convert

public Object convert(Object obj)

Description copied from class: Domain

Try to convert an object to a corresponding object of this type. Note that this is not a typecast method, instead, it is intended to provide a fallback to convert objects of the wrong type to the correct one. (This could be used, for example, after Attribute.setValue() throws a TypeException.)

Overrides:

convert in class Domain

Parameters:

obj - The object to convert.

Returns:

The other object converted to one of this domain. If the conversion is not possible, or not implemented, returns null.
