public class RequiredModelMBean
extends Object
implements ModelMBean, MBeanRegistration, NotificationEmitter
```
Этот класс является реализацией ModelMBean. Соответствующая реализация ModelMBean должна быть поставлена с каждым Агентом JMX, и класс нужно назвать RequiredModelMBean.
Ресурсы Java, желающие быть управляемыми, инстанцируют RequiredModelMBean, используя createMBean метод MBeanServer. Ресурс тогда устанавливает MBeanInfo и Дескрипторы для экземпляра RequiredModelMBean. Атрибуты и операции, представленные через ModelMBeanInfo для ModelMBean, доступны от MBeans, соединителей/адаптеров как другой MBeans. Через Дескрипторы значения и методы в управляемом приложении могут быть определены и отображены на атрибуты и операции ModelMBean. Это отображение может быть определено в XML отформатированный файл или динамически и программно во время выполнения.
Каждый RequiredModelMBean, который инстанцируют в MBeanServer, становится управляемым:
его атрибуты и операции становятся удаленно доступными через соединители/адаптеры, соединенные с тем MBeanServer.
Объект Java не может быть зарегистрирован в MBeanServer, если это не совместимый MBean JMX. Инстанцируя RequiredModelMBean, ресурсам гарантируют это, MBean допустим. MBeanException и RuntimeOperationsException должны быть брошены в каждый открытый метод. Это учитывает переносящиеся исключения из распределенной связи (RMI, EJB, и т.д.)

  - invoke
```
public Object invoke(String opName,
            Object[] opArgs,
            String[] sig)
              throws MBeanException,
                     ReflectionException
```
    Invokes a method on or through a RequiredModelMBean and returns the result of the method execution.
    If the given method to be invoked, together with the provided signature, matches one of RequiredModelMbean accessible methods, this one will be call. Otherwise the call to the given method will be tried on the managed resource.
    The last value returned by an operation may be cached in the operation's descriptor which is in the ModelMBeanOperationInfo's descriptor. The valid value will be in the 'value' field if there is one. If the 'currencyTimeLimit' field in the descriptor is:
    - <0 Then the value is not cached and is never valid. The operation method is invoked. The 'value' and 'lastUpdatedTimeStamp' fields are cleared.
    - =0 Then the value is always cached and always valid. The 'value' field is returned. If there is no 'value' field then the operation method is invoked for the attribute. The 'lastUpdatedTimeStamp' field and `value' fields are set to the operation's return value and the current time stamp.
    - >0 Represents the number of seconds that the 'value' field is valid. The 'value' field is no longer valid when 'lastUpdatedTimeStamp' + 'currencyTimeLimit' > Now.
      
      When 'value' is valid, 'value' is returned.
      
      When 'value' is no longer valid then the operation method is invoked. The 'lastUpdatedTimeStamp' field and `value' fields are updated.
    Note: because of inconsistencies in previous versions of this specification, it is recommended not to use negative or zero values for currencyTimeLimit. To indicate that a cached value is never valid, omit the currencyTimeLimit field. To indicate that it is always valid, use a very large number for this field.
    Specified by:
    
    invoke in interface DynamicMBean
    
    Parameters:
    opName - The name of the method to be invoked. The name can be the fully qualified method name including the classname, or just the method name if the classname is defined in the 'class' field of the operation descriptor.
    opArgs - An array containing the parameters to be set when the operation is invoked
    sig - An array containing the signature of the operation. The class objects will be loaded using the same class loader as the one used for loading the MBean on which the operation was invoked.
    
    Returns:
    The object returned by the method, which represents the result of invoking the method on the specified managed resource.
    
    Throws:
    MBeanException - Wraps one of the following Exceptions:
    
    An Exception thrown by the managed object's invoked method.
    
    ServiceNotFoundException: No ModelMBeanOperationInfo or no descriptor defined for the specified operation or the managed resource is null.
    
    InvalidTargetObjectTypeException: The 'targetType' field value is not 'objectReference'.
    ReflectionException - Wraps an Exception thrown while trying to invoke the method.
    
    RuntimeOperationsException - Wraps an IllegalArgumentException Method name is null.
  - getAttribute
```
public Object getAttribute(String attrName)
                    throws AttributeNotFoundException,
                           MBeanException,
                           ReflectionException
```
    Returns the value of a specific attribute defined for this ModelMBean. The last value returned by an attribute may be cached in the attribute's descriptor. The valid value will be in the 'value' field if there is one. If the 'currencyTimeLimit' field in the descriptor is:
    - <0 Then the value is not cached and is never valid. The getter method is invoked for the attribute. The 'value' and 'lastUpdatedTimeStamp' fields are cleared.
    - =0 Then the value is always cached and always valid. The 'value' field is returned. If there is no'value' field then the getter method is invoked for the attribute. The 'lastUpdatedTimeStamp' field and `value' fields are set to the attribute's value and the current time stamp.
