Class BimodalMap<K,V extends @Nullable Object>

java.lang.Object

com.ibm.wala.util.collections.BimodalMap<K,V>

All Implemented Interfaces:

Map<K,V>

public class BimodalMap<K,V extends @Nullable Object>
extends Object
implements Map<K,V>

This implementation of Map chooses between one of two implementations, depending on the size of the map.
