Generates a content binding between an javafx.collections.ObservableSet and a java.util.Set.

A content binding ensures that the Set contains the same elements as the ObservableSet. If the content of the ObservableSet changes, the Set will be updated automatically.

Once a Set is bound to an ObservableSet, the Set must not be changed directly anymore. Doing so would lead to unexpected results.

A content-binding can be removed with unbindContent(Object, Object).

Parameters:

<E>		the type of the Set elements
set1		the Set
set2		the ObservableSet

Exceptions:

NullPointerException		if one of the sets is null
IllegalArgumentException		if set1 == set2
