Declaration
class func weakToStrongObjects() -> NSMapReturn Value
A new map table object which has weak references to the keys and strong references to the values.
Discussion
Use of weak-to-strong map tables is not recommended. The strong values for weak keys which get zeroed out continue to be maintained until the map table resizes itself.
