Method Detail

newProperty

public Property newProperty(MethodMeta mm)
                     throws DecorationException

Description copied from interface: StatePrototype

instantiate new Property for given MethodMeta

This is a factory method used by Decorator during instantiation of new State object

Parameters:

mm - to be used as underlying MethodMeta for that Property

Throws:

DecorationException - in case of internal error

sort

public void sort(int leadField,
                 int order)

Description copied from class: AbstractState

sort the objects directly in the underlying collection

Specified by:

sort in interface State

Overrides:

sort in class AbstractState

Parameters:

leadField - is one of State.SORT_BY_NAME,State.SORT_BY_DESC or State.SORT_BY_VALUE

order - is one of State.SORT_ASC or State.SORT_DESC

update

public void update()
            throws DecorationException

Description copied from interface: State

Update the state of the object.

The idea of this method is to allow for state update is that is possible. This way State objects became reusable.

This method is subject to different implementation variations. For example, snapshot type of States might be able to refresh state but dynamic generally do not need this.

Throws:

DecorationException
