public class MBeanServerPermission extends BasicPermission
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:
MBeanServerFactory.createMBeanServer()
or MBeanServerFactory.createMBeanServer(java.lang.String)
. MBeanServerFactory.findMBeanServer(java.lang.String)
. MBeanServerFactory.newMBeanServer()
or MBeanServerFactory.newMBeanServer(java.lang.String)
. MBeanServerFactory.releaseMBeanServer(javax.management.MBeanServer)
. MBeanServerPermission("createMBeanServer")
implies MBeanServerPermission("newMBeanServer")
.
public MBeanServerPermission(String name)

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

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.

Object.equals(java.lang.Object)
, System.identityHashCode(java.lang.Object)
public boolean implies(Permission p)
Checks if this MBeanServerPermission object "implies" the specified permission.
More specifically, this method returns true if:
The createMBeanServer
permission implies the newMBeanServer
permission.

p
- the permission to check against.public boolean equals(Object obj)
Checks two MBeanServerPermission objects for equality. Checks that obj is an MBeanServerPermission, and represents the same list of allowable actions as this object.

obj
- the object we are testing for equality with this object.Object.hashCode()

public PermissionCollection newPermissionCollection()
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.
