      long getLength()
      Returns the number of bytes currently stored in this object.
      java.io.OutputStream getOutputStream()
      Returns an output stream which can be used to write to the store.

      Returns an array of byte buffers containing the bytes written to this store.
    • Method Detail

      • getOutputStream

        java.io.OutputStream getOutputStream()
        Returns an output stream which can be used to write to the store. May be called multiple times; always returns the same object. Note that this is not in general buffered - it is the responsibility of the user to take steps like wrapping it in a BufferedOutputStream for efficiency if required.
        Returns:
        data sink stream
      • getLength

        long getLength()
        Returns the number of bytes currently stored in this object.
        Returns:
        byte count
      • copy

        void copy​(java.io.OutputStream out)
           throws java.io.IOException
        Takes all the data written so far into this store's sink stream and copies it to a destination stream. The output stream is not closed.
        Parameters:
        out - data destination stream
        Throws:
        java.io.IOException
      • toByteBuffers

        java.nio.ByteBuffer[] toByteBuffers()
                                     throws java.io.IOException
        Returns an array of byte buffers containing the bytes written to this store. The stored bytes are all of the bytes from the first buffer in the returned array, followed by all in the second, etc. In many cases the returned array will, and probably should, contain a single buffer, but if the written byte count exceeds Integer.MAX_VALUE, more than one will be required. The limit of each buffer indicates the number of bytes it contains.

        Usual usage will be to write all data, then call this method once; this model may affect implementation decisions about efficiency.

        Returns:
        byte buffer containing bytes written
        Throws:
        java.io.IOException - if there is an I/O error
      • close

        void close()
        Tidies up. Should be called when the data in this object is no longer required. This object may no longer be usable following a call to this method.
