CVersitParser Class Reference

class CVersitParser : public CBase

A generic Versit parser.

Provides generic functions which implement behaviour common to both vCalendar and vCard parsers. For instance:

  • adding/retrieving properties and sub-entities to/from an existing entity.

  • encoding and character set conversion capabilities.

Although this is not an abstract class, in practice you would create and use objects of a derived class instead (CParserVCal or CParserVCard), as these provide additional functionality needed for parsing vCalendars and vCards.

Note: a flag used in the class constructor indicates whether the entity needs a version property. The version property will be inserted at the start of the array of properties for the entity, and specifies the version of the vCard/vCalendar specification used by the data of this particular vCard/vCalendar. The versions that are currently supported are vCard v2.1 and vCalendar v1.0.

A typical vCard looks like this:

BEGIN VCARD

VERSION 2.1 ...

END VCARD

Note: if you are sequentially creating and destroying multiple parsers, a major performance improvement may be achieved by using thread local storage to store an instance of CVersitUnicodeUtils which persists and can be used by all of the parsers.

See CVersitTlsData for more details.

Constructor & Destructor Documentation

CVersitParser(TUint)

IMPORT_CCVersitParser(TUintaFlags)

The first phase constructor for a Versit parser.

Sets the default encoding to Versit::ENoEncoding and the default character set to Versit::EUSAsciiCharSet.

Note: this function is called by the CParserVCal and CParserVCard constructors. It should only be called directly by a user if creating a new parser

Parameters

TUint aFlagsThe flag to indicate whether this entity needs a version property. The possible values for this flag are given in the TVersitParserFlags enumeration. If a version property is needed, one will be created and appended to the start of the array of properties.

~CVersitParser()

IMPORT_C~CVersitParser()

Frees all resources owned by the object, prior to its destruction.

Member Functions Documentation

AddEntityL(CVersitParser *)

IMPORT_C voidAddEntityL(CVersitParser *aEntity)

Adds a sub-entity (e.g. a to-do, event or a nested vCard) to the current entity.

Sets the default encoding and character set to the default ones of the current Versit parser, then adds the entity to the array of entities owned by the parser.

Note: This function may be used when building up a Versit parser object from a client application.

Called by ParseEntityL().

Parameters

CVersitParser * aEntityThe entity to be added into the array of entities. Ownership of aEntity is taken at beginning of the function.

AddPropertyL(CParserProperty *, TBool)

IMPORT_C voidAddPropertyL(CParserProperty *aProperty,
TBoolaInternalizing = EFalse
)

Appends a property to the current entity's array of properties.

This function may be used when building up a Versit parser object from a client application. It is not called internally.

Parameters

CParserProperty * aPropertyPointer to the property to add to the entity.
TBool aInternalizing = EFalseThis parameter is used to distinguish between reading an entity from a stream or file (i.e. internalising), in which case the argument should have a value of ETrue, and building an entity "by hand" (e.g. creating a vCard in the Contacts application), in which case the argument should have a value of EFalse.

AdjustAllPropertyDateTimesToMachineLocalL()

IMPORT_C voidAdjustAllPropertyDateTimesToMachineLocalL()

AnalysesEncodingCharset(CArrayPtr< CParserParam > *)

IMPORT_C voidAnalysesEncodingCharset(CArrayPtr< CParserParam > *aArrayOfParams)[protected]

Parameters

CArrayPtr< CParserParam > * aArrayOfParams

AppendBeginL()

IMPORT_C voidAppendBeginL()[protected]

ArrayOfEntities(TBool)

IMPORT_C CArrayPtr< CVersitParser > *ArrayOfEntities(TBoolaTakeOwnership = ETrue)

Gets the current entity's array of sub-entities.

Note: the current entity may be a top level entity, or may itself be a sub-entity.

Parameters

TBool aTakeOwnership = ETrueIf ETrue, the calling code takes ownership of the array; the array of entities owned by the current entity is then deleted. If EFalse, ownership remains with the Versit parser.

ArrayOfProperties(TBool)

IMPORT_C CArrayPtr< CParserProperty > *ArrayOfProperties(TBoolaTakeOwnership = ETrue)

Gets the current entity's array of properties.

Parameters

TBool aTakeOwnership = ETrueIf ETrue, the calling code takes ownership of the array; the entity's array of properties is then deleted . If EFalse, ownership remains with the entity.

BufPtr()

ClearSupportsVersion()

voidClearSupportsVersion()[protected, inline]

ConstructL()

IMPORT_C voidConstructL()

The second phase constructor for a Versit parser.

Stores a pointer to a CVersitTlsData (thread local storage data class). This is used to allow an instance of CVersitUnicodeUtils to be shared by all co-existing parsers, which provides a major performance improvement.

