Examples of OpenIntToDoubleHashMap

org.apache.commons.math.util.OpenIntToDoubleHashMap

Open addressed map from int to double.

This class provides a dedicated map from integers to doubles with a much smaller memory overhead than standard java.util.Map.

This class is not synchronized. The specialized iterators returned by {@link #iterator()} are fail-fast: they throw aConcurrentModificationException when they detect the map has been modified during iteration.
