50 Declares a class as being non-sharable. |
|
51 |
|
52 If a class is non-sharable, then a class implemented in another DLL cannot |
|
53 derive (inherit) from that class. |
|
54 |
|
55 Declaring a class as non-sharable prevents the compiler from exporting compiler |
|
56 implementation-specific symbols, i.e. run-time type-information and virtual |
|
57 tables. This prevents classes in other DLLs from being able to derive from it. |
|
58 |
|
59 Note : |
|
60 - if a class is marked as non-sharable, then Symbian OS requires all |
|
61 classes that are derived from that class, and which are also implemented in the same DLL, |
|
62 to be declared as non-sharable. |
|
63 - by default, a class is sharable. |
|
64 |
|
65 The following code fragment shows how a non-sharable class is declared. |
|
66 |
|
67 @code |
|
68 NONSHARABLE_CLASS(CMyClass) : public CBase |
