        public boolean isCompatible​(SoDeviceContext name_11128)
        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.

      • isCurrent

        public void unbind()
        Unbind this context from the current thread.
      • isSharedWith

        public boolean isSharedWith​(SoDeviceContext context)
        Returns the current sharing state with passed context.
      • getSharedId

        public int getSharedId()
        Returns an id common to all compatible/shared contexts.
      • isSharable
