public abstract class BasicPermission extends Permission implements Serializable
BasicPermission class extends the Permission class, and can be used as the base class for permissions that want to follow the same naming convention as BasicPermission. The name for a BasicPermission is the name of the given permission (for example, "exit", "setFactory", "print.queueJob", etc.). The naming convention follows the hierarchical property naming convention. An asterisk may appear by itself, or if immediately preceded by a "." may appear at the end of the name, to signify a wildcard match. For example, "*" and "java.*" signify a wildcard match, while "*java", "a*b", and "java*" do not.
The action string (inherited from Permission) is unused. Thus, BasicPermission is commonly used as the base class for "named" permissions (ones that contain a name but no actions list; you either have the named permission or you don't.) Subclasses may implement actions on top of BasicPermission, if desired.
| Constructor | Description |
|---|---|
BasicPermission |
Creates a new BasicPermission with the specified name. |
BasicPermission |
Creates a new BasicPermission object with the specified name. |
| Modifier and Type | Method | Description |
|---|---|---|
boolean |
equals |
Checks two BasicPermission objects for equality. |
String |
getActions() |
Returns the canonical string representation of the actions, which currently is the empty string "", since there are no actions for a BasicPermission. |
int |
hashCode() |
Returns the hash code value for this object. |
boolean |
implies |
Checks if the specified permission is "implied" by this object. |
PermissionCollection |
newPermissionCollection() |
Returns a new PermissionCollection object for storing BasicPermission objects. |
checkGuard, getName, toString
public BasicPermission(String name)
BasicPermission with the specified name. Name is the symbolic name of the permission, such as "setFactory", "print.queueJob", or "topLevelWindow", etc.name - the name of the BasicPermission.NullPointerException - if name is null.IllegalArgumentException - if name is empty.public BasicPermission(String name, String actions)
BasicPermission object with the specified name. The name is the symbolic name of the BasicPermission, and the actions String is currently unused.name - the name of the BasicPermission.actions - ignored.NullPointerException - if name is null.IllegalArgumentException - if name is empty.public boolean implies(Permission p)
More specifically, this method returns true if:
p's class is the same as this object's class, and p's name equals or (in the case of wildcards) is implied by this object's name. For example, "a.b.*" implies "a.b.c". implies in class Permission
p - the permission to check against.true if the passed permission is equal to or implied by this permission, false otherwise.public boolean equals(Object obj)
BasicPermission objects for equality. Checks that obj's class is the same as this object's class and has the same name as this object.equals in class Permission
obj - the object we are testing for equality with this object.true if obj's class is the same as this object's class and has the same name as this BasicPermission object, false otherwise.public int hashCode()
getName().hashCode(), where getName is from the Permission superclass.hashCode in class Permission
public String getActions()
BasicPermission.getActions in class Permission
public PermissionCollection newPermissionCollection()
PermissionCollection object for storing BasicPermission objects. BasicPermission objects must be stored in a manner that allows them to be inserted in any order, but that also enables the PermissionCollection.implies(java.security.Permission) method to be implemented in an efficient (and consistent) manner.
newPermissionCollection in class Permission
PermissionCollection object suitable for storing BasicPermission objects.
