CCTTokenType Class Reference

class CCTTokenType : protected CBase

A token type.

This abstract class is instantiated using the ECom plug-in architecture for a particular token type. This adds a delayed destruction behaviour to MCTTokenType , which defines the majority of the interface.

This class uses protected inheritance from CBase so that clients cannot inadvertantly call delete on instances of it - they should call the Release() method instead.

Since: v7.0

ConstructL(TUid, const TDesC &, RFs)

IMPORT_C void	ConstructL	(	TUid	aUID,
			const TDesC &	aLabel,
			RFs	aFs
		)	[protected]

For 2 phase construction.

This function must be called by derived NewL() functions if and only if the class is being constructed without using ECom.

Parameters

TUid aUID
const TDesC & aLabel
RFs aFs

CreateTokenTypeLC(TUid)

Parameters

[inline]

Gets a file server session

Gets the file server session.

IncReferenceCount()

IMPORT_C void

IncReferenceCount

(

)

[protected]

Increments the reference count.

Must be called for every token created from this interface

Label()

IMPORT_C const TDesC &

Label

(

)

const [virtual]

Gets the label of the token type.

NewL(const CCTTokenTypeInfo &, RFs)

IMPORT_C CCTTokenType *	NewL	(	const CCTTokenTypeInfo &	aInfo,
			RFs	aFs
		)	[static]

Creates a CCTTokenType given its CCTTokenTypeInfo .

Static constructor function that uses the ECom plug-in architecture to load the actual implementation.

Parameters

const CCTTokenTypeInfo & aInfo	Information about the token type.
RFs aFs	An open file server session.

NewL(TUid, RFs)

IMPORT_C CCTTokenType *	NewL	(	TUid	aUID,
			RFs	aFs
		)	[static]

Creates a CCTTokenType given the UID of the token type.

Static constructor function that uses the ECom plug-in architecture to load the actual implementation.

Parameters

TUid aUID	The UID of the token type.
RFs aFs	An open file server session.

Release()

IMPORT_C void

Release

(

)

[virtual]

Releases the token type object.

To be called when you have finished with the object.

The API does not allow the destructor to be directly called as this object could remain in existence for longer to hold onto the ECom handle on the DLL; for instance it may not be deleted until all tokens and interfaces have also been released.

Type()

IMPORT_C TUid

Type

(

)

const [virtual]

Gets the UID of the token type.
