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. If typeInfo' 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().
