Class DefaultBehaviorProvider<T>

java.lang.Object
  org.opends.server.admin.DefaultBehaviorProvider<T>

Type Parameters:

T - The type of values represented by this provider.

Direct Known Subclasses:

AbsoluteInheritedDefaultBehaviorProvider, AliasDefaultBehaviorProvider, DefinedDefaultBehaviorProvider, RelativeInheritedDefaultBehaviorProvider, UndefinedDefaultBehaviorProvider

public abstract class DefaultBehaviorProvider<T>
extends java.lang.Object

An interface for determining the default behavior of a property. A property exhibits default behavior when it has no values defined. There are four different types of default behavior:

1. there is no default behavior - e.g. leaving a "description" unset has no side-effects. This default behavior is represented using the UndefinedDefaultBehaviorProvider implementation
2. the property defaults to one or more real values of the property. This default behavior is represented using the DefinedDefaultBehaviorProvider implementation
3. the property defaults to some special behavior that cannot be represented using real property values. This default behavior is represented using the AliasDefaultBehaviorProvider implementation
4. the property inherits its values from property held in another managed object (e.g. the parent managed object). This default behavior is represented using the AbsoluteInheritedDefaultBehaviorProvider and RelativeInheritedDefaultBehaviorProvider implementations.

An application can perform actions based on the type of the default behavior by implementing the DefaultBehaviorProviderVisitor interface.
