/** |

Declares a class as being non-sharable. |
|
47 |
||
48 |
If a class is non-sharable, then a class implemented in another DLL cannot |
|
49 |
derive (inherit) from that class. |
|
50 |
||
51 |
Declaring a class as non-sharable prevents the compiler from exporting compiler |
|
52 |
implementation-specific symbols, i.e. run-time type-information and virtual |
|
53 |
tables. This prevents classes in other DLLs from being able to derive from it. |
|
54 |
||
55 |
Note : |
|
56 |
- if a class is marked as non-sharable, then Symbian OS requires all |
|
57 |
classes that are derived from that class, and which are also implemented in the same DLL, |
|
58 |
to be declared as non-sharable. |
|
59 |
- by default, a class is sharable. |
|
60 |
||
61 |
The following code fragment shows how a non-sharable class is declared. |
|
62 |
@code |
|
63 |
NONSHARABLE_CLASS(CMyClass) : public CBase |
|
64 |

|

private : |

72 |
