Detailed Description

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

This implements and provides an interface for DSDIFF 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 DSDIFF files.

Member Enumeration Documentation

◆ Endianness

Enumerator
BigEndian 
LittleEndian 

◆ TagTypes

This set of flags is used for various operations and is suitable for being OR-ed together.

Enumerator
NoTags 

Empty set. Matches no tag types.

DIIN 

Matches DIIN tags.

ID3v2 

Matches ID3v2 tags.

AllTags 

Matches all tag types.

Constructor & Destructor Documentation

◆ File() [1/2]

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

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

Note
In the current implementation, propertiesStyle is ignored.

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

◆ File() [2/2]

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

Constructs a DSDIFF file from stream. 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
TagLib will not take ownership of the stream, the caller is responsible for deleting it after the File object.
In the current implementation, propertiesStyle is ignored.

◆ ~File()

TagLib::DSDIFF::File::~File ( )
overridevirtual

Destroys this instance of the File.

Reimplemented from TagLib::File.

Member Function Documentation

◆ audioProperties()

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

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

Implements TagLib::File.

◆ DIINTag()

DSDIFF::DIIN::Tag * TagLib::DSDIFF::File::DIINTag ( bool  create = false) const

Returns the DSDIFF DIIN Tag for this file

◆ hasDIINTag()

bool TagLib::DSDIFF::File::hasDIINTag ( ) const

Returns whether or not the file on disk actually has the DSDIFF title and artist tags.

See also
DIINTag()

◆ hasID3v2Tag()

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

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

See also
ID3v2Tag()

◆ ID3v2Tag()

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

Returns the ID3V2 Tag for this file.

Note
This always returns 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.
See also
hasID3v2Tag()

◆ isSupported()

static bool TagLib::DSDIFF::File::isSupported ( IOStream stream)
static

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

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

◆ properties()

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

Implements the unified property interface – export function. This method forwards to ID3v2::Tag::properties().

Reimplemented from TagLib::File.

◆ removeUnsupportedProperties()

void TagLib::DSDIFF::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() [1/2]

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

Save the file. If at least one tag – ID3v1 or DIIN – exists this will duplicate its content into the other tag. This returns true if saving was successful.

If neither exists or if both tags are empty, this will strip the tags from the file.

This is the same as calling save(AllTags);

If you would like more granular control over the content of the tags, with the concession of generality, use parameterized save call below.

See also
save(int tags)

Implements TagLib::File.

◆ save() [2/2]

bool TagLib::DSDIFF::File::save ( int  tags,
StripTags  strip = StripOthers,
ID3v2::Version  version = ID3v2::v4 
)

Save the file. If strip is specified, it is possible to choose if tags not specified in tags should be stripped from the file or retained. With version, it is possible to specify whether ID3v2.4 or ID3v2.3 should be used.

◆ setProperties()

PropertyMap TagLib::DSDIFF::File::setProperties ( const PropertyMap )
overridevirtual

Implements the unified property interface – import function. This method forwards to ID3v2::Tag::setProperties().

Reimplemented from TagLib::File.

◆ strip()

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

This will strip the tags that match the OR-ed together TagTypes from the file. By default it strips all tags. It returns true if the tags are successfully stripped.

Note
This will update the file immediately.

◆ tag()

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

Returns a pointer to a tag that is the union of the ID3v2 and DIIN tags. The ID3v2 tag is given priority in reading the information – if requested information exists in both the ID3v2 tag and the ID3v1 tag, the information from the ID3v2 tag will be returned.

If you would like more granular control over the content of the tags, with the concession of generality, use the tag-type specific calls.

Note
As this tag is not implemented as an ID3v2 tag or a DIIN tag, but a union of the two this pointer may not be cast to the specific tag types.