    - >0 Represents the number of seconds that the 'value' field is valid. The 'value' field is no longer valid when 'lastUpdatedTimeStamp' + 'currencyTimeLimit' > Now.
      
      When 'value' is valid, 'value' is returned.
      
      When 'value' is no longer valid then the getter method is invoked for the attribute. The 'lastUpdatedTimeStamp' field and `value' fields are updated.
    Note: because of inconsistencies in previous versions of this specification, it is recommended not to use negative or zero values for currencyTimeLimit. To indicate that a cached value is never valid, omit the currencyTimeLimit field. To indicate that it is always valid, use a very large number for this field.
    
    If the 'getMethod' field contains the name of a valid operation descriptor, then the method described by the operation descriptor is executed. The response from the method is returned as the value of the attribute. If the operation fails or the returned value is not compatible with the declared type of the attribute, an exception will be thrown.
    
    If no 'getMethod' field is defined then the default value of the attribute is returned. If the returned value is not compatible with the declared type of the attribute, an exception will be thrown.
    
    The declared type of the attribute is the String returned by MBeanAttributeInfo.getType(). A value is compatible with this type if one of the following is true:
    - the value is null;
    - the declared name is a primitive type name (such as "int") and the value is an instance of the corresponding wrapper type (such as java.lang.Integer);
    - the name of the value's class is identical to the declared name;
    - the declared name can be loaded by the value's class loader and produces a class to which the value can be assigned.
    In this implementation, in every case where the getMethod needs to be called, because the method is invoked through the standard "invoke" method and thus needs operationInfo, an operation must be specified for that getMethod so that the invocation works correctly.
    Specified by:
    
    getAttribute in interface DynamicMBean
    
    Parameters:
    attrName - A String specifying the name of the attribute to be retrieved. It must match the name of a ModelMBeanAttributeInfo.
    
    Returns:
    The value of the retrieved attribute from the descriptor 'value' field or from the invocation of the operation in the 'getMethod' field of the descriptor.
    
    Throws:
    AttributeNotFoundException - The specified attribute is not accessible in the MBean. The following cases may result in an AttributeNotFoundException:
    
    No ModelMBeanInfo was found for the Model MBean.
    
    No ModelMBeanAttributeInfo was found for the specified attribute name.
    
    The ModelMBeanAttributeInfo isReadable method returns 'false'.
    MBeanException - Wraps one of the following Exceptions:
    
    InvalidAttributeValueException: A wrong value type was received from the attribute's getter method or no 'getMethod' field defined in the descriptor for the attribute and no default value exists.
    
    ServiceNotFoundException: No ModelMBeanOperationInfo defined for the attribute's getter method or no descriptor associated with the ModelMBeanOperationInfo or the managed resource is null.
    
    InvalidTargetObjectTypeException The 'targetType' field value is not 'objectReference'.
    
    An Exception thrown by the managed object's getter.
    ReflectionException - Wraps an Exception thrown while trying to invoke the getter.
    
    RuntimeOperationsException - Wraps an IllegalArgumentException: The attribute name in parameter is null.

    Specified by:
    
    getAttributes in interface DynamicMBean
    
    Parameters:
    attrNames - A String array of names of the attributes to be retrieved.
    
    Returns:
    The array of the retrieved attributes.
    
    Throws:

                         MBeanException,
                         ReflectionException
```
    Sets the value of a specific attribute of a named ModelMBean. If the 'setMethod' field of the attribute's descriptor contains the name of a valid operation descriptor, then the method described by the operation descriptor is executed. In this implementation, the operation descriptor must be specified correctly and assigned to the modelMBeanInfo so that the 'setMethod' works correctly. The response from the method is set as the value of the attribute in the descriptor.
    If currencyTimeLimit is > 0, then the new value for the attribute is cached in the attribute descriptor's 'value' field and the 'lastUpdatedTimeStamp' field is set to the current time stamp.
    If the persist field of the attribute's descriptor is not null then Persistence policy from the attribute descriptor is used to guide storing the attribute in a persistent store.
    Store the MBean if 'persistPolicy' field is:
    - != "never"
    - = "always"
    - = "onUpdate"
    - = "onTimer" and now > 'lastPersistTime' + 'persistPeriod'
    - = "NoMoreOftenThan" and now > 'lastPersistTime' + 'persistPeriod'
    Do not store the MBean if 'persistPolicy' field is:
    - = "never"
    - = "onTimer" && now < 'lastPersistTime' + 'persistPeriod'
    - = "onUnregister"
    - = "NoMoreOftenThan" and now < 'lastPersistTime' + 'persistPeriod'
    The ModelMBeanInfo of the Model MBean is stored in a file.
    Specified by:
    
