Class ElementFilter

java.lang.Object

javax.lang.model.util.ElementFilter

public class ElementFilter
extends Object

Filters for selecting just the elements of interest from a collection of elements. The returned sets and lists are new collections that do not use the argument collection 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 and unsafe for concurrent access. A returned set from a method has the same iteration order as the argument set to the method.

If iterables or sets containing null are passed as arguments to methods in this class, a NullPointerException will be thrown.
