Reimplemented from Plugin.

inline const String& type () | ### type

[const]

Retrieve the type of the module

Returns: The module's type as String

void changed () | ### changed

Mark the driver statistics "dirty" therefore triggring a delayed status update.

inline unsigned int updateDelay () | ### updateDelay

[protected]

IDs of the installed relays

const char* messageName (int id) | ### messageName

[protected static]

Find the name of a specific Relay ID

Parameters:

id | RelayID of the message

Returns: Pointer to name of the message or NULL if not found

inline int relayId (const char* name) | ### relayId

[protected static]

Find the ID or a specific Relay name

Parameters:
