      • getBuffer

        public static Buffer getBuffer​(int sizeBuffer,
                               boolean needsClearing)
        Obtains a Buffer of the specified size. If one cannot be found in the cache, a new one is allocated. If it needs to be clear(ed), the needsClearing flag should be set to true.
        Parameters:
        sizeBuffer - the size of the Buffer to be obtained
        needsClearing - whether the Buffer needs to be cleared
        Returns:
        the obtained Buffer

      • initializeBuffers

        public static void initializeBuffers​(int sizeBuffer,
                                     int nrBuffers)
        Initializes the buffer cache with the specified number of buffers of the specified size.
        Parameters:
        sizeBuffer - the size of the buffers
        nrBuffers - the number of buffers that need to be initialized
