This is an implementation of ID3v2 chapter frames.
The purpose of this frame is to describe a single chapter within an audio file.An implementation of ID3v2 chapter frames
TagLib::ID3v2::ChapterFrame::ChapterFrame | ( | const ID3v2::Header * | tagHeader, |
const ByteVector & | data | ||
) |
Creates a chapter frame based on data.
tagHeader is required as the internal frames are parsed based on the tag version.
TagLib::ID3v2::ChapterFrame::ChapterFrame | ( | const ByteVector & | elementID, |
unsigned int | startTime, | ||
unsigned int | endTime, | ||
unsigned int | startOffset, | ||
unsigned int | endOffset, | ||
const FrameList & | embeddedFrames = FrameList() |
||
) |
Creates a chapter frame with the element ID elementID, start time startTime, end time endTime, start offset startOffset, end offset endOffset and optionally a list of embedded frames, whose ownership will then be taken over by this Frame, in embeededFrames;.
All times are in milliseconds.
|
virtual |
Destroys the frame.
void TagLib::ID3v2::ChapterFrame::addEmbeddedFrame | ( | Frame * | frame | ) |
Add an embedded frame to the CHAP frame.
At this point the CHAP frame takes ownership of the embedded frame and will handle freeing its memory.
PropertyMap TagLib::ID3v2::ChapterFrame::asProperties | ( | ) | const |
ByteVector TagLib::ID3v2::ChapterFrame::elementID | ( | ) | const |
Returns the element ID of the frame.
Element ID is a null terminated string, however it's not human-readable.
const FrameList& TagLib::ID3v2::ChapterFrame::embeddedFrameList | ( | ) | const |
Returns a reference to the embedded frame list.
This is an FrameList of all of the frames embedded in the CHAP frame in the order that they were parsed.
This can be useful if for example you want iterate over the CHAP frame's embedded frames in the order that they occur in the CHAP frame.
const FrameList& TagLib::ID3v2::ChapterFrame::embeddedFrameList | ( | const ByteVector & | frameID | ) | const |
Returns the embedded frame list for frames with the id frameID or an empty list if there are no embedded frames of that type.
This is just a convenience and is equivalent to:
const FrameListMap& TagLib::ID3v2::ChapterFrame::embeddedFrameListMap | ( | ) | const |
Returns a reference to the frame list map.
This is an FrameListMap of all of the frames embedded in the CHAP frame.
This is the most convenient structure for accessing the CHAP frame's embedded frames. Many frame types allow multiple instances of the same frame type so this is a map of lists. In most cases however there will only be a single frame of a certain type.
unsigned int TagLib::ID3v2::ChapterFrame::endOffset | ( | ) | const |
Returns zero based byte offset (count of bytes from the beginning of the audio file) of chapter's end.
unsigned int TagLib::ID3v2::ChapterFrame::endTime | ( | ) | const |
Returns time of chapter's end (in milliseconds).
|
static |
CHAP frames each have a unique element ID.
This searches for a CHAP frame with the element ID eID and returns a pointer to it. This can be used to link CTOC and CHAP frames together.
|
protectedvirtual |
Called by parse() to parse the field data.
It makes this information available through the public API. This must be overridden by the subclasses.
Implements TagLib::ID3v2::Frame.
void TagLib::ID3v2::ChapterFrame::removeEmbeddedFrame | ( | Frame * | frame, |
bool | del = true |
||
) |
Remove an embedded frame from the CHAP frame.
If del is true the frame's memory will be freed; if it is false, it must be deleted by the user.
void TagLib::ID3v2::ChapterFrame::removeEmbeddedFrames | ( | const ByteVector & | id | ) |
Remove all embedded frames of type id from the CHAP frame and free their memory.
|
protectedvirtual |
Render the field data back to a binary format in a ByteVector.
This must be overridden by subclasses.
Implements TagLib::ID3v2::Frame.
void TagLib::ID3v2::ChapterFrame::setElementID | ( | const ByteVector & | eID | ) |
Sets the element ID of the frame to eID.
If eID isn't null terminated, a null char is appended automatically.
void TagLib::ID3v2::ChapterFrame::setEndOffset | ( | const unsigned int & | eO | ) |
Sets zero based byte offset (count of bytes from the beginning of the audio file) of chapter's end to eO.
void TagLib::ID3v2::ChapterFrame::setEndTime | ( | const unsigned int & | eT | ) |
Sets time of chapter's end (in milliseconds) to eT.
void TagLib::ID3v2::ChapterFrame::setStartOffset | ( | const unsigned int & | sO | ) |
Sets zero based byte offset (count of bytes from the beginning of the audio file) of chapter's start to sO.
void TagLib::ID3v2::ChapterFrame::setStartTime | ( | const unsigned int & | sT | ) |
Sets time of chapter's start (in milliseconds) to sT.
unsigned int TagLib::ID3v2::ChapterFrame::startOffset | ( | ) | const |
Returns zero based byte offset (count of bytes from the beginning of the audio file) of chapter's start.
unsigned int TagLib::ID3v2::ChapterFrame::startTime | ( | ) | const |
Returns time of chapter's start (in milliseconds).
|
virtual |
This returns the textual representation of the data in the frame.
Subclasses must reimplement this method to provide a string representation of the frame's data.
