Public Member Functions

 SoInteropBufferObject ()
 Default constructor.
 
virtual SoBufferObjectcreateInstance () const =0
 Create a new buffer with the same properties as the current one.
 
virtual void clearInstance ()=0
 Free the memory allocated by the buffer object.
 
- Public Member Functions inherited from SoBufferObject
void lockBuffer ()
 Locks the buffer against concurrent calls from different threads.
 
void unlockBuffer ()
 Unlocks the buffer object.
 
virtual bool setSize (size_t size)
 Sets the size in bytes of the buffer object.
 
virtual size_t getSize () const
 Returns the size, in bytes, of the buffer object.
 
virtual void * map (AccessMode accessMode, size_t offset=0, size_t count=SO_BUFFER_SIZE_ALL)
 Map the buffer to a system memory address and allows the mapping of a sub part of the buffer object into CPU memory.
 
virtual void unmap ()
 Unmaps the buffer from CPU address space.
 
virtual void map (SoBufferObject *targetBufferObject, AccessMode accessMode, size_t startPosition=0, size_t mappingSize=SO_BUFFER_SIZE_ALL)
 Maps the current buffer object into the specified buffer object.
 
virtual void unmap (SoBufferObject *bufferObject)
 Unmap this buffer from the specified buffer object.
 
virtual void memcpy (SoBufferObject *sourceBufferObject, size_t destOffset=0, size_t sourceOffset=0, size_t copySize=SO_BUFFER_SIZE_ALL)
 Copies data from the specified buffer object into this buffer object.
 
virtual void memset (void *value, size_t valueSize=1, size_t offset=0, size_t count=SO_BUFFER_SIZE_ALL)
 This function sets the contents of (or a portion of) this buffer object to the specified value.
 
SoDeviceContextgetContext () const
 Returns the device context where this buffer is valid.
 
SoBufferObjectgetMappedBufferObject () const
 Returns a pointer to the buffer object which is mapped by the actual object.
 
AccessMode getMappedBufferObjectAccessMode ()
 Returns the access mode used for the buffer mapping.
 
size_t getMappedBufferObjectPosition () const
 Returns the position in the source buffer mapped in this buffer.
 
size_t getMappedBufferObjectSize () const
 Returns the size of the mapped area in bytes.
 
- Public Member Functions inherited from SoRefCounter
void ref () const
 Adds a reference to an instance.
 
void unref () const
 Removes a reference from an instance.
 
void unrefNoDelete () const
 unrefNoDelete() should be called when it is desired to decrement the reference count, but not delete the instance if this brings the reference count to zero.
 
int getRefCount () const
 Returns current reference count.
 
void lock () const
 lock this instance.
 
void unlock () const
 unlock this instance.
 
- Public Member Functions inherited from SoTypedObject
virtual SoType getTypeId () const =0
 Returns the type identifier for a specific instance.
 
SbBool isOfType (const SoType &type) const
 Returns TRUE if this object is of the type specified in type or is derived from that type.
 
template<typename TypedObjectClass >
SbBool isOfType () const
 Returns TRUE if this object is of the type of class TypedObjectClass or is derived from that class.

Constructor & Destructor Documentation

◆ SoInteropBufferObject()

SoInteropBufferObject::SoInteropBufferObject ( )

Default constructor.

Member Function Documentation

◆ clearInstance()

virtual void SoInteropBufferObject::clearInstance ( )
pure virtual

Free the memory allocated by the buffer object.

Implements SoBufferObject.

Implemented in SoGLBufferObject.

◆ createInstance()

virtual SoBufferObject * SoInteropBufferObject::createInstance ( ) const
pure virtual

Create a new buffer with the same properties as the current one.


The new instance will have the same context or device properties, but no memory is allocated.

Implements SoBufferObject.

Implemented in SoGLBufferObject.
