Class org.jboss.netty.buffer.ChannelBuffer

Examples of org.jboss.netty.buffer.ChannelBuffer.writeShort()

org.jboss.netty.buffer.ChannelBuffer.writeShort()
Sets the specified 16-bit short integer at the current {@code writerIndex} and increases the {@code writerIndex} by {@code 2}in this buffer. @throws IndexOutOfBoundsException if {@code this.writableBytes} is less than {@code 2}
