All Superinterfaces:: DataInput

public interface ActiveMQBuffer extends DataInput

An ActiveMQBuffer wraps a Netty's ChannelBuffer and is used throughout ActiveMQ Artemis code base.

Instances of it can be obtained from ActiveMQBuffers factory.

Much of it derived from Netty ChannelBuffer by Trustin Lee

  the underlying Netty's ByteBuf

  Returns:
  
  the readerIndex of this buffer.
- readerIndex
  
  void readerIndex(int readerIndex)
  
  Sets the readerIndex of this buffer.
  
  Parameters:
  
  readerIndex - The reader's index
  
  Throws:
  
  IndexOutOfBoundsException - if the specified readerIndex is less than 0 or greater than this.writerIndex
- writerIndex
  
  int writerIndex()
  
  Returns the writerIndex of this buffer..
  
  Returns:
  
  the writerIndex of this buffer.
- writerIndex
  
  void writerIndex(int writerIndex)
  
  Sets the writerIndex of this buffer.
  
  Parameters:
  
  writerIndex - The writer's index
  
  Throws:
  
  IndexOutOfBoundsException - if the specified writerIndex is less than this.readerIndex or greater than this.capacity
- setIndex
  
  void setIndex(int readerIndex, int writerIndex)
  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 readerIndex(int) and 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, 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);
  Parameters:
  
  readerIndex - The reader's index
  
  writerIndex - The writer's index
  
  Throws:
  
  IndexOutOfBoundsException - if the specified readerIndex is less than 0, if the specified writerIndex is less than the specified readerIndex or if the specified writerIndex is greater than this.capacity

  src - The source buffer
  
  Throws:
  
  IndexOutOfBoundsException - if the specified index is less than 0 or if index + src.readableBytes is greater than this.capacity
