      • transferTo

        long transferTo​(long position,
                        long count,
                        java.nio.channels.FileChannel target)
                 throws java.io.IOException
        Transfers bytes into the given file from this channel.
        Parameters:
        position - the position within the file from which the transfer is to begin
        count - the number of bytes to be transferred
        target - the file to write to
        Returns:
        the number of bytes (possibly 0) that were actually transferred
        Throws:
        java.io.IOException - if an I/O error occurs
      • transferTo

        long transferTo​(long count,
                        java.nio.ByteBuffer throughBuffer,
                        StreamSinkChannel target)
                 throws java.io.IOException
        Transfers bytes into the given channel target. On entry, throughBuffer will be cleared. On exit, the buffer will be flipped for emptying, and may possibly be empty or may contain data. If this method returns a value less than count, then the remaining data in throughBuffer may contain data read from this channel which must be written to target to complete the operation.
        Parameters:
        count - the number of bytes to be transferred
        throughBuffer - the buffer to copy through.
        target - the destination to write to
        Returns:
        the number of bytes (possibly 0) that were actually transferred, or -1 if the end of input was reached
        Throws:
        java.io.IOException - if an I/O error occurs
      • read

        int read​(java.nio.ByteBuffer dst)
          throws java.io.IOException
        Read a sequence of bytes from this conduit to the given buffer.
        Parameters:
        src - the buffer to fill with data from the conduit
        Returns:
        the number of bytes (possibly 0) that were actually transferred, or -1 if the end of input was reached or this conduit's SourceConduit.terminateReads() method was previously called
        Throws:
        java.io.IOException - if an error occurs
      • read

        long read​(java.nio.ByteBuffer[] dsts,
                  int offs,
                  int len)
           throws java.io.IOException
        Read a sequence of bytes from this conduit to the given buffers.
        Parameters:
        srcs - the buffers to fill with data from the conduit
        offs - the offset into the buffer array
        len - the number of buffers to fill
        Returns:
        the number of bytes (possibly 0) that were actually transferred, or -1 if the end of input was reached or this conduit's SourceConduit.terminateReads() method was previously called
        Throws:
        java.io.IOException - if an error occurs
