Class SimpleIndexer<E>

java.lang.Object
pascal.taie.util.SimpleIndexer<E>
All Implemented Interfaces:
Serializable, Indexer<E>
public class SimpleIndexer<E> extends Object implements Indexer<E>
A simple map and list based implementation of Indexer. The indexes of the objects are same as their indexes in the list.

If getIndex(Object) is called with an object that was absent in this indexer, it will be added to the indexer automatically. If getObject(int) is called with an index that does not map to any object, an IllegalArgumentException will be thrown.

If you want to obtain an object of its corresponding index by getObject(i), make sure that the object has been indexed by getIndex(o).
