    • create

      public static <TT> Collection<TT> create(Collection<TT> collection, int targetResultCount, long cutOffAfterTimeMs, int cutOffAfterCount)
      Helper method to create a PermissionCheckCollection from an existing Collection
      Type Parameters:
      TT - the type of the Collection
      Parameters:
      collection - the Collection to proxy
      targetResultCount - the desired number of results or default to the collection size
      cutOffAfterTimeMs - the number of milliseconds to wait before cut-off or zero to use the system default time-based cut-off.
      cutOffAfterCount - the number of permission checks to process before cut-off or zero to use the system default count-based cut-off.
      Returns:
      a Collection of the same type but including the PermissionCheckCollection interface
