AsyncClient< T, Q >::RequestWriter Struct Reference

#include <evo/ioasync_client.h>

Inheritance diagram for AsyncClient< T, Q >::RequestWriter:

Detailed Description

template<class T, class Q>
struct evo::AsyncClient< T, Q >::RequestWriter

Used by the protocol implementation to write a request to an AsyncClient.

• This builds output request data and either writes it directly to the socket or prequeues it to be written by the event handler thread
• The request output size must be calculated in advance and passed to constructor
• Use inherited add() methods to write and build up the request data
• The destructor finishes the processes and sends and/or queues the request as appropriate
