Class StringLayout

    • Method Detail

      • writeObject

        public void writeObject​(DataBuffer<byte[]> buffer,
                                String value,
                                long index)
        Description copied from interface: DataLayout
        Writes a user value into the buffer at the given index after converting it to the buffer type.

        It is the responsibility of the implementors of this interface to write the converted value to the given buffer before this call returns, using the most appropriate method. For example, for a layout converting a BigInteger to a single long,

         @Override
         public void writeObject(LongDataBuffer buffer, BigInteger value, long index) {
           buffer.setLong(value.longValue(), index);
         }
         
        If a single user value scales over more than one buffer values, index indicates the starting position of the sequence to be written to the buffer.
        Specified by:
        writeObject in interface DataLayout<DataBuffer<byte[]>,​String>
        Parameters:
        buffer - the buffer to write to
        value - the value in the user type to convert and write
        index - index in the buffer where the converted value should be written
      • readObject

        public String readObject​(DataBuffer<byte[]> buffer,
                                 long index)
        Description copied from interface: DataLayout
        Reads n = scale() values from the buffer at the given index and return them as a single value in the user type.

        It is the responsibility of the implementors of this interface to read the value to be converted from the given buffer, using the most appropriate method. For example, for a layout that converting a single long to a BigInteger,

         @Override
         public BigInteger readObject(LongDataBuffer buffer, long index) {
           return BigInteger.valueOf(buffer.getLong(index));
         }
         
        If a single user value scales over more than one buffer values, index indicates the starting position of the sequence to be read from the buffer.
        Specified by:
        readObject in interface DataLayout<DataBuffer<byte[]>,​String>
        Parameters:
        buffer - the buffer to read from
        index - position of the buffer to read in the buffer
        Returns:
        the converted value
