Detailed Description

Class for converting the core Ogre data types to/from Strings.

Remarks

The code for converting values to and from strings is here as a separate class to avoid coupling String to other datatypes (and vice-versa) which reduces compilation dependency: important given how often the core types are used.

This class is mainly used for parsing settings in text files. External applications can also use it to interface with classes which use the StringInterface template class.

The String formats of each of the major types is listed with the methods. The basic types like int and Real just use the underlying C runtime library atof and atoi family methods, however custom types like Vector3, ColourValue and Matrix4 are also supported by this class using custom formats.

isNumber()

static bool Ogre::StringConverter::isNumber ( const String &  val )

static

Checks the String is a valid number value.

isUseLocale()

inlinestatic

parseAngle()

static Radian Ogre::StringConverter::parseAngle ( const String &  val, Radian  defaultValue = Radian(0)  )

inlinestatic

Converts a String to a Angle.

Returns

0.0 if the value could not be parsed, otherwise the Angle version of the String.

parseBool()

static bool Ogre::StringConverter::parseBool ( const String &  val, bool  defaultValue = 0, bool *  error = NULL  )

static

Converts a String to a boolean.

Remarks

Returns true if case-insensitive match of the start of the string matches "true", "yes", "1", or "on", false if "false", "no", "0" or "off".

parseColourBuffer()

static ColourBufferType Ogre::StringConverter::parseColourBuffer ( const String &  val, ColourBufferType  defaultValue = CBT_BACK  )
