Overview

A wide string class suitable for unicode. .

This is an implicitly shared wide string. For storage it uses TagLib::wstring, but as this is an implementation detail this of course could change. Strings are stored internally as UTF-16BE. (Without the BOM (Byte Order Mark)The use of implicit sharing means that copying a string is cheap, the only cost comes into play when the copy is modified. Prior to that the string just has a pointer to the data of the parent String. This also makes this class suitable as a function return type.In addition to adding implicit sharing, this class keeps track of four possible encodings, which are the four supported by the ID3v2 standard.

Instance Method Details

#toCString(unicode = false) ⇒ Object

Creates and returns a C-String based on the data. This string is still owned by the String (class) and as such should not be deleted by the user.If unicode if false (the default) this string will be encoded in Latin1. If it is true the returned C-String will be UTF-8 encoded.This string remains valid until the String instance is destroyed or another export method is called.This however has the side effect that this C-String will remain in memory in addition to other memory that is consumed by the String instance. So, this method should not be used on large strings or where memory is critical.
