This utility struct provides a namespace for functions that perform non-primitive operations using TypeInfo objects.
◆ parseAndValidate()
Load into the specified element the result of parsing the specified input as a value of the element->type(). Return true if input is parsed without error and the value satisfies the constraint of the specified typeInfo object (if any), and false with no effect on element otherwise. If the operation fails, a descriptive error message indicating the reason for the failure is written to the specified stream. IftypeInfo' holds no constraint that validation is considered true; nevertheless, the parse might still fail due to problems with the input format. Optionally specify inputSource indicating the source of the option text being parsed. If inputSource is not provided, input is treated as if it came from the command line. inputSource is used in handling boolean options. Boolean options supplied by command line should not have associated text, where as boolean options supplied by the environment should have the values "0", "1", "true", or "false". The behavior is undefined unless element->type() == typeInfo.type().

Return true if the specified element satisfies the constraint of the specified typeInfo object (if any), and false otherwise. Optionally specify a stream; if stream is specified and validation fails, a descriptive error message indicating the reason for the failure is written to stream. If typeInfo holds no constraint, this method returns true. The behavior is undefined unless element.type() == typeInfo.type().

Return true if the value at the specified variable satisfies the constraint of the specified typeInfo object (if any), and false otherwise. Optionally specify a stream; if stream is specified and validation fails, a descriptive error message indicating the reason for the failure is written to stream. If typeInfo holds no constraint, this method returns true. The behavior is undefined unless variable can be (validly) cast to OptionType<ENUM>::EnumToType::type * where ENUM matches typeInfo.type().
◆ tokenizeArrayEnvironmentVariable()
Load the specified tokens with the specified input broken up into substrings separated by , except that characters following '\' are not to be interpreted as separators. It is an error for input to contain a '\' that is not followed by another '\' or . Return 0 on success, and a negative value on failure.
