Ulogger::CPlugin Class Reference

class Ulogger::CPlugin : public CBase

ULogger is extensible through a plug-in framework that uses ECom for plug-in discovery. Deriving from this class means that all the ECom-specific logic is already provided for the plug-in implementer, out-of-the-box, leaving the plug-in code to deal with the domain-specific logic that the plug-in is supposed to implement only.

Among the plug-in types that are currently supported are output plug-ins (see class ULogger::MOutputPlugin in uloggeroutputplugin.h) and input plug-ins (see class ULogger::MInputPlugin in uloggerinputplugin.h).

Plug-ins must derive from this class in order to be compatible with ULogger.

Constructor & Destructor Documentation

~CPlugin()

~CPlugin

(

)

[inline, virtual]

Virtual destructor.

Member Functions Documentation

GetInterfaceL(TPluginInterface)

TAny *

GetInterfaceL

(

TPluginInterface

aInterfaceId

)

[pure virtual]

Return pointer to requested interface. If plug-in implements multiple interfaces, it should return pointer to proper interface trough this method.

Parameters

TPluginInterface aInterfaceId

Number of requested interface.

NewL(const TDesC8 &)

CPlugin *

NewL

(

const TDesC8 &

aCue

)

[static, inline]

Creates a CPlugin instance of the specified type and returns a pointer to it. The type is specified as the name of the ECom plug-in DLL (without the dll extension).

Parameters

const TDesC8 & aCue

a descriptor containing the name of the plug-in to be created

Member Enumerations Documentation
