Filters for selecting just the elements of interest from a collection of elements. The returned sets and lists are new collections and do use the argument as a backing store. The methods in this class do not make any attempts to guard against concurrent modifications of the arguments. The returned sets and lists are mutable but unsafe for concurrent access. A returned set has the same iteration order as the argument set to a method.
If iterables and sets containing
null are passed as arguments to methods in this class, a
NullPointerException will be thrown.
Note that a static import statement can make the text of calls to the methods in this class more concise; for example:
import static javax.lang.model.util.ElementFilter.*;
List<VariableElement> fs = fieldsIn(someClass.getEnclosedElements());
