Format a float value into a string.
Library: ilvproto
IlvFormatAccessor is used to format a value and then assign the formatted value to another accessor.
| IlvFormatAccessor::IlvFormatAccessor | ( | const char * | name, |
| const IlvValueTypeClass * | type, | ||
| const char * | formatValue, | ||
| const char * | maxCharsValue, | ||
| const char * | subacc | ||
| ) |
Initializes a new formatting accessor.
When the value specified by name is changed, it is formatted using formatValue, which must contain a formatting string as defined by the printf() C library function. The value is passed to the formatting function as a float, so the format contained in formatValue should contain a g or f specifier. The formatted string is then assigned to the accessor specified by subacc. The maxCharsValue specifies the maximum length of the formatted string. If the string is longer, it is replaced by * (star) characters. formatValue and maxCharsValue can contain a constant value, the name of another accessor, or an arithmetic expression that can contain accessor names and/or constants.
