Detailed Description
CPU device context managment class
This class provides functions to manage CPU device contexts.
Notes:
- These are reference counted objects, like nodes, and must be created using the new operator (not on the stack).
- Unlike node classes the initial reference count is one, not zero.
Therefore to delete a device context, just call unref(). Do not call ref() and unref(). Do not use SoRef with these classes.
- See related examples:
Constructor & Destructor Documentation
| SoCpuContext::SoCpuContext | ( | SoCpuDevice * | device = NULL |
) |
Default constructor.
- Parameters:
-
device The SoCpuDevice on which to create the context.
Member Function Documentation
| virtual void SoCpuContext::bind | ( | ) | [virtual] |
Bind this context to the current thread.
Implements SoDeviceContext.
| static SoCpuContext* SoCpuContext::getCurrent | ( | ) | [static] |
Returns the currently bound context (if any) for the current thread.
- Returns:
- The current CPU context.
| 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.
| virtual bool SoCpuContext::isCurrent | ( | ) | const [inline, virtual] |
Query if the context is valid and currently active.
Implements SoDeviceContext.
| virtual void SoCpuContext::unbind | ( | ) | [virtual] |
Unbind this context from the current thread.
Implements SoDeviceContext.
