Member Function Documentation

void osg::OperationThread::add

(

Operation *

operation

)

Add operation to end of OperationQueue, this will be executed by the graphics thread once this operation gets to the head of the queue.

virtual int osg::OperationThread::cancel ( )

virtual

Cancel this graphics thread.

Reimplemented from OpenThreads::Thread.

osg::ref_ptr<Operation> osg::OperationThread::getCurrentOperation ( )

inline

Get the operation currently being run.

Definition at line 194 of file OperationThread.h.

bool osg::OperationThread::getDone ( ) const

inline

Definition at line 201 of file OperationThread.h.

OperationQueue* osg::OperationThread::getOperationQueue ( )

inline

Get the OperationQueue.

Definition at line 173 of file OperationThread.h.

const OperationQueue* osg::OperationThread::getOperationQueue ( ) const

inline

Get the const OperationQueue.

void osg::OperationThread::remove

(

Operation *

operation

)

Remove operation from OperationQueue.

void osg::OperationThread::remove

(

const std::string &

name

)

Remove named operation from OperationQueue.

void osg::OperationThread::removeAllOperations

(

)

Remove all operations from OperationQueue.

virtual void osg::OperationThread::run ( )

virtual

Run does the opertion thread run loop.

Implements OpenThreads::Thread.

Reimplemented in osg::GraphicsThread.

void osg::OperationThread::setDone

(

bool

done

)

void osg::OperationThread::setOperationQueue

(

OperationQueue *

opq

)

Set the OperationQueue.
