AttachmentsSizeL(CMsvStore &)

IMPORT_C TInt

AttachmentsSizeL

(

CMsvStore &

aStore

)

[static]

Returns total size of all attachments including mime headers and binary attachment data. Linked attachments are included This function is needed to allocate the encoding buffer.

Parameters

CMsvStore & aStore

Read store for the message entry

Constructor.

CreateAttachmentL(CMsvStore &, RFile &, RFs &, TDriveUnit, TDesC8 &, CMsvMimeHeaders &, CMsvAttachment *, TMsvAttachmentId &)

IMPORT_C void	CreateAttachmentL	(	CMsvStore &	aStore,
			RFile &	aFile,
			RFs &	aFs,
			TDriveUnit	aMessageDrive,
			TDesC8 &	aMimeType,
			CMsvMimeHeaders &	aMimeHeaders,
			CMsvAttachment *	aAttachmentInfo,
			TMsvAttachmentId &	aAttaId
		)	[static]

Create attachment entry and copy specified file to binary file storage.

Parameters

CMsvStore & aStore	an open EditStore. Caller must commit store (several attachments can be added before committing store)
RFile & aFile	opened file handle, source of the attachment. File must be in public location to be accessible. Caller must close the file afterwards.
RFs & aFs	File session handle. Needed to check disk space
TDriveUnit aMessageDrive	the drive the message store is on. (needed for disk space check)
TDesC8 & aMimeType	mime type of the attachmet.
CMsvMimeHeaders & aMimeHeaders	mime headers for the attachment. If content type is not defined, function adds the mime type and subtype from aMimeType Suggested filename in mimeHeaders is used as attachment name
CMsvAttachment * aAttachmentInfo	must be initialized to a CMsvAttachment::EMsvFile on return contains data about the attachment. Ownership of attachmentinfo is transferred to attachment manager, it must not be deleted by caller. Attachment manager will be destroyed when store is deleted. After that aAttachmentInfo will no longer be available.
TMsvAttachmentId & aAttaId	attachment id of the newly created attachment

CreateTextAttachmentL(CMsvStore &, TMsvAttachmentId &, const TDesC &, const TDesC &, RFs &, TDriveUnit, TBool)

IMPORT_C void	CreateTextAttachmentL	(	CMsvStore &	aStore,
			TMsvAttachmentId &	aAttachmentId,
			const TDesC &	aText,
			const TDesC &	aFile,
			RFs &	aFs,
			TDriveUnit	aMessageDrive,
			TBool	aConvertParagraphSeparator = ETrue
		)	[static]

Create text/plain attachment. Creates a text attachment from descriptor. Has option to convert all unicode paragraph separator marks to line feeds. Converts text from unicode (ucs-2) to utf-8 before storing it.

Parameters

CMsvStore & aStore	an open EditStore. Caller must commit store (several attachments can be added before committing store)
TMsvAttachmentId & aAttachmentId	returned ID of the new attachment entry
const TDesC & aText	UNICODE text to be added as a text/plain attachment.
const TDesC & aFile	suggested filename for the attachment
RFs & aFs	File session handle. Needed to check disk space
TDriveUnit aMessageDrive	the drive the message store is on. (needed for disk space check)
TBool aConvertParagraphSeparator = ETrue	flag to tell if the function will search for all 0x2029 characters (Unicode paragraph separator) and replace them with 0x000a (line feed). aConvertParagraphSeparator == ETrue: convert aConvertParagraphSeparator == EFalse: do not convert

CreateUTF8TextAttachmentFromFileL(CMsvStore &, TMsvAttachmentId &, RFile &, RFs &, TDriveUnit)

IMPORT_C void	CreateUTF8TextAttachmentFromFileL	(	CMsvStore &	aStore,
			TMsvAttachmentId &	aAttachmentId,
			RFile &	aFile,
			RFs &	aFs,
			TDriveUnit	aMessageDrive
		)	[static]

Parameters

CMsvStore & aStore	an open EditStore. Caller must commit store (several attachments can be added before committing store)
TMsvAttachmentId & aAttachmentId	returned ID of the new attachment entry
RFile & aFile	open file read handle to unicode plain text file
RFs & aFs	File session handle. Needed to check disk space
TDriveUnit aMessageDrive	the drive the message store is on. (needed for disk space check)

IsValidFilename(RFs &, const TPtrC &)

IMPORT_C TBool	IsValidFilename	(	RFs &	aFs,
			const TPtrC &	aFileName
		)	[static]

Check if aFileName would be a valid filename. Cannot use path because absolute path is not known. Only filename is checked

Parameters

RFs & aFs	open file system handle.
const TPtrC & aFileName	suggestion of a filename.

NewL()

IMPORT_C CMmsAttachmentHandler *

NewL

(

)

[static]

Two-phased constructor.

RemoveAttachmentL(TMsvAttachmentId, CMsvStore &)

void	RemoveAttachmentL	(	TMsvAttachmentId	aAttaId,
			CMsvStore &	aStore
		)	[private, static]

Remove an attachment by attaId. Symbian synchronous attachment manager can only remove by index.

Parameters

TMsvAttachmentId aAttaId	id of the attachment to be removed
CMsvStore & aStore	reference to open edit store
