14 // Implementation of the TEComResolverParams class. |
|
15 // Provide the inline implementation of TEComResolverParams |
|
16 // TEComResolverParams allows the user to define the characteristics |
|
17 // of the Interface Implementation plugin to be found. |
|
18 // Default constructor of TEComResolverParams. It creates an empty uninitialized |
|
19 // resolver parameter object. Such an object maybe used in calls to REComSession |
|
20 // CreateImplementationL() and ListImplementationsL() methods when no specific |
|
21 // matching or filtering is required i.e. default type matching will be used. |

88 plugin". |
