Detailed Description

VSG extension Abstract base class for device context managment

This class provides generic functions to manage or get data about specific device contexts.

Reference counting:

Constructor & Destructor Documentation

SoDeviceContext::SoDeviceContext (  ) 

Default constructor.

Member Function Documentation

virtual void SoDeviceContext::bind (  )  [pure virtual]

Bind this context to the current thread.

Implemented in SoCpuContext, and SoGLContext.

SoDeviceContextSharedGroup* SoDeviceContext::getSharedGroup (  )  const

Returns the current shared group.

virtual int SoDeviceContext::getSharedId (  )  const [virtual]

Returns an id common to all compatible/shared contexts.

virtual bool SoDeviceContext::isCompatible ( SoDeviceContext  )  const [pure virtual]

Returns true if two contexts are compatible.

Compatible means that using a buffer from one of these contexts inside the other will not require copying the data.

virtual bool SoDeviceContext::isCurrent (  )  const [pure virtual]

Returns true if the context is valid and currently active.

Implemented in SoCpuContext, and SoGLContext.

bool SoDeviceContext::isSharable (  )  const

Returns the sharable status of this context.

By default, a context is sharable.

virtual bool SoDeviceContext::isSharedWith ( const SoDeviceContext context  )  const [virtual]

Returns the current sharing state with passed context.

virtual bool SoDeviceContext::isValid (  )  const [virtual]

Returns true if this context is valid.

true if the context is valid.

Reimplemented in SoGLContext.

void SoDeviceContext::setSharable ( bool  sharable  ) 

Sets the sharable property.

bool SoDeviceContext::setSharedGroup ( SoDeviceContextSharedGroup sharedGroup  ) 

Explicitly change the sharedGroup.

virtual bool SoDeviceContext::setSharedWith ( SoDeviceContext sourceCtx  )  [virtual]

Share this context.

virtual void SoDeviceContext::unbind (  )  [pure virtual]

Unbind this context from the current thread.

Implemented in SoCpuContext, and SoGLContext.
