/**

* <p>This <code>ProtectionDomain</code> class encapsulates the characteristics
|
||||
* of a domain, which encloses a set of classes whose instances are granted a
|
||||
* set of permissions when being executed on behalf of a given set of
|
||||
* <i>Principals</i>.
|
||||
*
|
||||
* <p>A static set of permissions can be bound to a <code>ProtectionDomain</code>
|
||||
* when it is constructed; such permissions are granted to the domain regardless
|
||||
* of the {@link Policy} in force. However, to support dynamic security
|
||||
* policies, a <code>ProtectionDomain</code> can also be constructed such that
|
||||
* it is dynamically mapped to a set of permissions by the current {@link
|
||||
* Policy} whenever a permission is checked.</p>
|
||||
* This class represents a group of classes, along with their granted
|
||||
* permissions. The classes are identified by a {@link CodeSource}. Thus, any
|
||||
* class loaded from the specified {@link CodeSource} is treated as part of
|
||||
* this domain. The set of permissions is represented by an instance of
|
||||
* {@link PermissionCollection}.
|
||||
*
|
||||
* <p>Every class in the system will belong to one and only one
|
||||
* <code>ProtectionDomain</code>.</p>
