Class CMMFObject

class CMMFObject : public CBase;

Description

Defines an object to which a client may have a direct handle.

This class provides a way of identifying objects within the controller framework, and a means of passing commands to those objects.

Derivation

• CBase - Base class for all classes to be instantiated on the heap

• CMMFObject - Defines an object to which a client may have a direct handle

Members

Defined in CMMFObject:
CMMFObject(), Handle(), HandleRequest(), operator==(), ~CMMFObject()

Inherited from CBase:
Delete(), Extension_(), operator new()

IMPORT_C ~CMMFObject();

Description

Destructor.

IMPORT_C CMMFObject(TUid aInterfaceId);

Description

Constructor.

Parameters

TUid aInterfaceId The UID of the interface provided by this object.

IMPORT_C const TMMFMessageDestination &Handle();

Description

Returns the handle of the object.

Return value

const TMMFMessageDestination & The handle of this object.

IMPORT_C TBool operator==(const CMMFObject &aOther);

Description

Compares two CMMFObjects by comparing their handles.

Parameters

const CMMFObject &aOther The object to be compared with this object.

Return value

TBool A boolean indicating if the two CMMFObjects are the same. ETrue if they are the same, EFalse if the objects are different.

virtual void HandleRequest(TMMFMessage &aMessage)=0;

Description

Passes a message to the object to handle.

This is a pure virtual method to be implemented by concrete classes derived from this class.

The message passed in MUST be completed by the object; however, it can be copied to be completed at a later time, should some other asynchronous action need to occur first.

Parameters

TMMFMessage &aMessage The message to be handled. This MUST be completed by the object.
