/**
|

* This class models a group of Java permissions. It has convenient
|
||||
* methods for determining whether or not a given permission is implied
|
||||
* by any of the permissions in this collection.
|
||||
* <p>
|
||||
* Some care must be taken in storing permissions. First, a collection of
|
||||
* the appropriate type must be created. This is done by calling the
|
||||
* <code>newPermissionCollection</code> method on an object of the
|
||||
* permission class you wish to add to the collection. If this method
|
||||
* returns <code>null</code>, any type of <code>PermissionCollection</code>
|
||||
* can be used to store permissions of that type. However, if a
|
||||
* <code>PermissionCollection</code> collection object is returned, that
|
||||
* type must be used.
|
||||
* <p>
|
||||
* The <code>PermissionCollection</code>'s returned
|
||||
* by the <code>newPermissionCollection</code> instance in a subclass of
|
||||
* <code>Permission</code> is a homogeneous collection. It only will
|
||||
* hold permissions of one specified type - instances of the class that
|
||||
* created it. Not all <code>PermissionCollection</code> subclasses
|
||||
* have to hold permissions of only one type however. For example,
|
||||
* the <code>Permissions</code> class holds permissions of many types.
|
||||
* <p>
|
||||
* Since the <code>newPermissionCollection</code> in <code>Permission</code>
|
||||
* itself returns <code>null</code>, by default a permission can be stored
|
||||
* in any type of collection unless it overrides that method to create its
|
||||
* own collection type.
