Detailed Description

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

This implements and provides an interface for MPC 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 MPC files. The only invalid tag combination supported is an ID3v1 tag after an APE tag.


Member Enumeration Documentation

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.

ID3v1 

Matches ID3v1 tags.

ID3v2 

Matches ID3v2 tags.

APE 

Matches APE tags.

AllTags 

Matches all tag types.


Constructor & Destructor Documentation

TagLib::MPC::File::File ( FileName  file,
bool  readProperties = true,
Properties::ReadStyle  propertiesStyle = Properties::Average 
)

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

Note:
In the current implementation, propertiesStyle is ignored.
TagLib::MPC::File::File ( IOStream stream,
bool  readProperties = true,
Properties::ReadStyle  propertiesStyle = Properties::Average 
)

Constructs an MPC 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.
In the current implementation, propertiesStyle is ignored.
virtual TagLib::MPC::File::~File ( ) [virtual]

Destroys this instance of the File.

Reimplemented from TagLib::File.


Member Function Documentation

APE::Tag* TagLib::MPC::File::APETag ( bool  create = false)

Returns a pointer to the APE tag of the file.

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

Note:
This may return a valid pointer regardless of whether or not the file on disk has an APE tag. Use hasAPETag() to check if the file on disk actually has an APE tag.
The Tag is still owned by the MPEG::File and should not be deleted by the user. It will be deleted when the file (object) is destroyed.
See also:
hasAPETag()
virtual Properties* TagLib::MPC::File::audioProperties ( ) const [virtual]

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

Implements TagLib::File.

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

See also:
APETag()

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

See also:
ID3v1Tag()
ID3v1::Tag* TagLib::MPC::File::ID3v1Tag ( bool  create = false)

Returns a pointer to the ID3v1 tag of the file.

If create is false (the default) this returns a null pointer if there is no valid APE tag. If create is true it will create an APE 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 MPEG::File and should not be deleted by the user. It will be deleted when the file (object) is destroyed.
See also:
hasID3v1Tag()

Implements the unified property interface -- export function. If the file contains both an APE and an ID3v1 tag, only the APE tag will be converted to the PropertyMap.

Reimplemented from TagLib::File.

void TagLib::MPC::File::remove ( int  tags = AllTags)
See also:
strip

Removes unsupported properties, or a subset of them, from the file's metadata. The parameter properties must contain only entries from properties().unsupportedData(). BIC: Will be mad virtual in future releases.

Reimplemented from TagLib::File.

virtual bool TagLib::MPC::File::save ( ) [virtual]

Saves the file.

This returns true if the save was successful.

Implements TagLib::File.

Implements the unified property interface -- import function. Affects only the APEv2 tag which will be created if necessary. If an ID3v1 tag exists, it will be updated as well.

Reimplemented from TagLib::File.

void TagLib::MPC::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.

Warning:
This will also invalidate pointers to the tags as their memory will be freed.
Note:
In order to make the removal permanent save() still needs to be called.
virtual TagLib::Tag* TagLib::MPC::File::tag ( ) const [virtual]

Returns the Tag for this file. This will be an APE tag, an ID3v1 tag or a combination of the two.

Implements TagLib::File.
