Serializable, Guard

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:
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").

API Note:
This permission cannot be used for controlling access to resources as the Security Manager is no longer supported.

  • Method Details Link icon

    • implies Link icon

      public boolean implies(Permission p)

      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 Link icon

      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.
      Overrides:
      equals in class BasicPermission
      Parameters:
      obj - the object we are testing for equality with this object.
      Returns:
      true if the objects are equal.