Called by the CParserVCal and CParserVCard constructors.

Should only be called directly by a user if creating a new parser.

ConvertAllPropertyDateTimesToMachineLocalL(const TTimeIntervalSeconds &, const CVersitDaylight *)

IMPORT_C voidConvertAllPropertyDateTimesToMachineLocalL(const TTimeIntervalSeconds &aIncrement,
const CVersitDaylight *aDaylight
)[virtual]

Converts all date/time property values contained in the current entity's array of properties into machine local values.

This conversion is needed because of differences in universal and local times due to time zones and daylight savings (seasonal time shifts).

First, all of the date/times are converted to universal time, if they are not already:

If daylight saving is in effect then the daylight savings rule (held in the aDaylight parameter) will be used to compensate for differences between universal and local times due to both time zones and the daylight saving. Otherwise, the aIncrement parameter is used to compensate for any difference due to time zones alone.

Then, these universal time values are converted into machine local times by adding the universal time offset for the machine's locale.

since 9.1

Parameters

const TTimeIntervalSeconds & aIncrementA time interval in seconds which represents the negative of the time zone of the originating machine. For instance, if the time zone is +04:30, aIncrement should be set to -04:30.
const CVersitDaylight * aDaylightPointer to the specification for daylight saving. If the date/time value is within the period for daylight saving, the value is modified by the daylight saving offset (which accounts for both the time zone and daylight saving rule).

The presence of this function means that the standard templated operator<<() (defined in s32strm.h) is available to externalise objects of this class.

This virtual function serves as a base function for derived classes to externalise an entity.

Parameters

RWriteStream & aStreamStream to which the entity should be externalised.

LoadBinaryValuesFromFilesL()

IMPORT_C TIntLoadBinaryValuesFromFilesL()

Loads all files represented by URI property values and sets the binary data contained in the files to be the property values instead of the URIs.

For every property in the parser, if its value is a URI containing file:// followed by a path and filename, then the file is opened and the binary data it contains is read into a CParserPropertyValueBinary object. This replaces the URI as the property value. The function also operates on any agents in the vCard that contain URI property values.

The function creates its own file server session, which is needed to open the files. It leaves if there is a problem opening any of the files.

LoadBinaryValuesFromFilesL(RFs &)

IMPORT_C TIntLoadBinaryValuesFromFilesL(RFs &aFileSession)

Loads all files represented by URI property values and sets the binary data contained in the files to be the property values instead of the URIs.

For every property in the parser, if its value is a URI containing file:// followed by a path and filename, then the file is opened and the binary data it contains is read into a CParserPropertyValueBinary object. This replaces the URI as the property value. The function also operates on any agents in the vCard that contain URI property values.

The function uses the file server session supplied, which is needed to open the files. It leaves if there is a problem opening any of the files.

Parameters

RFs & aFileSessionThe file server session used to open the files.

RecognizeEntityName()

IMPORT_C TIntRecognizeEntityName()const [virtual]

Tests the current entity to see if it is a vEvent or vTodo.

This function is virtual. Actual testing only occurs in derived classes which implement this function.

RecognizeToken(const TDesC8 &)

IMPORT_C TUidRecognizeToken(const TDesC8 &aToken)const [virtual]

Returns a UID for the specified token.

This function only recognizes generic Versit tokens. For example, if aToken contains the property name KVersitTokenBEGIN, the function returns KVersitTokenBeginUid. More specific recognition should occur in derived classes which implement this function, using this as the base recogniser.

Parameters

const TDesC8 & aTokenThe token to be recognized.

RestoreLineCodingDetailsToDefault()

IMPORT_C voidRestoreLineCodingDetailsToDefault()[protected]

SaveBinaryValuesToFilesL(TInt, const TDesC &)

IMPORT_C TIntSaveBinaryValuesToFilesL(TIntaSizeThreshold,
const TDesC &aPath
)

Saves all binary property values larger than a specified threshold to files, and sets each property value to be a URI representing the file, rather than the binary data iself.

The files are created in the folder identified by aPath, and are assigned unique filenames that consist of the property name and some random numbers.

Each new URI property value is prefixed with file:// and contains the path and filename of the file created.

If a vCard contains any agent property values and if they contain binary data whose size exceeds the threshold, these property values are replaced with URI property values.

The function sets up its own file server session, which is needed to create the files. It leaves if there is a problem creating any of the files.

Parameters

TInt aSizeThresholdThe threshold number of bytes for the binary data, above which the binary data is stored in a file.
const TDesC & aPathThe path identifying the location in which the files are created. This must not be greater than 240 characters long or the function leaves with KErrArgument. If it doesn't end in a slash, then one is appended.

