<pre>public abstract class <span class="typeNameLabel">ObservableListBase<E></span>
extends <a href="https://docs.oracle.com/javase/8/docs/api/java/util/AbstractList.html?is-external=true" title="class or interface in java.util">AbstractList</a><E>
implements <a href="../../javafx/collections/ObservableList.html" title="interface in javafx.collections">ObservableList</a><E></pre>
<div class="block">Abstract class that serves as a base class for <a href="../../javafx/collections/ObservableList.html" title="interface in javafx.collections"><code>ObservableList</code></a> implementations.
The base class provides two functionalities for the implementing classes.
<ul>
<li> Listener handling by implementing <code>addListener</code> and <code>removeListener</code> methods.
<a href="../../javafx/collections/ObservableListBase.html#fireChange-javafx.collections.ListChangeListener.Change-"><code>fireChange(javafx.collections.ListChangeListener.Change)</code></a> method is provided
for notifying the listeners with a <code>Change</code> object.
<li> Methods for building up a <a href="../../javafx/collections/ListChangeListener.Change.html" title="class in javafx.collections"><code>ListChangeListener.Change</code></a> object. There are various methods called
<code>next*</code>, like <a href="../../javafx/collections/ObservableListBase.html#nextAdd-int-int-"><code>nextAdd(int, int)</code></a> for new items in the lists or <a href="../../javafx/collections/ObservableListBase.html#nextRemove-int-E-"><code>nextRemove(int, java.lang.Object)</code></a> for
an item being removed from the list.
<p><strong>These methods must be always enclosed in <a href="../../javafx/collections/ObservableListBase.html#beginChange--"><code>beginChange()</code></a> and <a href="../../javafx/collections/ObservableListBase.html#endChange--"><code>endChange()</code></a> block.</strong>
<p>See the example below.
</ul>
The following example shows how the Change build-up works:
<pre>
<strong>public void</strong> removeOddIndexes() {
beginChange();
try {
for (<strong>int</strong> i = 1; i < size(); ++i) {
remove(i);
}
} finally {
endChange();
}
}
<strong>public void</strong> remove(<strong>int</strong> i) {
beginChange();
try {
<strong>E</strong> removed = ... //do some stuff that will actually remove the element at index i
nextRemove(i, removed);
} finally {
endChange();
}
}
</pre>
The <code>try</code>/<code>finally</code> blocks in the example are needed only if there's a possibility for an exception to occur
inside a <code>beginChange()</code> / <code>endChange()</code> block
<p>
Note: If you want to create modifiable <a href="../../javafx/collections/ObservableList.html" title="interface in javafx.collections"><code>ObservableList</code></a> implementation, consider
using <a href="../../javafx/collections/ModifiableObservableListBase.html" title="class in javafx.collections"><code>ModifiableObservableListBase</code></a> as a superclass.
<p>
Note: In order to create list with sequential access, you should override <a href="https://docs.oracle.com/javase/8/docs/api/java/util/AbstractList.html?is-external=true#listIterator--" title="class or interface in java.util"><code>AbstractList.listIterator()</code></a>,
<a href="https://docs.oracle.com/javase/8/docs/api/java/util/AbstractList.html?is-external=true#iterator--" title="class or interface in java.util"><code>AbstractList.iterator()</code></a> methods and use them in <a href="https://docs.oracle.com/javase/8/docs/api/java/util/AbstractList.html?is-external=true#get-int-" title="class or interface in java.util"><code>AbstractList.get(int)</code></a>, <a href="https://docs.oracle.com/javase/8/docs/api/java/util/AbstractCollection.html?is-external=true#size--" title="class or interface in java.util"><code>AbstractCollection.size()</code></a> and other methods accordingly.</div>
