Detailed Description
An implementation of
ID3v2 headers.
This class implements ID3v2 headers. It attempts to follow, both semantically and programatically, the structure specified in the ID3v2 standard. The API is based on the properties of ID3v2 headers specified there. If any of the terms used in this documentation are unclear please check the specification in the linked section. (Structure, 3.1)
Constructor & Destructor Documentation
TagLib::ID3v2::Header::Header |
( |
|
) |
|
|
|
Constructs an empty ID3v2 header. |
TagLib::ID3v2::Header::Header |
( |
const ByteVector & |
data |
) |
|
|
|
Constructs an ID3v2 header based on data. parse() is called immediately. |
virtual TagLib::ID3v2::Header::~Header |
( |
|
) |
[virtual] |

Member Function Documentation
uint TagLib::ID3v2::Header::completeTagSize |
( |
|
) |
const |
|
|
Returns the tag size, including the header and, if present, the footer size.
- See also:
- tagSize()
|
bool TagLib::ID3v2::Header::experimentalIndicator |
( |
|
) |
const |
|
|
Returns true if the experimental indicator flag is set. |
bool TagLib::ID3v2::Header::extendedHeader |
( |
|
) |
const |
|
|
Returns true if an extended header is present in the tag. |
ByteVector TagLib::ID3v2::Header::fileIdentifier |
( |
|
) |
[static] |
|
|
Returns the string used to identify and ID3v2 tag inside of a file. Presently this is always "ID3". |
bool TagLib::ID3v2::Header::footerPresent |
( |
|
) |
const |
|
|
Returns true if a footer is present in the tag. |
uint TagLib::ID3v2::Header::majorVersion |
( |
|
) |
const |
|
|
Returns the major version number. (Note: This is the 4, not the 2 in ID3v2.4.0. The 2 is implied.) |
void TagLib::ID3v2::Header::parse |
( |
const ByteVector & |
data |
) |
[protected] |
|
|
Called by setData() to parse the header data. It makes this information available through the public API. |
ByteVector TagLib::ID3v2::Header::render |
( |
|
) |
const |
|
|
Renders the Header back to binary format. |
uint TagLib::ID3v2::Header::revisionNumber |
( |
|
) |
const |
|
|
Returns the revision number. (Note: This is the 0, not the 4 in ID3v2.4.0. The 2 is implied.) |
void TagLib::ID3v2::Header::setData |
( |
const ByteVector & |
data |
) |
|
|
|
Sets the data that will be used as the extended header. 10 bytes, starting from data will be used. |
void TagLib::ID3v2::Header::setTagSize |
( |
uint |
s |
) |
|
|
uint TagLib::ID3v2::Header::size |
( |
|
) |
[static] |
|
|
Returns the size of the header. Presently this is always 10 bytes. |
uint TagLib::ID3v2::Header::tagSize |
( |
|
) |
const |
|
|
Returns the tag size in bytes. This is the size of the frame content. The size of the entire tag will be this plus the header size (10 bytes) and, if present, the footer size (potentially another 10 bytes).
- Note:
- This is the value as read from the header to which TagLib attempts to provide an API to; it was not a design decision on the part of TagLib to not include the mentioned portions of the tag in the size.
- See also:
- completeTagSize()
|
bool TagLib::ID3v2::Header::unsynchronisation |
( |
|
) |
const |
|
|
Returns true if unsynchronisation has been applied to all frames. |
