|
24 * Resolves the MimeType and Resource type of the resource to match the file |
|
25 * name used in the Symbian side. This class is following the behavior of the |
|
26 * Symbian class XnInstallationHandler.cpp in ...Xuikon\UIManager\src\ |
|
27 * |
|
28 * In Symbian, MimeType is TDataType that has TBuf8 and TUid. The constructor |
|
29 * taking a descriptor of TDataType is as follows: |
|
30 * |
|
31 * If descriptor begins with "x-epoc/x-app", identifying data as a native |
|
32 * Symbian type, then the associated UID is set to the UID value which is |
|
33 * expected to follow the characters "x-epoc/x-app". If no sensible UID can be |
|
34 * extracted from the characters following: "x-epoc/x-app", then the associated |
|
35 * UID is set to KNullUid. |
|
36 * |
|
37 * Else Uid is set to KNullDesc and the descriptor is the descriptor given in |
|
38 * parameter. |
|
39 * |
|
40 * In ...Xuikon\UIManager\src\XnInstallationHandler.cpp |
|
41 * (ImportCompatibleResourcesL) MimeType is constructed using the Descriptor |
|
42 * that is parsed using file's name extension. Descriptors beginning with |
|
43 * "x-epoc/x-app" aren't used so TUid part is not implemented. Some of the types |
|
44 * are left empty in XnInstallationHandler.cpp. This represented as |
|
45 * EMPTY_MIME_TYPE |
|
46 * |
|
47 * Resource types are defined in Symbian side class XnResource.h |
