Detailed Description

A wrapper around QMimeDatabase that supports additional mime types.

QMimeDatabase by default uses a list of MIME types provided by Freedesktop.org. Unfortunately it does not include a few MIME types (most notably the Apple plist types) and we cannot inherit from either QMimeDatabase or QMimeType to add new types. Qt does have a mechanism for adding additional types by extending the search path it uses. So for example, on unix systems, we could add our custom types to /usr/local/share/mythtv/mime/packages and add that path to XDG_DATA_DIRS (and this does work). It is not clear however how this would work on other platforms. On Android, for example, the 'GenericDataLocation' in QStandardPaths defaults to the USER directory.

Member Function Documentation

AllTypes()

MythMimeTypes MythMimeDatabase::AllTypes ( )

static

Return a vector containing all of the known types (both Qt and MythTV)

Definition at line 165 of file mythmimedatabase.cpp.

MimeTypeForName()

MythMimeType MythMimeDatabase::MimeTypeForName ( const QString &  Name )

static

Return a mime type that matches the given name.

Note

We prioritise internal types over Qt types as our internal types are either non-ambiguous (e.g. cbor) or are generated internally (and we thus know their type).

If a suitable mime type is not found, an invalid type is returned.

SuffixForFileName()

QString MythMimeDatabase::SuffixForFileName ( const QString &  FileName )

static

Return the preferred suffix for the given filename.

Note

The suffix does not include any 'dots' and is always lower case.

Definition at line 187 of file mythmimedatabase.cpp.

Referenced by MythHTTPEncoding::GetMimeType().

MimeTypesForFileName()

MythMimeTypes MythMimeDatabase::MimeTypesForFileName ( const QString &  FileName )

static

Return a vector of mime types that match the given filename.

Definition at line 175 of file mythmimedatabase.cpp.

Referenced by MythHTTPEncoding::GetMimeType().

MimeTypeForFileNameAndData() [1/2]

MythMimeType MythMimeDatabase::MimeTypeForFileNameAndData ( const QString &  FileName, const QByteArray &  Data  )

static

Return a mime type for the given FileName and data.

As for QMimeDatabase, this method will default to using the file name where it is unambiguous and only probe the given data when further help is needed.

MythTV types are probed first.

Note

A valid mimetype is always returned (the default being 'application/octet-stream')
