Constructs a new instance of Permission with its name.
| name | the name of the permission. |
|---|
Invokes checkPermission(Permission) with this permission as its argument. This method implements the Guard interface.
| obj | as specified in checkGuard(Object) but ignored in this implementation. |
|---|
| SecurityException | if this permission is not granted. |
|---|
Compares the specified object with this Permission for equality
and returns true if the specified object is equal, false
otherwise.
The implies(Permission) method should be used for making access control checks.
| obj | object to be compared for equality with this Permission. |
|---|
true if the specified object is equal to this Permission, otherwise false.Returns a comma separated string identifying the actions associated with this permission. The returned actions are in canonical form. For example:
sp0 = new SocketPermission("www.google.com", "connect,resolve")
sp1 = new SocketPermission("www.google.com", "resolve,connect")
sp0.getActions().equals(sp1.getActions()) //yields true
Both permissions return "connect,resolve" (in that order) if #getActions() is invoked. Returns an empty String, if no actions are
associated with this permission.Returns the name of this permission.
Returns the hash code value for this Permission. Returns the same
hash code for Permissions that are equal to each other as
required by the general contract of hashCode().
Permission.Indicates whether the specified permission is implied by this permission. The AccessController uses this method to check whether permission protected access is allowed with the present policy.
| permission | the permission to check against this permission. |
|---|
true if the specified permission is implied by this
permission, false otherwise.Returns a specific PermissionCollection container for permissions
of this type. Returns null if any permission collection can be
used.
Subclasses may override this method to return an appropriate collection for the specific permissions they implement.
null if any
permission collection can be used.Returns a string containing a concise, human-readable description of the
this Permission including its name and its actions.
