Method Detail

allocate

public WorkspaceList.Lease allocate(FilePath base)
                             throws InterruptedException

Allocates a workspace by adding some variation to the given base to make it unique.

This method doesn't block prolonged amount of time. Whenever a desired workspace is in use, the unique variation is added.

Throws:

InterruptedException

allocate

public WorkspaceList.Lease allocate(FilePath base,
                                    Object context)
                             throws InterruptedException

See allocate(FilePath)

Parameters:

context - Threads that share the same context can re-acquire the same lock (which will just increment the lock count.) This allows related executors to share the same workspace.

Throws:

InterruptedException

record

public WorkspaceList.Lease record(FilePath p)

Just record that this workspace is being used, without paying any attention to the synchronization support.

acquire

public WorkspaceList.Lease acquire(FilePath p)
                            throws InterruptedException

Acquires the given workspace. If necessary, this method blocks until it's made available.

Returns:

The same FilePath as given to this method.

Throws:

InterruptedException

acquire

public WorkspaceList.Lease acquire(FilePath p,
                                   boolean quick)
                            throws InterruptedException

See acquire(FilePath)

Parameters:

quick - If true, indicates that the acquired workspace will be returned quickly. This makes other calls to allocate(FilePath) to wait for the release of this workspace.

Throws:

InterruptedException

acquire

public WorkspaceList.Lease acquire(FilePath p,
                                   boolean quick,
                                   Object context)
                            throws InterruptedException

See acquire(FilePath,boolean)

Parameters:

context - Threads that share the same context can re-acquire the same lock (which will just increment the lock count.) This allows related executors to share the same workspace.

Throws:

InterruptedException
