invocation order of ChannelBuffer.readerIndex(int)
and ChannelBuffer.writerIndex(int)
methods. For example, the following code will fail:
// Create a buffer whose readerIndex, writerIndex and capacity are // 0, 0 and 8 respectively.The following code will also fail: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);
// Create a buffer whose readerIndex, writerIndex and capacity are // 0, 8 and 8 respectively.By contrast, this method guarantees that it never throws anChannelBuffer
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);
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);
