T - the instance typepublic class InstanceFilter<T> extends Object
Subclasses may want to override match(Object, Object) to provide
 a custom matching algorithm.

public InstanceFilter(@Nullable Collection<? extends T> includes, @Nullable Collection<? extends T> excludes, boolean matchIfEmpty)
A particular element will match if it "matches" the one of the element in the includes list and does not match one of the element in the excludes list.
Subclasses may redefine what matching means. By default, an element match with
 another if it is equals according to Object.equals(Object)
 
If both collections are empty, matchIfEmpty defines if
 an element matches or not.

 If the candidates collection is null, returns false.
