It contains the methods necessary for the creation, * registration, and deletion of MBeans as well as the access methods * for registered MBeans. This is the core component of the JMX * infrastructure.</p> * * <p>User code does not usually implement this interface. Instead, * an object that implements this interface is obtained with one of * the methods in the {@link javax.management.MBeanServerFactory} class.</p> * * <p>Every MBean which is added to the MBean server becomes * manageable: its attributes and operations become remotely * accessible through the connectors/adaptors connected to that MBean * server. A Java object cannot be registered in the MBean server * unless it is a JMX compliant MBean.</p> * * <p id="notif">When an MBean is registered or unregistered in the * MBean server a {@link javax.management.MBeanServerNotification * MBeanServerNotification} Notification is emitted. To register an * object as listener to MBeanServerNotifications you should call the * MBean server method {@link #addNotificationListener * addNotificationListener} with <CODE>ObjectName</CODE> the * <CODE>ObjectName</CODE> of the {@link * javax.management.MBeanServerDelegate MBeanServerDelegate}. This * <CODE>ObjectName</CODE> is: <BR> * <CODE>JMImplementation:type=MBeanServerDelegate</CODE>.</p> * * <p>An object obtained from the {@link * MBeanServerFactory#createMBeanServer(String) createMBeanServer} or * {@link MBeanServerFactory#newMBeanServer(String) newMBeanServer} * methods of the {@link MBeanServerFactory} class applies security * checks to its methods, as follows.</p> * * <p>First, if there is no security manager ({@link * System#getSecurityManager()} is null), then an implementation of * this interface is free not to make any checks.</p> * * <p>Assuming that there is a security manager, or that the * implementation chooses to make checks anyway, the checks are made * as detailed below. In what follows, and unless otherwise specified, * {@code className} is the * string returned by {@link MBeanInfo#getClassName()} for the target * MBean.</p> * * <p>If a security check fails, the method throws {@link * SecurityException}.</p> * * <p>For methods that can throw {@link InstanceNotFoundException}, * this exception is thrown for a non-existent MBean, regardless of * permissions. This is because a non-existent MBean has no * <code>className</code>.</p> * * <ul> * * <li><p>For the {@link #invoke invoke} method, the caller's * permissions must imply {@link * MBeanPermission#MBeanPermission(String,String,ObjectName,String) * MBeanPermission(className, operationName, name, "invoke")}.</p> * * <li><p>For the {@link #getAttribute getAttribute} method, the * caller's permissions must imply {@link * MBeanPermission#MBeanPermission(String,String,ObjectName,String) * MBeanPermission(className, attribute, name, "getAttribute")}.</p> * * <li><p>For the {@link #getAttributes getAttributes} method, the * caller's permissions must imply {@link * MBeanPermission#MBeanPermission(String,String,ObjectName,String) * MBeanPermission(className, null, name, "getAttribute")}. * Additionally, for each attribute <em>a</em> in the {@link * AttributeList}, if the caller's permissions do not imply {@link * MBeanPermission#MBeanPermission(String,String,ObjectName,String) * MBeanPermission(className, <em>a</em>, name, "getAttribute")}, the * MBean server will behave as if that attribute had not been in the * supplied list.</p> * * <li><p>For the {@link #setAttribute setAttribute} method, the * caller's permissions must imply {@link * MBeanPermission#MBeanPermission(String,String,ObjectName,String) * MBeanPermission(className, attrName, name, "setAttribute")}, where * <code>attrName</code> is {@link Attribute#getName() * attribute.getName()}.</p> * * <li><p>For the {@link #setAttributes setAttributes} method, the * caller's permissions must imply {@link * MBeanPermission#MBeanPermission(String,String,ObjectName,String) * MBeanPermission(className, null, name, "setAttribute")}. * Additionally, for each attribute <em>a</em> in the {@link * AttributeList}, if the caller's permissions do not imply {@link * MBeanPermission#MBeanPermission(String,String,ObjectName,String) * MBeanPermission(className, <em>a</em>, name, "setAttribute")}, the * MBean server will behave as if that attribute had not been in the * supplied list.</p> * * <li><p>For the <code>addNotificationListener</code> methods, * the caller's permissions must imply {@link * MBeanPermission#MBeanPermission(String,String,ObjectName,String) * MBeanPermission(className, null, name, * "addNotificationListener")}.</p> * * <li><p>For the <code>removeNotificationListener</code> methods, * the caller's permissions must imply {@link * MBeanPermission#MBeanPermission(String,String,ObjectName,String) * MBeanPermission(className, null, name, * "removeNotificationListener")}.</p> * * <li><p>For the {@link #getMBeanInfo getMBeanInfo} method, the * caller's permissions must imply {@link * MBeanPermission#MBeanPermission(String,String,ObjectName,String) * MBeanPermission(className, null, name, "getMBeanInfo")}.</p> * * <li><p>For the {@link #getObjectInstance getObjectInstance} method, * the caller's permissions must imply {@link * MBeanPermission#MBeanPermission(String,String,ObjectName,String) * MBeanPermission(className, null, name, "getObjectInstance")}.</p> * * <li><p>For the {@link #isInstanceOf isInstanceOf} method, the * caller's permissions must imply {@link * MBeanPermission#MBeanPermission(String,String,ObjectName,String) * MBeanPermission(className, null, name, "isInstanceOf")}.</p> * * <li><p>For the {@link #queryMBeans queryMBeans} method, the * caller's permissions must imply {@link * MBeanPermission#MBeanPermission(String,String,ObjectName,String) * MBeanPermission(null, null, null, "queryMBeans")}. * Additionally, for each MBean <em>n</em> that matches <code>name</code>, * if the caller's permissions do not imply {@link * MBeanPermission#MBeanPermission(String,String,ObjectName,String) * MBeanPermission(className, null, <em>n</em>, "queryMBeans")}, the * MBean server will behave as if that MBean did not exist.</p> * * <p>Certain query elements perform operations on the MBean server. * If the caller does not have the required permissions for a given * MBean, that MBean will not be included in the result of the query. * The standard query elements that are affected are {@link * Query#attr(String)}, {@link Query#attr(String,String)}, and {@link * Query#classattr()}.</p> * * <li><p>For the {@link #queryNames queryNames} method, the checks * are the same as for <code>queryMBeans</code> except that * <code>"queryNames"</code> is used instead of * <code>"queryMBeans"</code> in the <code>MBeanPermission</code> * objects.
