java.lang.Objectjava.security.ProtectionDomain
public class ProtectionDomain
This class represents a group of classes, along with their granted
permissions. The classes are identified by a CodeSource. Thus, any
class loaded from the specified CodeSource is treated as part of
this domain. The set of permissions is represented by an instance of
PermissionCollection.
Every class in the system will belong to one and only one
ProtectionDomain.
| Constructor Summary | |
|---|---|
ProtectionDomain(CodeSource codesource,
PermissionCollection permissions)
Initializes a new instance of ProtectionDomain representing
the specified CodeSource and set of permissions. |
|
ProtectionDomain(CodeSource codesource,

ClassLoader classloader,
Principal[] principals)
This method initializes a new instance of ProtectionDomain
given its CodeSource, granted permissions, associated
ClassLoader and Principals. |

public ProtectionDomain(CodeSource codesource,
PermissionCollection permissions)
ProtectionDomain representing
the specified CodeSource and set of permissions. No permissions
can be added later to the PermissionCollection and this contructor
will call the setReadOnly method on the specified set of
permissions.

public ProtectionDomain(CodeSource codesource,
PermissionCollection permissions,
ClassLoader classloader,

ProtectionDomain
given its CodeSource, granted permissions, associated
ClassLoader and Principals.
Similar to the previous constructor, if the designated set of
permissions is not null, the setReadOnly method
is called on that set.
