      • pour

        public static int pour​(java.nio.ByteBuffer source,
                       java.nio.ByteBuffer destination)
        Returns:
        number of bytes poured

      • pourArrayToBuffer

        public static int pourArrayToBuffer​(byte[] source,
                                    int offset,
                                    int sizeRequested,
                                    java.nio.ByteBuffer destination)
        Assumes destination is ready to be written.
        Returns:
        number of bytes poured which may be fewer than sizeRequested if destination has insufficient remaining

      • pourAll

        public static int pourAll​(java.nio.ByteBuffer source,
                          TransportInput destinationTransportInput)
                   throws TransportException
        Pours the contents of source into destinationTransportInput, calling the TransportInput many times if necessary. If the TransportInput returns a TransportResult other than ok, data may remain in source.
        Throws:
        TransportException

      • pourBufferToArray

        public static int pourBufferToArray​(java.nio.ByteBuffer source,
                                    byte[] destination,
                                    int offset,
                                    int sizeRequested)
        Assumes source is ready to be read.
        Returns:
        number of bytes poured which may be fewer than sizeRequested if source has insufficient remaining
