Class ImmutableList<E>

java.lang.Object

java.util.AbstractCollection<E>

com.intellij.util.containers.ImmutableList<E>

All Implemented Interfaces:

java.lang.Iterable<E>, java.util.Collection<E>, java.util.List<E>

Direct Known Subclasses:

GraphCommitImpl

public abstract class ImmutableList<E>
extends java.util.AbstractCollection<E>
implements java.util.List<E>

A base class for immutable list implementations.

Copied from AbstractList with modCount field removed, because the implementations are supposed to be immutable, so it makes no sense to waste memory on modCount.
