the singleton pattern. Unlike a singleton, objects in a context are allowed to have a lifetime distinct from the lifetime of the enclosing application. Contexts also support a threading model via the CoreRunnable type, which is implemented by CoreThread and CoreJob.

Typical use cases

An anonymous context may be created with CoreContext::Create or with AutoCreateContext. A typical use pattern is as follows:

    // Make a new child context
    AutoCreateContext ctxt;
 
    // Make this context current
    CurrentContextPusher pshr(ctxt);

The above code creates a new context, and sets it current.
