---|
| 52 | @remarks |
---|
| 53 | The code for converting values to and from strings is here as a separate |
---|
| 54 | class to avoid coupling String to other datatypes (and vice-versa) which reduces |
---|
| 55 | compilation dependency: important given how often the core types are used. |
---|
| 56 | @par |
---|
| 57 | This class is mainly used for parsing settings in text files. External applications |
---|
| 58 | can also use it to interface with classes which use the StringInterface template |
---|
| 59 | class. |
---|
| 60 | @par |
---|
| 61 | The String formats of each of the major types is listed with the methods. The basic types |
---|
| 62 | like int and Real just use the underlying C runtime library atof and atoi family methods, |
---|
| 63 | however custom types like Vector3, ColourValue and Matrix4 are also supported by this class |
---|
| 64 | using custom formats. |
