Detailed Description

Convenience class for encapsulating Vorbis comment entries. An entry is a vendor string or a comment field. In the case of a vendor string, the field name is undefined; only the field value is relevant.

A field as used in the methods refers to an entire 'NAME=VALUE' string; for convenience the string is NUL-terminated. A length field is required in the unlikely event that the value contains contain embedded NULs.

A field_name is what is on the left side of the first '=' in the field. By definition it is ASCII and so is NUL-terminated and does not require a length to describe it. field_name is undefined for a vendor string entry.

A field_value is what is on the right side of the first '=' in the field. By definition, this may contain embedded NULs and so a field_value_length is required to describe it. However in practice, embedded NULs are not known to be used, so it is generally safe to treat field values as NUL- terminated UTF-8 strings.

Always check is_valid() after the constructor or operator= to make sure memory was properly allocated and that the Entry conforms to the Vorbis comment specification.
