Description

The class of objects that are used for inter-thread synchronization.

There is no explicit mechanism in the library to block on a number of synchronization objects simultaneously, until synchronization can be achieved with one of them. This mechanism can be implemented by creating a new thread to wait for each synchronization object, and arranging for each thread to release a notification once synchronization has been achieved.

The name keyword is a string that is used as the synchronization object's name for convenience purposes, such as debugging.

Operations

The class <synchronization> provides the following operations:

wait-for: Block until synchronization can be achieved.
release: Release the object to make it available for synchronization.
synchronization-name: Returns the name of the synchronization object.
