- All Implemented Interfaces:
CopyConstructorClonable,java.io.Serializable
- Direct Known Subclasses:
TypedMetaProperty
public class MetaProperty extends java.lang.Object implements java.io.Serializable, CopyConstructorClonable
The base MetaProperty class. A metaproperty represets a setting. It has a name and a value. While not marked as abstract, there are currently no public constructors. The reason is that everything should ideally be a TypedMetaProperty.A WellKnownMetaProperty is a special typed meta property defining a common setting. Ideally each stored setting would have a defined WellKnownMetaProperty, since they have utilities to make it easier to retrieve/set setting values in a type safe way.
Not-yet-implemented idea: A MetaProperty can be marked as Immutable, in which case its value cannot be changed and it cannot be altered/replaced/removed from a collection. The purpose of of immutable properties is to allow subclasses to enforce certain settings. By having immutable settings we could easily merge between StandardGroup and HistoricalGroup without worry. Another possible flag is REQUIRED (can't be removed)
