Detailed Description

Fetches mailbox metadata.

Provides support for the IMAP METADATA extension; both the final RFC version (RFC 5464) and the older, incompatible draft version (known as ANNOTATEMORE) (draft-daboo-imap-annotatemore-07). See setServerCompatibility().

This job can only be run when the session is in the authenticated (or selected) state.

If the server supports ACLs, the user will need the Acl::Lookup right on the mailbox, as well as one of

• Acl::Read
• Acl::KeepSeen
• Acl::Write
• Acl::Insert
• Acl::Post Otherwise, the user must be able to list the mailbox and either read or write the message content.

Note also that on servers that implement the Annotatemore version of the extension, only Acl::Lookup rights are required (ie: the user must be able to list the mailbox).

Member Function Documentation

addEntry()

void GetMetaDataJob::addEntry	(	const QByteArray &	entry,
		const QByteArray &	attribute = QByteArray() )

Add an entry to the query list.

See SetMetaDataJob for a description of metadata entry names.

When operating in Annotatemore mode, you should provide an attribute name. Typically this will be "value", "value.priv" or "value.shared", although you might want to fetch the "content-type" or "content-language" attributes as well.

Parameters

entry	the metadata entry name
attribute	the attribute name, in Annotatemore mode

Deprecated

use addRequestedEntry(QByteArray) instead

Definition at line 170 of file getmetadatajob.cpp.

addRequestedEntry()

void GetMetaDataJob::addRequestedEntry

(

const QByteArray &

entry

)

Add an entry to the query list.

See SetMetaDataJob for a description of metadata entry names.

Note that this expects METADATA style entries (with a /shared or /private prefix typically). In ANNOTATEMORE mode, this prefix is automatically replaced with an appropriate attribute.

Parameters

entry

the metadata entry name

Definition at line 180 of file getmetadatajob.cpp.

allMetaData() [1/2]

QMap< QByteArray, QByteArray > GetMetaDataJob::allMetaData

(

)

const

Get all the metadata for the mailbox set with setMailBox().

Note that the returned map uses METADATA style entries (with a /shared or /private prefix typically), also in ANNOTATEMORE mode.

Returns

a map from metadata entry names to values

Definition at line 240 of file getmetadatajob.cpp.

allMetaData() [2/2]

QMap< QByteArray, QMap< QByteArray, QByteArray > > GetMetaDataJob::allMetaData

(

const QString &

mailBox

)

const

Get all the metadata for a given mailbox.

The returned map is from metadata entry names to attributes or values.

If operating in Metadata mode, the metadata value is stored against the empty QByteArray:

map = job.allMetaData( "INBOX" );
QByteArray value = map[ "/shared/comment" ].value( QByteArray() );

The equivalent in Annotatemore mode would be:

map = job.allMetaData( "INBOX" );
QByteArray value = map[ "/comment" ].value( "value.shared" );

Parameters

mailBox

a mailbox name or an empty string for server metadata

Returns

a map from metadata entry names to attributes or values

Definition at line 234 of file getmetadatajob.cpp.

allMetaDataForMailbox()

QMap< QByteArray, QByteArray > GetMetaDataJob::allMetaDataForMailbox

(

const QString &

mailbox

)

const

Get all the metadata for the mailbox.

Note that the returned map uses METADATA style entries (with a /shared or /private prefix typically), also in ANNOTATEMORE mode.

Returns

a map from metadata entry names to values

Definition at line 246 of file getmetadatajob.cpp.

allMetaDataForMailboxes()

QHash< QString, QMap< QByteArray, QByteArray > > GetMetaDataJob::allMetaDataForMailboxes

(

)

const

Get all the metadata for for all mailboxes.

Note that the returned map uses METADATA style entries (with a /shared or /private prefix typically), also in ANNOTATEMORE mode.

Returns

a map in the form (mailbox, (entry, value))

Definition at line 260 of file getmetadatajob.cpp.

doStart()

void GetMetaDataJob::doStart ( )

overrideprotected

Definition at line 64 of file getmetadatajob.cpp.

handleResponse()

void GetMetaDataJob::handleResponse ( const Message & response )

overrideprotected

Definition at line 129 of file getmetadatajob.cpp.

metaData() [1/2]

QByteArray GetMetaDataJob::metaData

(

const QByteArray &

entry

)

const

Get a single metadata entry.

The metadata must have been requested using addEntry(), and the job must have completed successfully, or this method will not return anything.

Note that if setMaximumSize() was used to limit the size of returned metadata, this method may return an empty QByteArray even if the metadata entry was requested and exists on the server. This will happen when the metadata entry is larger than the size limit given to setMaximumSize().

Note that this expects METADATA style entries (with a /shared or /private prefix typically). In ANNOTATEMORE mode, this prefix is automatically replaced with an appropriate attribute.

Parameters

entry

the entry to get

Returns

the metadata entry value

Definition at line 227 of file getmetadatajob.cpp.

metaData() [2/2]

QByteArray GetMetaDataJob::metaData	(	const QString &	mailBox,
		const QByteArray &	entry,
		const QByteArray &	attribute = QByteArray() ) const

Get a single metadata entry.

The metadata must have been requested using addEntry(), and the job must have completed successfully, or this method will not return anything.

Note that if setMaximumSize() was used to limit the size of returned metadata, this method may return an empty QByteArray even if the metadata entry was requested and exists on the server. This will happen when the metadata entry is larger than the size limit given to setMaximumSize().

Parameters

mailBox	the mailbox the metadata is attached to, or an empty string for server metadata
entry	the entry to get
attribute	(only in Annotatemore mode) the attribute to get

Returns

the metadata entry value

Deprecated

use metaData(QByteArray entry) instead

Definition at line 209 of file getmetadatajob.cpp.

setDepth()

void GetMetaDataJob::setDepth

(

Depth

depth

)

Sets whether to retrieve children or descendants of the requested entries.

Metadata entry names are heirachical, much like UNIX path names. It therefore makes sense to ask for an entry and all its children (OneLevel) or an entry and all its descendants (AllLevels).

For example, /shared/foo/bar/baz is a child of /shared/foo/bar and a descendent of /shared/foo. So if you request the entry "/shared/foo" with depth NoDepth, you will only get the "/shared/foo" entry. If you set the depth to OneLevel, you will also get "/shared/foo/bar". If you set the depth to AllLevels, you will also get "/shared/foo/bar/baz", and every other metadata entry that starts with "/shared/foo/".

Note that this is only used when the server capability mode is Metadata.

Parameters

depth

the depth of the metadata tree to return

Definition at line 193 of file getmetadatajob.cpp.

setMaximumSize()

void GetMetaDataJob::setMaximumSize

(

qint64

size

)

Limits the size of returned metadata entries.

In order to save time or bandwidth, it is possible to prevent the server from returning metadata entries that are larger than a certain size. These entries will simply not appear in the list returned by allMetaData(), and will not be accessible using metaData().

Note that this is only used when the server capability mode is Metadata.

The default is no limit (-1). A value of less than -1 will cause the job to fail.

Parameters

size	the entry size limit, in octets, or -1 for no limit
