+/**
+ * ArrayMap is a generic key->value mapping data structure that is
+ * designed to be more memory efficient than a traditional {@link java.util.HashMap}.
+ * It keeps its mappings in an array data structure -- an integer array of hash
+ * codes for each item, and an Object array of the key/value pairs. This allows it to
+ * avoid having to create an extra object for every entry put in to the map, and it
+ * also tries to control the growth of the size of these arrays more aggressively
+ * (since growing them only requires copying the entries in the array, not rebuilding
+ * a hash map).
+ *
+ * <p>Note that this implementation is not intended to be appropriate for data structures
+ * that may contain large numbers of items. It is generally slower than a traditional
+ * HashMap, since lookups require a binary search and adds and removes require inserting
+ * and deleting entries in the array. For containers holding up to hundreds of items,
+ * the performance difference is not significant, less than 50%. For larger numbers of items
+ * this data structure should be avoided.</p>
+ *
+ * <p><b>Note:</b> unlike {@link java.util.HashMap}, this container does not support
+ * null keys.</p>
+ *
+ * <p>Because this container is intended to better balance memory use, unlike most other
+ * standard Java containers it will shrink its array as items are removed from it. Currently
+ * you have no control over this shrinking -- if you set a capacity and then remove an
+ * item, it may reduce the capacity to better match the current size. In the future an
+ * explicitly call to set the capacity should turn off this aggressive shrinking behavior.</p>
