40 | /** Class for converting the core Ogre data types to/from Strings. |
---|
41 | @remarks |
---|
42 | The code for converting values to and from strings is here as a separate |
---|
43 | class to avoid coupling String to other datatypes (and vice-versa) which reduces |
---|
44 | compilation dependency: important given how often the core types are used. |
---|
45 | @par |
---|
46 | This class is mainly used for parsing settings in text files. External applications |
---|
47 | can also use it to interface with classes which use the StringInterface template |
---|
48 | class. |
---|
49 | @par |
---|
50 | The String formats of each of the major types is listed with the methods. The basic types |
---|
51 | like int and Real just use the underlying C runtime library atof and atoi family methods, |
---|
52 | however custom types like Vector3, ColourValue and Matrix4 are also supported by this class |
---|
53 | using custom formats. |
