null if and
only if value == null.protected boolean isValidValueImpl(String string)
String value is considered
valid for this type (implementation method).
This method is called from Type.isValidValue(String). When
called from that method, it is guaranteed that the argument is not
null.
isValidValueImpl in class Typestring - the String value that should be checked for validity,
never null.
true if and only if the specified String
value is valid, false otherwise.
protected Object fromStringImpl(String string)
throws TypeValueException
String to an instance of the value class
for this type (implementation method).
This method is not required to check the validity of the specified
value (since isValidValueImpl(String) should have been called
before) but if it does, then it may throw a TypeValueException.
fromStringImpl in class Typestring - the string to convert to an instance of the value class, guaranteed
to be not null and guaranteed to have been passed to
