List of all members.
That is the use an object as a key in the map will not prevent it from being destroyed if all other non-weak references to it are released.
The time at which the entry associated with the weak key is cleaned up is not guaranteed, it may live in the map for some time. While it is not safe to assume that the map will shrink to its absolute minimum at any point, it is safe to assume that given constant random key insertions the size of the map will initially grow and then stabilize as the keys are reclaimed.
Note: Iterating the entries may yield entries with reclaimed (NULL) keys.

Construct a thread-safe weak hash map using the specified settings.
|cInitialBuckets||the initial number of hash buckets, 0 < n|
|flLoadFactor||the acceptable load factor before resizing occurs, 0 < n, such that a load factor of 1.0 causes resizing when the number of entries exceeds the number of buckets|
|flGrowthRate||the rate of bucket growth when a resize occurs, 0 < n, such that a growth rate of 1.0 will double the number of buckets: bucketcount = bucketcount * (1 + growthrate)|

Shrink the specified bucket.
|iBucket||the bucket to shrink|
