Class Permissions
- Serializable
This class is a heterogeneous collection of permissions. It is
organized as a collection of PermissionCollection's stored
in a hashtable. Each individual PermissionCollection
contains permissions of a single type. If a specific type of
Permission does not provide a collection type to use
via its newPermissionCollection method, then a default
collection type which stores its permissions in a hash table will be
used.

a default collection, which stores in permissions in a hash table, will
be used.
