Detailed Description

template<template< typename > typename Derived, SomeServerHandler HandlerType>
class web::impl::WsBase< Derived, HandlerType >

Web socket implementation. This class is the base class of the web socket session, it will handle the read and write operations.

The write operation is via a queue, each write operation of this session will be sent in order. The write operation also supports shared_ptr of string, so the caller can keep the string alive until it is sent. It is useful when we have multiple sessions sending the same content.

Template Parameters

Derived	The derived class
HandlerType	The handler type, will be called when a request is received.

Member Function Documentation

makeSubscriptionContext()

template<template< typename > typename Derived, SomeServerHandler HandlerType>

SubscriptionContextPtr web::impl::WsBase< Derived, HandlerType >::makeSubscriptionContext ( util::TagDecoratorFactory const & factory )

inlineoverridevirtual

Get the subscription context for this connection.

Parameters

factory

Tag TagDecoratorFactory to use to create the context.

Returns

The subscription context for this connection.

Implements web::ConnectionBase.

send() [1/2]

template<template< typename > typename Derived, SomeServerHandler HandlerType>

void web::impl::WsBase< Derived, HandlerType >::send ( std::shared_ptr< std::string > msg )

inlineoverridevirtual

Send a message to the client.

Parameters

msg	The message to send, it will keep the string alive until it is sent. It is useful when we have multiple session sending the same content. Be aware that the message length will not be added to the DOSGuard from this function.

Reimplemented from web::ConnectionBase.

send() [2/2]

template<template< typename > typename Derived, SomeServerHandler HandlerType>

void web::impl::WsBase< Derived, HandlerType >::send ( std::string && msg, http::status  )

inlineoverridevirtual

Send a message to the client.

Parameters

msg	The message to send Send this message to the client. The message length will be added to the DOSGuard If the DOSGuard is triggered, the message will be modified to include a warning

Implements web::ConnectionBase.
