+/**
+ * FSTArraySortedDictionary is an array backed implementation of FSTImmutableSortedDictionary.
+ *
+ * You should not use this class directly. You should use FSTImmutableSortedDictionary.
+ *
+ * FSTArraySortedDictionary uses arrays and linear lookups to achieve good memory efficiency while
+ * maintaining good performance for small collections. It also uses fewer allocations than a
+ * comparable red black tree. To avoid degrading performance with increasing collection size it
+ * will automatically convert to a FSTTreeSortedDictionary after an insert call above a certain
+ * threshold.
