      • clear

        public void clear()
        Description copied from interface: ActiveMQBuffer
        Sets the readerIndex and writerIndex of this buffer to 0. This method is identical to setIndex(0, 0).

        Please note that the behavior of this method is different from that of NIO buffer, which sets the limit to the capacity of the buffer.

        Specified by:
        clear in interface ActiveMQBuffer
        Overrides:
        clear in class ChannelBufferWrapper

      • setIndex

        public void setIndex​(int readerIndex,
                     int writerIndex)
        Description copied from interface: ActiveMQBuffer
        Sets the readerIndex and writerIndex of this buffer in one shot. This method is useful when you have to worry about the invocation order of ActiveMQBuffer.readerIndex(int) and ActiveMQBuffer.writerIndex(int) methods. For example, the following code will fail: 
         // Create a buffer whose readerIndex, writerIndex and capacity are
 // 0, 0 and 8 respectively.
 ChannelBuffer buf = ChannelBuffers.buffer(8);

 // IndexOutOfBoundsException is thrown because the specified
 // readerIndex (2) cannot be greater than the current writerIndex (0).
 buf.readerIndex(2);
 buf.writerIndex(4);
        The following code will also fail: 
         // Create a buffer whose readerIndex, writerIndex and capacity are
 // 0, 8 and 8 respectively.
 ChannelBuffer buf = ChannelBuffers.wrappedBuffer(new byte[8]);

 // readerIndex becomes 8.
 buf.readLong();

 // IndexOutOfBoundsException is thrown because the specified
 // writerIndex (4) cannot be less than the current readerIndex (8).
 buf.writerIndex(4);
 buf.readerIndex(2);
        By contrast, ActiveMQBuffer.setIndex(int, int) guarantees that it never throws an IndexOutOfBoundsException as long as the specified indexes meet basic constraints, regardless what the current index values of the buffer are: 
         // No matter what the current state of the buffer is, the following
 // call always succeeds as long as the capacity of the buffer is not
 // less than 4.
 buf.setIndex(2, 4);
