Detailed Description

An implementation of TagLib::File with TrueAudio specific methods.

This implements and provides an interface for TrueAudio files to the TagLib::Tag and TagLib::AudioProperties interfaces by way of implementing the abstract TagLib::File API as well as providing some additional information specific to TrueAudio files.

Constructor & Destructor Documentation

◆ File() [1/5]

TagLib::TrueAudio::File::File ( FileName file,
bool readProperties = true,
Properties::ReadStyle propertiesStyle = Properties::Average,
ID3v2::FrameFactory * frameFactory = nullptr )

Constructs a TrueAudio file from file. If readProperties is true the file's audio properties will also be read.

If this file contains an ID3v2 tag, the frames will be created using frameFactory (default if null).

Note
In the current implementation, propertiesStyle is ignored.

References TagLib::AudioProperties::Average, and TAGLIB_DEPRECATED.

Referenced by File(), and operator=().

◆ File() [2/5]

TAGLIB_DEPRECATED TagLib::TrueAudio::File::File ( FileName file,
ID3v2::FrameFactory * frameFactory,
bool readProperties = true,
Properties::ReadStyle propertiesStyle = Properties::Average )

Constructs a TrueAudio file from file. If readProperties is true the file's audio properties will also be read.

If this file contains an ID3v2 tag, the frames will be created using frameFactory.

Note
In the current implementation, propertiesStyle is ignored.
Deprecated
Use the constructor above.

References TagLib::AudioProperties::Average.

◆ File() [3/5]

TagLib::TrueAudio::File::File ( IOStream * stream,
bool readProperties = true,
Properties::ReadStyle propertiesStyle = Properties::Average,
ID3v2::FrameFactory * frameFactory = nullptr )

Constructs a TrueAudio file from stream. If readProperties is true the file's audio properties will also be read.

Note
TagLib will not take ownership of the stream, the caller is responsible for deleting it after the File object.

If this file contains an ID3v2 tag, the frames will be created using frameFactory.

Note
In the current implementation, propertiesStyle is ignored.

References TagLib::AudioProperties::Average, and TAGLIB_DEPRECATED.

◆ File() [4/5]

TAGLIB_DEPRECATED TagLib::TrueAudio::File::File ( IOStream * stream,
ID3v2::FrameFactory * frameFactory,
bool readProperties = true,
Properties::ReadStyle propertiesStyle = Properties::Average )

Constructs a TrueAudio file from stream. If readProperties is true the file's audio properties will also be read.

Note
TagLib will not take ownership of the stream, the caller is responsible for deleting it after the File object.

If this file contains an ID3v2 tag, the frames will be created using frameFactory.

Note
In the current implementation, propertiesStyle is ignored.
Deprecated
Use the constructor above.

◆ ~File()

TagLib::TrueAudio::File::~File ( )
overridevirtual

Destroys this instance of the File.

Reimplemented from TagLib::File.

◆ File() [5/5]

TagLib::TrueAudio::File::File ( const File & )
delete

Member Function Documentation

◆ audioProperties()

Properties * TagLib::TrueAudio::File::audioProperties ( ) const
overridevirtual

Returns the TrueAudio::Properties for this file. If no audio properties were read then this will return a null pointer.

Implements TagLib::File.

◆ hasID3v1Tag()

bool TagLib::TrueAudio::File::hasID3v1Tag ( ) const

Returns whether or not the file on disk actually has an ID3v1 tag.

See also
ID3v1Tag()

◆ hasID3v2Tag()

bool TagLib::TrueAudio::File::hasID3v2Tag ( ) const

Returns whether or not the file on disk actually has an ID3v2 tag.

See also
ID3v2Tag()

◆ ID3v1Tag()

ID3v1::Tag * TagLib::TrueAudio::File::ID3v1Tag ( bool create = false)

Returns a pointer to the ID3v1 tag of the file.

If create is false (the default) this may return a null pointer if there is no valid ID3v1 tag. If create is true it will create an ID3v1 tag if one does not exist and returns a valid pointer.

Note
This may return a valid pointer regardless of whether or not the file on disk has an ID3v1 tag. Use hasID3v1Tag() to check if the file on disk actually has an ID3v1 tag.
The Tag is still owned by the TrueAudio::File and should not be deleted by the user. It will be deleted when the file (object) is destroyed.
See also
hasID3v1Tag()

◆ ID3v2Tag()

ID3v2::Tag * TagLib::TrueAudio::File::ID3v2Tag ( bool create = false)

Returns a pointer to the ID3v2 tag of the file.

If create is false (the default) this may return a null pointer if there is no valid ID3v2 tag. If create is true it will create an ID3v2 tag if one does not exist and returns a valid pointer.

Note
This may return a valid pointer regardless of whether or not the file on disk has an ID3v2 tag. Use hasID3v2Tag() to check if the file on disk actually has an ID3v2 tag.
The Tag is still owned by the TrueAudio::File and should not be deleted by the user. It will be deleted when the file (object) is destroyed.
See also
hasID3v2Tag()

◆ isSupported()

bool TagLib::TrueAudio::File::isSupported ( IOStream * stream)
static

Returns whether or not the given stream can be opened as a TrueAudio file.

Note
This method is designed to do a quick check. The result may not necessarily be correct.

References TAGLIB_MSVC_SUPPRESS_WARNING_NEEDS_TO_HAVE_DLL_INTERFACE.

◆ operator=()

File & TagLib::TrueAudio::File::operator= ( const File & )
delete

References File().

◆ properties()

PropertyMap TagLib::TrueAudio::File::properties ( ) const
overridevirtual

Implements the unified property interface – export function. If the file contains both ID3v1 and v2 tags, only ID3v2 will be converted to the PropertyMap.

Reimplemented from TagLib::File.

◆ removeUnsupportedProperties()

void TagLib::TrueAudio::File::removeUnsupportedProperties ( const StringList & properties)
overridevirtual

Removes unsupported properties, or a subset of them, from the file's metadata. The parameter properties must contain only entries from properties().unsupportedData().

Reimplemented from TagLib::File.

◆ save()

bool TagLib::TrueAudio::File::save ( )
overridevirtual

Saves the file.

Implements TagLib::File.

◆ setProperties()

PropertyMap TagLib::TrueAudio::File::setProperties ( const PropertyMap & )
overridevirtual

Implements the unified property interface – import function. Creates in ID3v2 tag if necessary. If an ID3v1 tag exists, it will be updated as well, within the limitations of ID3v1.

Reimplemented from TagLib::File.

◆ strip()

void TagLib::TrueAudio::File::strip ( int tags = AllTags)

This will remove the tags that match the OR-ed together TagTypes from the file. By default it removes all tags.

Note
This will also invalidate pointers to the tags as their memory will be freed.
In order to make the removal permanent save() still needs to be called

References AllTags.

◆ tag()

TagLib::Tag * TagLib::TrueAudio::File::tag ( ) const
overridevirtual

Returns the Tag for this file.

Implements TagLib::File.
