Method Detail

getJavacServer

public JavacServer getJavacServer()

Return the javac server that this pool belongs to.

numActiveRequests

public int numActiveRequests()

Return how many threads are running at this very moment.

lastRequestFinished

public long lastRequestFinished()

Return when the last request was finished. I.e. the pool has been idle since.

startRequest

public int startRequest()

Up the number of active requests.

stopRequest

public long stopRequest()

Down the number of active requests. Return the current time.

execute

public void execute(CompilerThread ct)

Execute a compiler thread.

executeSubtask

public Future<?> executeSubtask(CompilerThread t,
                                Runnable r)

Execute a minor task, for example generating bytecodes and writing them to disk, that belong to a major compiler thread task.

shutdown

public void shutdown()

Shutdown the pool.

grabCompilerThread

public CompilerThread grabCompilerThread()
                                  throws InterruptedException

Acquire a compiler thread from the pool, or block until a thread is available. If the pools is empty, create a new thread, but never more than is "available".

Throws:

InterruptedException

returnCompilerThread

public void returnCompilerThread(CompilerThread h)

Return the specified compiler thread to the pool.
