All Implemented Interfaces:

Iterable<T>, Collection<T>

public class TypeFilterableList<T>
extends AbstractCollection<T>

A collection allowing getting all elements of a specific type. Backed by ArrayLists.

This implementation is not efficient for frequent modifications. You shouldn't use this if you don't call getAllOfType(Class).
