SetValue()

override void Loyc.Collections.WeakKeyDictionary< TKey, TValue >.SetValue ( TKey  key, TValue  value  )

inlineprotectedvirtual

Implementation of the setter for this[].

The setter alone (without the getter) is not allowed to be virtual in C# so a separate method is required.

Implements Loyc.Collections.Impl.DictionaryBase< TKey, TValue >.

Count

override int Loyc.Collections.WeakKeyDictionary< TKey, TValue >.Count

get

Number of items in the collection.

WARNING: The count returned here may include entries for which key value objects have already been garbage collected. Call RemoveCollectedEntries to weed out collected entries and update the count accordingly.
