Constructor & Destructor Documentation

CFileBase(RFs &)

IMPORT_C

CFileBase

(

RFs &

anFs

)

[protected]

Protected default constructor.

Note that the class is intended only as an abstract base for other classes.

Parameters

RFs & anFs

File server session.

~CFileBase()

IMPORT_C

~CFileBase

(

)

[protected]

Destructor.

Frees resources prior to destruction of the object.

Member Functions Documentation

AbbreviatedPath()

IMPORT_C TPtrC

AbbreviatedPath

(

)

Gets the abbreviated path of the file or directory currently being processed.

The abbreviated path is its path relative to the top level directory specified in the operation.

CompleteOperationL()

void

CompleteOperationL

(

)

[protected, inline, virtual]

Called from RunL to perform tidy up after an operation.

CFileMan CFileBase::RunL

ConstructL()

IMPORT_C void

ConstructL

(

)

[protected]

Second phase constructor.

CurrentEntry()

IMPORT_C const TEntry &

CurrentEntry

(

)

Gets the entry currently being processed.

DoOperationL()

void

DoOperationL

(

)

[protected, pure virtual]

Called from RunL to perform the requested operation.

CFileMan CFileBase::RunL

FullPath()

IMPORT_C TPtrC

FullPath

(

)

Gets the full path of the file or directory currently being processed.

The full path includes the drive letter, path and filename.

GetLastError()

IMPORT_C TInt

GetLastError

(

)

Gets the latest error code returned during a CFileMan operation.

This function may be called from MFileManObserver::NotifyFileManEnded().

GetMoreInfoAboutError()

IMPORT_C TFileManError

GetMoreInfoAboutError

(

)

Gets additional information about the latest error returned during a CFileMan operation.

For example, if a rename fails, this function can be used to report whether the source or target name caused the problem. This information supplements that provided GetLastError().

CFileMan CFileBase::GetLastError()

RunInSeparateThreadL(TThreadFunction)

IMPORT_C void

RunInSeparateThreadL

(

TThreadFunction

aThreadFunction

)

[protected]

Creates a separate thread to run the command.

Parameters

TThreadFunction aThreadFunction

The thread function.

RunL()

IMPORT_C void

RunL

(

)

[protected]

Executes a command.

capability: Dependent the capabilities required by this method, of the abstract class CFileBase, will be dependent on and provided by the concrete-class implementation of the DoOperationL method

SetObserver(MFileManObserver *)

IMPORT_C void

SetObserver

(

MFileManObserver *

anObserver

)

Sets the observer.

Use this function to provide CFileMan with an MFileManObserver, or, if one already exists, to change the observer.

CFileMan MFileManObserver

Parameters

MFileManObserver * anObserver

File management observer.
