Detailed Description

Command

Use the Command object in combination with a CommandList object to maintain a list of functions that can be invoked as a result of processing a request.

Member Function Documentation

check()

bool core::Command::check ( std::string  request )

virtual

Implement check method to provide a special check rule upon the request to see if the command should be processed.

The default rule is to verify that the first token in the request string matches the name given on the registration of the command to the CommandList. This can be overridden by implementing the check() method to perform the test and return the condition of the command.

Parameters

request

The request passed to the parser to check the rule.

Returns

Return true to execute the command. Returning false will cause no action on this command.

output()

void core::Command::output ( Session *  session )

virtual

Specify the output that will occur to the specified session.

Parameters

session

The session that will receive the output.

processCommand()

int core::Command::processCommand ( std::string  request, TCPSession *  session, std::stringstream &  data  )

virtual

This method is used to implement the functionality of the requested command. This pure virtual function must be implemented in your inheriting object.

Parameters

request	The request that was entered by the user to invoke this command.
session	Specify the requesting session so that the execution of the command process can return its output to the session.

Returns

Returns 0 if execution of the command was successful. Otherwise returns a non-zero value indicating an error condition.

Reimplemented in core::CommandList, core::EPoll, and core::TCPServer.

setName()

void core::Command::setName

(

std::string

name

)

Set the name of this command used in default rule checking during request parsing. NOTE: You do not need to call this under normal conditions as adding a Command to a CommandList using the add() method contains a parameter to pass the name of the Command.

Parameters

name	Specify the name of this command for default parsing.
