Examples of java.nio.CharBuffer.arrayOffset()

java.nio.CharBuffer.arrayOffset()
Returns the offset of the char array which this buffer is based on, if there's one.
The offset is the index of the array corresponds to the zero position of the buffer.
@return The offset of the char array which this buffer is based on @exception ReadOnlyBufferException If this buffer is based on an array, but it is readonly @exception UnsupportedOperationException If this buffer is not based on an array

        // new String(byte[], int, int, Charset) takes a defensive copy of the
        // entire byte array. This is expensive if only a small subset of the
        // bytes will be used. The code below is from Apache Harmony.
        CharBuffer cb;
        cb = charset.decode(ByteBuffer.wrap(buff, start, end-start));
        return new String(cb.array(), cb.arrayOffset(), cb.length());
