Poco::Redis

class Command

File Information

Library: Redis
Package: Redis
Header: Poco/Redis/Command.h

Description

Helper class for creating commands. This class contains factory methods for commonly used Redis commands.

There are two ways of building commands:

  1. Use this class and the factory methods
  2. Use the Array or Command class and build the command using the add method or << operator.

For example: 

Command cmd = Command::set("mykey", "Hello");

is the same as: 

Array cmd;
cmd << "SET" << "mykey" << "Hello";
