| IMPORT_C CDir * | NewL() |
Array of directory entries that has been read into memory from the file system.
It can be read and sorted by user programs, but cannot be created by them.
| IMPORT_C | ~CDir | ( | ) | [virtual] |
Destructor.
Frees all resources owned by the object, prior to its destruction.
| IMPORT_C void | AddL | ( | const TEntry & | anEntry | ) | [protected] |
Adds the specified entry to the directory.
Note that the function can leave.
| Parameter | Description |
|---|---|
| anEntry | The directory entry to be added. |
| IMPORT_C void | Compress | ( | ) | [protected] |
Compresses the directory.
This has the effect of potentially reducing the ammount of storage space required on the media for that directory and the files it contains. Some files are already compressed and will not compress further.
A potential side effect of compression is that each file is required to be uncompressed prior to use, generally increasing the time and processing cycles required to access that file.
| IMPORT_C TInt | Count | ( | ) | const |
Gets the number of entries in the array of directory entries.
Returns: The number of entries in the array.
Copies all directory entries from this directory array, and adds them to a new directory array.
The directory entries in this array can be deleted.
Note that the function can leave.
| Parameter | Description |
|---|---|
| aRemove | If ETrue, the directory entries in this array are to be deleted after extraction; if EFalse, the directory entries are not to be deleted. |
| aDir | On return, a pointer to a CDir object containing the extracted directory entries. |
| IMPORT_C CDir * | NewL | ( | ) | [protected, static] |
Allocates and constructs a directory object.
This function is protected, which prevents objects of this class from being directly constructed.
Returns: A pointer to the newly created object.
Sorts the array of directory entries.
See also: TEntryKey
| Parameter | Description |
|---|---|
| aEntrySortKey | A set of flags describing how the directory entries are to be sorted. The set of flags is defined by TEntryKey. |
Returns: KErrNone, if successful, otherwise one of the other system-wide error codes.
