Class CUri8

class CUri8 : public CBase;

Description

Dependencies : CBase, TUriC8. Comments : Provides modifying functionality on the components of a uri object, as defined in RFC2396. There are 5 components; scheme. authority, path, query and fragment.

The object holds parsed uri information. It is owning. It uses 8-bit descriptors.

The functionality provided by this API allows the uri components to be set or removed from this parsed uri. Also, it provides a reference to TUriC8 object so that the non-modifying functionality can be used.

IMPORT_C static CUri8* NewL(const TUriC8 &aUri);

Description

Static factory constructor. Uses two phase construction and leaves nothing on the CleanupStack. Creates a uri object which is a copy of the input parameter aUri.

Post-Condition

A fully constructed and initialized CUri8 object.

Parameters

const TUriC8 &aUri A reference to a parsed uri object.

Return value

CUri8 * A pointer to the newly created CUri8 object.

IMPORT_C static CUri8* NewLC(const TUriC8 &aUri);

Description

Static factory constructor. Uses two phase construction and leaves a pointer to created object on the CleanupStack. Creates a uri object which is a copy of the input parameter aUri.

Post-Condition

A fully constructed and initialized CUri8 object.

Parameters

const TUriC8 &aUri A reference to a parsed uri object.

Return value

CUri8 * A pointer to the newly created CUri8 object.

IMPORT_C static CUri8* NewL();

Description

Static factory constructor. Uses two phase construction and leaves nothing on the CleanupStack. Creates a uri object which is empty.

Post-Condition

A fully constructed and initialized CUri8 object.

Return value

CUri8 * A pointer to the newly created CUri8 object.

IMPORT_C static CUri8* NewLC();

Description

Static factory constructor. Uses two phase construction and leaves a pointer to created object on the CleanupStack. Creates a uri object which is empty.

Post-Condition

A fully constructed and initialized CUri8 object.

Return value

CUri8 * A pointer to the newly created CUri8 object.

IMPORT_C ~CUri8();

Description

Destructor.

IMPORT_C static CUri8* CreateFileUriL(const TDesC &aFullFileName, TUint aFlags=0);

Description

Allocates and constructs a file URI object for a specified file.

• If the file exists on a fixed drive, then the file URI takes the form: 'file:///<drive-letter>/<filepath including filename>'.

• If the file exists on a removable media drive, then the file URI takes the form: 'file:///ext-media/<filepath including filename>'.

Post-Condition

A fully constructed and initialized file URI (CUri8) object.

Parameters

const TDesC16 &aFullFileName A reference to a fully qualified filename TUint aFlags A flag to indicate if the file exists on a fixed drive or removable media drive. This is a TFileUriFlags value.

Return value

CUri8 * A pointer to the newly created file URI (CUri8) object.

IMPORT_C static CUri8* CreatePrivateFileUriL(const TDesC &aRelativeFileName, TDriveNumber aDrive, TInt aFlags=0);

Description

Allocates and constructs a file URI object for a file that is private to the application.

• If the file exists on a fixed drive, then the file URI takes the form 'file:///private/<drive-letter>/<filepath including filename>'.

• If the file exists on a removable media drive, then the file URI takes the form 'file:///private/ext-media/<filepath including filename>'.

Post-Condition

A fully constructed and initialized file URI (CUri8) object.

Parameters

const TDesC16 &aRelativeFileName A reference to the filename relative to the application's private directory. TDriveNumber aDrive Drive number, if the private file stored on fixed drive, otherwise not used This is a TDriveNumber value TInt aFlags A flag to indicate if the file exists on a fixed drive or removable media drive. This is a TFileUriFlags value.

Return value

CUri8 * A pointer to the newly created file URI (CUri8) object.

IMPORT_C static CUri8* ResolveL(const TUriC8 &aBaseUri, const TUriC8 &aRefUri);

Pre-Condition

The base uri must have an absolute or empty path, otherwise will leave with KUriErrBadBasePath.

Description

Static factory constructor. This creates a CUri8 object that is an absolute uri resulting from a reference uri being resolved against a base uri.

Post-Condition

A fully constructed and initialized CUri8 object.

Parameters

const TUriC8 &aBaseUri A referece to the parsed base uri. const TUriC8 &aRefUri A referece to the parsed reference uri.

Return value

CUri8 * A pointer to the newly created CUri8 object.

Leave codes

KUriErrBadBasePath if the base path is not an absolute path and not empty.

IMPORT_C const TUriC8& Uri() const;

Description

Provides a reference to the parsed uri. Allows access to the non-modifying API for TUriC8.

Return value

const TUriC8 & A const reference to the parsed uri object.

IMPORT_C void SetComponentL(const TDesC8 &aData, TUriComponent aComponent);

Pre-Condition

Object is fully constructed.

Description

Intended Usage : Sets the specified component in the uri. The component is set to the value given in the argument aData. If the specified component already exists then it is replaced with the new value.

Post-Condition

The uri has the specified component set to the new value.

Parameters

const TDesC8 &aData A descriptor pointer to the new value for the uri component. TUriComponent aComponent An enum specifying the component to be set.

IMPORT_C void RemoveComponentL(TUriComponent aComponent);

Pre-Condition

Object is fully constructed.

Description

Removes the specified component from the uri. If the component does not exist then this function does nothing.

Post-Condition

The uri is updated to exclude the specified component.

Parameters

TUriComponent aComponent An enum specifying the component to be removed.
