CUri8 Class Reference

class CUri8 : public CBase

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.

Since: 6.0

Constructor & Destructor Documentation

CUri8(const TUriC8 &)

CUri8

(

const TUriC8 &

aNewUri

)

[private]

Constructor. First phase of two-phase construction method. Does non-allocating construction.

Since: 6.0

Parameters

const TUriC8 & aNewUri

The parsed uri component information from which to create the uri.

~CUri8()

IMPORT_C

~CUri8

(

ConstructL()

void

ConstructL

(

)

[private]

Second phase of two-phase construction method. Does any allocations required to fully construct the object.

Since: 6.0

Pre-condition: First phase of construction is complete.

Post-condition: The object is fully constructed and initialized.

CreateFileUriL(const TDesC &, TUint)

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

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>'.

Since: 9.1

Post-condition: A fully constructed and initialized file URI ( CUri8 ) object.

Parameters

const TDesC & aFullFileName	A reference to a fully qualified filename
TUint aFlags = 0	A flag to indicate if the file exists on a fixed drive or removable media drive. This is a TFileUriFlags value.

CreatePrivateFileUriL(const TDesC &, TDriveNumber, TInt)

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

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>'.

Since: 9.1

Post-condition: A fully constructed and initialized file URI ( CUri8 ) object.

Parameters

const TDesC & 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 = 0	A flag to indicate if the file exists on a fixed drive or removable media drive. This is a TFileUriFlags value.

FormUriL()

void

FormUriL

(

)

[private]

Forms the uri from the parsed uri information. A copy of the parsed uri is created. The parsed uri is changed to refer to the copy.

Since: 6.0

Pre-condition: The parsed uri information is set.

Post-condition: The uri buffer is updated with the parsed uri information.

InitializeFileUriComponentsL(const TDesC &, TDriveNumber, TUint)

void	InitializeFileUriComponentsL	(	const TDesC &	aFileName,
			TDriveNumber	aDrive,
			TUint	aFlags
		)	[private]

Initializes the file URI components (scheme, empty hostname and path).

It uses GenerateFileUriPathL() to generate a file Uri path using the filename and drive.

Since: 9.1

Pre-condition: Object fully constructed

Post-condition: The object is initialized with file URI components.

Parameters

const TDesC & aFileName	A reference to a filename
TDriveNumber aDrive	A drive number. This is a TFileUriFlags value.
TUint aFlags	A flag to indicate if the file exists on a fixed drive or removable media drive. This is a TFileUriFlags value.

NewL(const TUriC8 &)

IMPORT_C CUri8 *

NewL

(

const TUriC8 &

aUri

)

[static]

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.

Since: 6.0

Post-condition: A fully constructed and initialized CUri8 object.

Parameters

const TUriC8 & aUri

A reference to a parsed uri object.

NewLC(const TUriC8 &)

IMPORT_C CUri8 *

NewLC

(

const TUriC8 &

RemoveComponentL(TUriComponent)

IMPORT_C void

RemoveComponentL

(

TUriComponent

aComponent

)

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

CAUTION:

If host is removed, then userinfo and port components will also be removed.

Since: 6.0

Pre-condition: Object is fully constructed.

Post-condition: The uri is updated to exclude the specified component.

Parameters

TUriComponent aComponent

An enum specifying the component to be removed.

ResolveL(const TUriC8 &, const TUriC8 &)

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

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

CAUTION:

Ownership of created CUri8 object is transferred to the caller.

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

Since: 6.0

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

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.

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

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.

CAUTION:

The userinfo and port components can only be set if the host component is present. Setting these components without a host component present will have no effect on the uri.

Since: 6.0

Pre-condition: Object is fully constructed.

Post-condition: The uri has the specified component set to the new value. KErrArgument If aComponent goes out of range.

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.

Uri()
