Class CMMFDataSinkHolder

class CMMFDataSinkHolder : public CMMFObject;

Description

CMMFObject-derived class to wrap a Data Sink.

Allows a handle to be attributed to a data sink, so it can be removed from the controller and the client can send messages directly to it.

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.

• CMMFDataSinkHolder - CMMFObject-derived class to wrap a Data Sink.

Members

Defined in CMMFDataSinkHolder:

• CMMFDataSinkHolder(MDataSink &)Constructor.
• DataSink()Returns a reference to the data sink.
• HandleRequest(TMMFMessage &)Implementation of the pure virtual function inherited from CMMFObject.
• ~CMMFDataSinkHolder()Destructor.

Inherited from CBase:

• Delete(CBase *)Deletes the specified object.
• Extension_(TUint,TAny *&,TAny *)Extension function
• operator new(TUint)Allocates the object from the heap and then initialises its contents to binary z...
• operator new(TUint,TAny *)Initialises the object to binary zeroes.
• operator new(TUint,TLeave)Allocates the object from the heap and then initialises its contents to binary z...
• operator new(TUint,TLeave,TUint)Allocates the object from the heap and then initialises its contents to binary z...
• operator new(TUint,TUint)Allocates the object from the heap and then initialises its contents to binary z...

Inherited from CMMFObject:

• CMMFObject(TUid)Constructor.
• Handle()Returns the handle of the object.
• operator==(const CMMFObject &)Compares two CMMFObjects by comparing their handles.

IMPORT_C CMMFDataSinkHolder(MDataSink &aDataSink);

Description

Constructor.

Parameters

MDataSink &aDataSink The data sink to be wrapped.

IMPORT_C ~CMMFDataSinkHolder();

Description

Destructor.

Note: This deletes the data sink.

IMPORT_C MDataSink& DataSink();

Description

Returns a reference to the data sink.

Return value

MDataSink & The data sink.

IMPORT_C virtual void HandleRequest(TMMFMessage &aMessage);

Description

Implementation of the pure virtual function inherited from CMMFObject.

Passes the request directly to the data sink.

Parameters

TMMFMessage &aMessage The message to be handled.
