add	back to summary
public boolean add(T t) Overrides java.util.AbstractCollection.add. Implements java.util.Set.add, java.util.Collection.add. Doc from java.util.Set.add. Adds the specified element to this set if it is not already present (optional operation). More formally, adds the specified element `e` to this set if the set contains no element `e2` such that `Objects.equals(e, e2)`. If this set already contains the element, the call leaves the set unchanged and returns `false`. In combination with the restriction on constructors, this ensures that sets never contain duplicate elements. The stipulation above does not imply that sets must accept all elements; sets may refuse to add any particular element, including `null`, and throw an exception, as described in the specification for `Collection.add`. Individual set implementations should clearly document any restrictions on the elements that they may contain. Parameters t:T element to be added to this set Returns:boolean `true` if this set did not already contain the specified element Annotations @Override

public boolean add(T t)

Overrides java.util.AbstractCollection.add.

Implements java.util.Set.add, java.util.Collection.add.

Doc from java.util.Set.add.

Adds the specified element to this set if it is not already present (optional operation). More formally, adds the specified element e to this set if the set contains no element e2 such that Objects.equals(e, e2). If this set already contains the element, the call leaves the set unchanged and returns false. In combination with the restriction on constructors, this ensures that sets never contain duplicate elements.

The stipulation above does not imply that sets must accept all elements; sets may refuse to add any particular element, including null, and throw an exception, as described in the specification for Collection.add.

public boolean addAll(Collection<? extends T> c) Overrides java.util.AbstractCollection.addAll. Implements java.util.Set.addAll, java.util.Collection.addAll. Doc from java.util.Set.addAll. Adds all of the elements in the specified collection to this set if they're not already present (optional operation). If the specified collection is also a set, the `addAll` operation effectively modifies this set so that its value is the union of the two sets. The behavior of this operation is undefined if the specified collection is modified while the operation is in progress. Parameters c:Collection<? extends T> collection containing elements to be added to this set Returns:boolean `true` if this set changed as a result of the call Annotations @Override

public void addListener(InvalidationListener invalidationListener) Implements javafx.beans.Observable.addListener. Doc from javafx.beans.Observable.addListener. Adds an `InvalidationListener` which will be notified whenever the `Observable` becomes invalid. If the same listener is added more than once, then it will be notified more than once. That is, no check is made to ensure uniqueness. Note that the same actual `InvalidationListener` instance may be safely registered for different `Observables`. The `Observable` stores a strong reference to the listener which will prevent the listener from being garbage collected and may result in a memory leak. It is recommended to either unregister a listener by calling `removeListener` after use or to use an instance of `WeakInvalidationListener` avoid this situation. Parameters invalidationListener:InvalidationListener The listener to register Annotations @Override
