# Interpreter Concurrency Source Files

This directory contains files used to implement the underlying ooRexx thread management. Many of the classes here a just supporting role players used for initiating calls into the interpreter or callouts from the interpreter.

The following is a partial list of the files to be found in this subdirectory.

ActivityManager.*
  The master subsystem form managing threading issues. ooRexx uses a cooperative threading model, with only a single thread capable of running interpreter code at one time. The ActivityManager handles the thread synchronization, scheduling, and dispatching needed to implement the multi-threaded behavior.
RexxActivity.*
  A RexxActivity instance represents a thread of execution inside of an interpreter instance. Each active thread that the interpreter knows about will have a RexxActivity object allocated for it. The RexxActivity manages the execution stack and also performs some memory management functions on behalf of the memory subsystem.
