Type Parameters

K
V

Reference-counting map based on a HashMap implementation that stores as a value a pair of value and reference counter. The class provides a reference method that takes a key and increments the reference count for the key. It also provides a de-reference method that takes a key and decrements the reference count for the key, and removes the key if the reference count reached zero. Null values are not allowed as keys.

The following tables list the members exposed by the RefCountedMap<(Of K, V>) generic type.
