All Implemented Interfaces:

Serializable, Guard

public class MBeanServerPermission
extends BasicPermission

Disabled: no SafeJ information.

A Permission to perform actions related to MBeanServers. The name of the permission specifies the operation requested or granted by the permission. For a granted permission, it can be * to allow all of the MBeanServer operations specified below. Otherwise, for a granted or requested permission, it must be one of the following:

createMBeanServer

Create a new MBeanServer object using the method MBeanServerFactory.createMBeanServer() or MBeanServerFactory.createMBeanServer(java.lang.String).

findMBeanServer

Find an MBeanServer with a given name, or all MBeanServers in this JVM, using the method MBeanServerFactory.findMBeanServer(java.lang.String).

newMBeanServer

Create a new MBeanServer object without keeping a reference to it, using the method MBeanServerFactory.newMBeanServer() or MBeanServerFactory.newMBeanServer(java.lang.String).

releaseMBeanServer

Remove the MBeanServerFactory's reference to an MBeanServer, using the method MBeanServerFactory.releaseMBeanServer(javax.management.MBeanServer).

The name of the permission can also denote a list of one or more comma-separated operations. Spaces are allowed at the beginning and end of the name and before and after commas.

MBeanServerPermission("createMBeanServer") implies MBeanServerPermission("newMBeanServer").

Constructor Detail

MBeanServerPermission

public MBeanServerPermission(String name)

Class is disabled.

Create a new MBeanServerPermission with the given name.

This constructor is equivalent to MBeanServerPermission(name,null).

Parameters:

name - the name of the granted permission. It must respect the constraints spelt out in the description of the MBeanServerPermission class.

Throws:

NullPointerException - if the name is null.

IllegalArgumentException - if the name is not * or one of the allowed names or a comma-separated list of the allowed names.

MBeanServerPermission

public MBeanServerPermission(String name,
                             String actions)

Class is disabled.

Create a new MBeanServerPermission with the given name.

Parameters:

name - the name of the granted permission. It must respect the constraints spelt out in the description of the MBeanServerPermission class.

actions - the associated actions. This parameter is not currently used and must be null or the empty string.

Throws:

NullPointerException - if the name is null.

IllegalArgumentException - if the name is not * or one of the allowed names or a comma-separated list of the allowed names, or if actions is a non-null non-empty string.

NullPointerException - if name is null.

IllegalArgumentException - if name is empty or if arguments are invalid.

Method Detail

hashCode

public int hashCode()

Suppressed. default deny

Description copied from class: BasicPermission

Returns the hash code value for this object. The hash code used is the hash code of the name, that is, getName().hashCode(), where getName is from the Permission superclass.

Overrides:

hashCode in class BasicPermission

Returns:

a hash code value for this object.

See Also:

Object.equals(java.lang.Object), System.identityHashCode(java.lang.Object)

implies

public boolean implies(Permission p)

Class is disabled.

Checks if this MBeanServerPermission object "implies" the specified permission.

More specifically, this method returns true if:

• p is an instance of MBeanServerPermission,
• p's target names are a subset of this object's target names

The createMBeanServer permission implies the newMBeanServer permission.

Overrides:

implies in class BasicPermission

Parameters:

p - the permission to check against.

Returns:

true if the specified permission is implied by this object, false if not.

equals

public boolean equals(Object obj)

Class is disabled.

Checks two MBeanServerPermission objects for equality. Checks that obj is an MBeanServerPermission, and represents the same list of allowable actions as this object.

Overrides:

equals in class BasicPermission

Parameters:

obj - the object we are testing for equality with this object.

Returns:

true if the objects are equal.

Object.hashCode(), HashMap

newPermissionCollection

public PermissionCollection newPermissionCollection()

Suppressed. default deny

Description copied from class: BasicPermission

Returns a new 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 method to be implemented in an efficient (and consistent) manner.

Overrides:

newPermissionCollection in class BasicPermission

Returns:

a new PermissionCollection object suitable for storing BasicPermissions.
