Constructor & Destructor Documentation

Command ( const std::string &  node,
const std::string &  sessionid,
Action  action,
DataForm form = 0 
)

Creates a Command object that can be used to perform the provided Action. This constructor is used best to continue execution of a multi stage command (for which the session ID must be known).

Parameters
nodeThe node (command) to perform the action on.
sessionidThe session ID of an already running adhoc command session.
actionThe action to perform.
formAn optional DataForm to include in the request. Will be deleted in Command's destructor.

Definition at line 95 of file adhoc.cpp.

Command ( const std::string &  node,
const std::string &  sessionid,
Status  status,
DataForm form = 0 
)

Creates a Command object that can be used to perform the provided Action. This constructor is used best to reply to an execute request.

Parameters
nodeThe node (command) to perform the action on.
sessionidThe (possibly newly created) session ID of the adhoc command session.
statusThe execution status.
formAn optional DataForm to include in the reply. Will be deleted in Command's destructor.

Definition at line 88 of file adhoc.cpp.

Command ( const std::string &  node,
const std::string &  sessionid,
Status  status,
Action  executeAction,
int  allowedActions = Complete,
DataForm form = 0 
)

Creates a Command object that can be used to perform the provided Action. This constructor is used best to reply to a multi stage command that is not yet completed (for which the session ID must be known).

Parameters
nodeThe node (command) to perform the action on.
sessionidThe (possibly newly created) session ID of the adhoc command session.
statusThe execution status.
executeActionThe action to execute.
allowedActionsAllowed reply actions.
formAn optional DataForm to include in the reply. Will be deleted in Command's destructor.

Definition at line 103 of file adhoc.cpp.

Command ( const std::string &  node,
Action  action,
DataForm form = 0 
)

Creates a Command object that can be used to perform the provided Action. This constructor is used best to execute the initial step of a command (single or multi stage).

Parameters
nodeThe node (command) to perform the action on.
actionThe action to perform.
formAn optional DataForm to include in the request. Will be deleted in Command's destructor.

Definition at line 81 of file adhoc.cpp.

Command ( const Tag tag = 0)

Creates a Command object from the given Tag.

Parameters
tagA <command> tag in the adhoc commands' namespace.

Definition at line 111 of file adhoc.cpp.

~Command ( )
virtual

Virtual destructor.

Definition at line 148 of file adhoc.cpp.
