Class CObexNullObject

class CObexNullObject : public CObexBaseObject;

Description

Concrete OBEX object with NULL data representation. Use when only the headers of an object are required, and the data (if any) can safely be discarded.

Members

Defined in CObexNullObject:

• DataSize()
• GetData(TInt,TDes8 &)To return "NULL" data, we simply set aDes.Size = 0
• NewData(TInt,TDes8 &)In order to appear to consume the data, we don't set aDes.Size = 0
• NewL()Allocates and constructs a new null object.
• ResetData()

Inherited from CBase:

• Delete(CBase *)Deletes the specified object.
