IntersectionObservableList (com.iamsoft:iamsoft-fxutils 11.0.0-SNAPSHOT API)

java.lang.Object
- java.util.AbstractCollection<E>
- - java.util.AbstractList<E>
  - - javafx.collections.ObservableListBase<T>
    - - com.iamsoft.util.ui.javafx.collections.IntersectionObservableList<T>

Type Parameters:

T - Type of item contained within list.

All Implemented Interfaces:

Iterable<T>, Collection<T>, List<T>, javafx.beans.Observable, javafx.collections.ObservableList<T>
```
public class IntersectionObservableList<T>
extends javafx.collections.ObservableListBase<T>
```
List comprising intersection of zero to many child lists. Note that list is not updated until component list events are processed. Thus, listeners to component list cannot assume that intersection list is valid.