SaveBinaryValuesToFilesL(TInt, const TDesC &, RFs &)

IMPORT_C TIntSaveBinaryValuesToFilesL(TIntaSizeThreshold,
const TDesC &aPath,
RFs &aFileSession
)

Saves all binary property values larger than a specified threshold to files, and sets each property value to be a URI representing the file rather than the binary data iself.

The files are created in the folder identified by aPath, and are assigned unique filenames that consist of the property name and some random numbers.

Each new URI property value is prefixed with file:// and contains the path and filename of the file created.

If a vCard contains any agent property values and if they contain binary data whose size exceeds the threshold, these property values are replaced with URI property values.

The function uses the file server session supplied, which is needed to create the files. It leaves if there is a problem creating any of the files.

Parameters

TInt aSizeThresholdThe threshold number of bytes for the binary data, above which the binary data is stored in a file.
const TDesC & aPathThe path identifying the location in which the files are created. This must not be greater than 240 characters long or the function leaves with KErrArgument. If it doesn't end in a slash, then one is appended.
RFs & aFileSessionThe file server session used to create the files.

SetAutoDetect(TBool, const CArrayFix< CCnvCharacterSetConverter::SCharacterSet > *)

IMPORT_C voidSetAutoDetect(TBoolaOn,
const CArrayFix< CCnvCharacterSetConverter::SCharacterSet > *aAutoDetectCharSets = NULL
)

Turns auto detection of character sets on or off.

If a property does not specify a character set, then it is possible to guess its character set. This function turns this behaviour on or off. When the behaviour is on, it also lets the caller specify a restricted set of character sets to be considered.

Auto-detection of character sets is used (if auto detection is on) when converting a property value to Unicode while internalising a stream.

Parameters

TBool aOnIf ETrue, auto detection is turned on; if EFalse (the default value), auto detection is turned off
const CArrayFix< CCnvCharacterSetConverter::SCharacterSet > * aAutoDetectCharSets = NULLIf specified then auto detection will only consider the character sets listed. If NULL, all available character sets are considered.

SetCharacterConverter(Versit::TEncodingAndCharset &)

IMPORT_C voidSetCharacterConverter(Versit::TEncodingAndCharset &encodingAndCharset)

Sets a character converter suitable for converting strings between Unicode and the specified character set.

The function finds a suitable converter for the character set specified in aEncodingAndCharset.iCharSetId, if one is available, and assigns it to aEncodingAndCharset.iConverter.

If there is no converter available for the specified character set then iConverter is set to NULL.

This function is only of use if executing a major change to the externalisation behaviour, particularly if overriding CParserProperty::ExternalizeL() - the function from which this function is called.

Parameters

Versit::TEncodingAndCharset & encodingAndCharsetA utility class from which the character set information is extracted (from its member iCharSetId) and to which the suitable character converter is set (to its member iConverter).

SetDefaultCharSet(const Versit::TVersitCharSet)

IMPORT_C voidSetDefaultCharSet(const Versit::TVersitCharSetaCharSet)

Sets the default character set or transformation format.

This may be used to represent property values in Versit objects.

Parameters

const Versit::TVersitCharSet aCharSetThe default character set.

SetDefaultCharSetId(TUint)

IMPORT_C voidSetDefaultCharSetId(TUintaCharSetId)

Sets the default character set or transformation format.

This may be used to represent property values in Versit objects.

Parameters

TUint aCharSetIdThe UID for the character set. These are defined in charconv.h.

SetDefaultEncoding(const Versit::TVersitEncoding)

IMPORT_C voidSetDefaultEncoding(const Versit::TVersitEncodingaEncoding)

Sets the parser's default encoding to aEncoding.

panic
Versit-Parser 7 aEncoding is Versit::EEightBitEncoding.

Parameters

const Versit::TVersitEncoding aEncodingAn encoding. Cannot be 8-bit.

SetEntityNameL(const TDesC &)

IMPORT_C voidSetEntityNameL(const TDesC &aEntityName)

Sets the name for the current entity to one of: VCARD, VCALENDAR, VEVENT or VTODO.

leave
KErrNoMemory Memory is allocated for the new entity name on the heap, so it can leave if there is insufficient memory available.

Parameters

const TDesC & aEntityNameThe new name for the current parser entity. Any existing name is first deleted.

MVersitObserver * aObserverA pointer to the observer.

SetPlugIn(MVersitPlugIn *)

voidSetPlugIn(MVersitPlugIn *aPlugIn)[inline]

Sets the Versit plug-in.

If there is one, the Versit plug-in needs to be set before any properties are added to the parser. This is done for you when internalising (using InternalizeL()) or adding properties (using AddPropertyL()).

Parameters

MVersitPlugIn * aPlugInA pointer to the plug in.
