Detailed Description

CPU device context managment class

This class provides functions to manage CPU device contexts.

Definition at line 38 of file SoCpuContext.h.

Constructor & Destructor Documentation

SoCpuContext()

SoCpuContext::SoCpuContext

(

SoCpuDevice *

device = NULL

)

Default constructor.

Parameters

device

The SoCpuDevice on which to create the context.

Member Function Documentation

bind()

virtual void SoCpuContext::bind ( )

virtual

Bind this context to the current thread.

Implements SoDeviceContext.

getCurrent()

static SoCpuContext * SoCpuContext::getCurrent ( )

static

Returns the currently bound context (if any) for the current thread.

Returns

The current CPU context.

isCompatible()

virtual bool SoCpuContext::isCompatible ( SoDeviceContext *  ) const

virtual

Query if the specified context and this one are compatible.

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

Returns

Returns true if the two contexts are compatible, false otherwise.

Implements SoDeviceContext.

isCurrent()

virtual bool SoCpuContext::isCurrent ( ) const

inlinevirtual

Query if the context is valid and currently active.

Implements SoDeviceContext.

Definition at line 73 of file SoCpuContext.h.

unbind()

virtual void SoCpuContext::unbind ( )

virtual

Unbind this context from the current thread.

Implements SoDeviceContext.
