public abstract class BoundedBufferProcess

extends Process

A BoundedBufferProcess is a process that works with two buffer queues, one with empty buffers and one with full buffers. The buffer queues are specified in the class constructor.

This class is abstract. Concrete subclasses must implement the step() method.

Field Summary

protected BufferQueue	empty empty is the queue for empty buffers used by this bounded buffer process.
protected BufferQueue	full full is the queue for full buffers used by this bounded buffer process.

Constructor Summary

BoundedBufferProcess(java.lang.String nm, double t, BufferQueue f, BufferQueue e)
new BoundedBufferProcess(nm, t, f, e) returns a new bounded buffer process and starts executing its run method in a new thread.

Methods inherited from class Process

empty

protected BufferQueue empty

empty is the queue for empty buffers used by this bounded buffer process.

full

protected BufferQueue full

full is the queue for full buffers used by this bounded buffer process.

Constructor Detail

BoundedBufferProcess

public BoundedBufferProcess(java.lang.String nm,
                            double t,
                            BufferQueue f,
                            BufferQueue e)

new BoundedBufferProcess(nm, t, f, e) returns a new bounded buffer process and starts executing its run method in a new thread. The name of the new process is formed by concatenating its class name with nm. The average twiddle time of the new process is t. The new process uses f as a queue for full buffers and e as a queue for empty buffers.
