Examples of edu.umd.cloud9.util.map.HMapIL$Entry

edu.umd.cloud9.util.map.HMapIL
Hash-based implementation of the MapIL interface. {@link MapIL} isa specialized variant the standard Java {@link Map} interface, except thatthe keys are hard coded as ints and values are hard coded as longs for efficiency reasons. This implementation was adapted from {@link HashMap}version 1.73, 03/13/07. See this benchmark for an efficiency comparison.
