Interface ConstantHandler

    • Method Detail

      • moveToConstantSpace

        long moveToConstantSpace​(DataBuffer dataBuffer)
        If specific hardware supports dedicated constant memory, this method forces DataBuffer passed in to be moved to that constant memory. PLEASE NOTE: This method implementation is hardware-dependant.
        Parameters:
        dataBuffer -
        Returns:

      • relocateConstantSpace

        DataBuffer relocateConstantSpace​(DataBuffer dataBuffer)
        PLEASE NOTE: This method implementation is hardware-dependant. PLEASE NOTE: This method does NOT allow concurrent use of any array
        Parameters:
        dataBuffer -
        Returns:

      • getConstantBuffer

        DataBuffer getConstantBuffer​(boolean[] array,
                             DataType dataType)
        This method returns DataBuffer with constant equal to input array. PLEASE NOTE: This method assumes that you'll never ever change values within result DataBuffer
        Parameters:
        array -
        Returns:

      • getConstantBuffer

        DataBuffer getConstantBuffer​(long[] array,
                             DataType dataType)
        This method returns DataBuffer with constant equal to input array. PLEASE NOTE: This method assumes that you'll never ever change values within result DataBuffer
        Parameters:
        array -
        Returns:

      • getConstantBuffer

        DataBuffer getConstantBuffer​(double[] array,
                             DataType dataType)
        This method returns DataBuffer with contant equal to input array. PLEASE NOTE: This method assumes that you'll never ever change values within result DataBuffer
        Parameters:
        array -
        Returns:
