Redis Client

cpp_redis::redis_client is the class providing communication with a Redis server.
It is meant to be used for sending commands to the remote server and receiving its replies.
The client support asynchronous requests, as well as synchronous ones. Moreover, commands pipelining is supported.
void connect(const std::string& host = "127.0.0.1", unsigned int port = 6379, const disconnection_handler& handler = nullptr)Description
Connects to the Redis Server. Connection is done synchronously. Throws redis_error in the case of a failure or if the client is already connected.
Also, sets the disconnection handler which is called whenever a disconnection has occurred.
Disconnection handler is an std::function<void(redis_client&)>.
Parameters
| Type | Name | Description |
|---|---|---|
| const std::string& | host | Host to be connected to |
| unsigned int | port | Port of the hot to be connected to. If port is 0, host will be considered as a path to a unix socket and port will be ignored. |
| const disconnection_handler& | handler | Callback to be called on client disconnection |
Return Value
None.
void disconnect(void)Description
Disconnects client from remote host. Throws redis_error if the client is not connected to any server.
Parameters
None.
Return value
None.
bool is_connected(void)Description
Returns whether the client is connected or not.
Parameters
None.
Return value
Whether the client is connected or not.
redis_client& send(const std::vector<std::string>& redis_cmd, const reply_callback& callback = nullptr)Description
Sends a command and sets the callback which has to be called when the reply has been received.
If nullptr is passed as callback, command is executed and no callback will be called.
Reply callback is an std::function<void(reply&)>.
The command is not effectively sent immediately but stored in an internal buffer until commit() is called.
Parameters
| Type | Name | Description |
|---|---|---|
| const std::vectorstd::string& | redis_cmd | Vector of std::string containing the command to be executed. Each item in the vector is supposed to be one word of the command like { "GET", "hello" }
|
| const reply_callback& | callback | Callback to be executed once reply has been received by the redis server |
Return value
Reference to the current instance of the redis_client.
redis_client& commit(void)Description
Sends all the commands that have been stored by calling send() since the last commit() call to the redis server.
That is, pipelining is supported in a very simple and efficient way: client.send(...).send(...).send(...).commit() will send the 3 commands at once (instead of sending 3 network requests, one for each command, as it would have been done without pipelining).
Pipelined commands are always removed from the buffer, even in the case of an error (for example, calling commit while the client is not connected, something that throws an exception).
commit() works asynchronously: it returns immediately after sending the queued requests and replies are processed asynchronously.
Another version of commit(), sync_commit(), provides a synchronous version of the commit function. It sends all the requests and waits that all replies are received and that all the callbacks are executed before returning.
sync_commit() also support timeout, using std::chrono: client.sync_commit(std::chrono::milliseconds(100));.
Parameters
None.
Return value
Reference to the current instance of the redis_client.
redis_client& set_callback_runner(const std::function<void(reply&, const reply_callback_t& callback)>& callback_runner)Description
set_callback_runner is a method that allows you to set a callback which is executed whenever a reply callback is going to be executed and allows you to run this reply callback by yourself.
This can be useful in the case you need to execute pre and after callback hooks.
set_callback_runner sets the callback runner globally to the redis_client instance, meaning that all replies callbacks will have to be run by the callback_runner since the redis_client will not run any callbacks by himself.
Basically, without callback_runner, the workflow is the following:
[Send Command]->[Commit]->[Receive Reply]->[Execute Callback]
With callback_runner, the workflow is the following:
[Send Command]->[Commit]->[Receive Reply]->[Execute Callback Runner]
callback runner takes as a parameter the reply and the callback associated to that reply and meant to be called.
Parameters
| Type | Name | Description |
|---|---|---|
| const std::function<void(reply&, const reply_callback_t& callback)>& | callback_runner | Callback to be executed once each command reply is received |
Return value
Reference to the current instance of the redis_client.
The following list contains all the supported commands. If a command is missing or that the method to call that command is not convenient, please consider using the send() method directly.
All the following member functions are wrappers for the send() function to provide more code clarity.
