Description copied from interface: Property

Get the property's value as an object. The object type will be appropriate for the type of property. The object will either be immutable or a clone of the real object.

This method has strong semantics such that where a and b are properties of the same type, it must be true that:
b.set( a.toObject() ); a.equals(b);
In other words, the object contains all the data necessary to recreate the property's value.

Specified by:: toObject in interface Property
Specified by:: toObject in class AbstractProperty

Returns:: an Object representing the property's value
