This method is called from Type.isValidValue(String)

called from that method, it is guaranteed that the argument is not
null

for this type (implementation method).
This method is not required to check the validity of the specified
value (since Type.isValidValueImpl(String)
should have been called
before) but if it does, then it may throw a TypeValueException
.
fromStringImpl
in class Type
string
- the string to convert to an instance of the value class, guaranteed
to be not null

certain range of valid values, depending on the type.
The default implementation of this method in class Type

then it throws an

then
it throws a ClassCastException
