Convert the Observable to a ComputedValue. This method should only be called if isComputedValue() returns true.

Returns:

the ComputedValue instance.

Spy.asComputedValue(arez.Observable)

getObservers

@Nonnull
java.util.List<ObserverInfo> getObservers()

Return the list of observers for the Observable. The list is an immutable copy of the observers of the Observable.

Returns:

the list of observers for Observable.

Spy.getObservers(arez.Observable)

getComponent

@Nullable
ComponentInfo getComponent()

Return the component for the Observable. This method should not be invoked if Arez.areNativeComponentsEnabled() returns false.

Returns:

the component that contains Observable if any.

See Also:

Spy.getComponent(arez.Observable)

hasAccessor

boolean hasAccessor()

Return true if the specified Observable has an accessor. This method should not be invoked if Arez.arePropertyIntrospectorsEnabled() returns false.

Returns:

true if an accessor is available.

setValue

void setValue(@Nullable
              java.lang.Object value)
       throws java.lang.Throwable
