isStale

public boolean isStale()

Description copied from interface: IObservable

Returns whether the state of this observable is stale and is expected to change soon. A non-stale observable that becomes stale will notify its stale listeners. A stale object that becomes non-stale does so by changing its state and notifying its change listeners, it does not notify its stale listeners about becoming non-stale. Clients that do not expect asynchronous changes may ignore staleness of observable objects.

Specified by:

isStale in interface IObservable

Returns:

Returns the stale state.

---

setStale

public void setStale(boolean stale)

Parameters:

stale - The stale state to set. This will fire a stale event if the given boolean is true and this observable set was not already stale.

---

setWrappedSet

protected void setWrappedSet(
Set wrappedSet)

Parameters:

wrappedSet - The wrappedSet to set.

---

fireChange

protected void fireChange()

Overrides:

fireChange in class AbstractObservable

---

dispose

public void dispose()

Description copied from interface: IObservable

Disposes of this observable object, removing all listeners registered with this object, and all listeners this object might have registered on other objects.

Specified by:

dispose in interface IObservable

Overrides:

dispose in class AbstractObservable

---

getElementType

public 
Object getElementType()

Description copied from interface: IObservableCollection

Returns the element type of this observable collection, or null if this observable collection is untyped.

Specified by:

getElementType in interface IObservableCollection

Specified by:

getElementType in interface IObservableSet

Returns:

the element type or null if untyped

---
