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").

Methods

implies

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

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.
