TypeString 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.
Type returns
true.
isValidValueImpl in class Typevalue - 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)
TypeString 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 Type.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
Type.isValidValueImpl(String) without getting an exception.

throws IllegalArgumentException,
ClassCastException,
TypeValueException
TypeType.getValueClass()). Also, it may have to fall within a
certain range of valid values, depending on the type.
The default implementation of this method in class Type does
the following:
value == null then it throws an
IllegalArgumentException;
getValueClass().isInstance(value) == false then
it throws a ClassCastException;
