Method Detail

• hashCode

  public int hashCode()

  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.

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

• 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.

  Object.hashCode(), HashMap

• newPermissionCollection

  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.

  Overrides:

  newPermissionCollection in class BasicPermission

  Returns:

  a new PermissionCollection object suitable for storing BasicPermissions.
