|
59 Declares a class as being non-sharable. |
|
60 |
|
61 If a class is non-sharable, then a class implemented in another DLL cannot |
|
62 derive (inherit) from that class. |
|
63 |
|
64 Declaring a class as non-sharable prevents the compiler from exporting compiler |
|
65 implementation-specific symbols, i.e. run-time type-information and virtual |
|
66 tables. This prevents classes in other DLLs from being able to derive from it. |
|
67 |
|
68 Note : |
|
69 - if a class is marked as non-sharable, then Symbian OS requires all |
|
70 classes that are derived from that class, and which are also implemented in the same DLL, |
|
71 to be declared as non-sharable. |
|
72 - by default, a class is sharable. |
|
73 |
|
74 The following code fragment shows how a non-sharable class is declared. |
|
75 |
|
76 @code |
|
77 NONSHARABLE_CLASS(CMyClass) : public CBase |