    setAttribute in interface DynamicMBean
    
    Parameters:
    attribute - The Attribute instance containing the name of the attribute to be set and the value it is to be set to.
    
    Throws:
    AttributeNotFoundException - The specified attribute is not accessible in the MBean.
    The following cases may result in an AttributeNotFoundException:
    
    No ModelMBeanAttributeInfo is found for the specified attribute.
    
    The ModelMBeanAttributeInfo's isWritable method returns 'false'.
    InvalidAttributeValueException - No descriptor is defined for the specified attribute.
    MBeanException - Wraps one of the following Exceptions:
    
    An Exception thrown by the managed object's setter.
    
    A ServiceNotFoundException if a setMethod field is defined in the descriptor for the attribute and the managed resource is null; or if no setMethod field is defined and caching is not enabled for the attribute. Note that if there is no getMethod field either, then caching is automatically enabled.
    
    InvalidTargetObjectTypeException The 'targetType' field value is not 'objectReference'.
    
    An Exception thrown by the managed object's getter.
    ReflectionException - Wraps an Exception thrown while trying to invoke the setter.

                       throws Exception
```
    Allows the MBean to perform any operations it needs before being registered in the MBean server. If the name of the MBean is not specified, the MBean can provide a name for its registration. If any exception is raised, the MBean will not be registered in the MBean server.
    In order to ensure proper run-time semantics of RequireModelMBean, Any subclass of RequiredModelMBean overloading or overriding this method should call super.preRegister(server, name) in its own preRegister implementation.
    
    Specified by:
    
    preRegister in interface MBeanRegistration
    
    Parameters:
    server - The MBean server in which the MBean will be registered.
    name - The object name of the MBean. This name is null if the name parameter to one of the createMBean or registerMBean methods in the MBeanServer interface is null. In that case, this method must return a non-null ObjectName for the new MBean.
    
    Returns:
    The name under which the MBean is to be registered. This value must not be null. If the name parameter is not null, it will usually but not necessarily be the returned value.
    
    Throws:
    
    Exception - This exception will be caught by the MBean server and re-thrown as an MBeanRegistrationException.
  - postRegister
```
public void postRegister(Boolean registrationDone)
```
    Allows the MBean to perform any operations needed after having been registered in the MBean server or after the registration has failed.
    In order to ensure proper run-time semantics of RequireModelMBean, Any subclass of RequiredModelMBean overloading or overriding this method should call super.postRegister(registrationDone) in its own postRegister implementation.
    
    Specified by:
    
    postRegister in interface MBeanRegistration
    
    Parameters:
    registrationDone - Indicates whether or not the MBean has been successfully registered in the MBean server. The value false means that the registration phase has failed.

public void preDeregister()
                   throws Exception
```
    Allows the MBean to perform any operations it needs before being unregistered by the MBean server.
    In order to ensure proper run-time semantics of RequireModelMBean, Any subclass of RequiredModelMBean overloading or overriding this method should call super.preDeregister() in its own preDeregister implementation.
    
    Specified by:
    
    preDeregister in interface MBeanRegistration
    
    Throws:
    
    Exception - This exception will be caught by the MBean server and re-thrown as an MBeanRegistrationException.
  - postDeregister
```
public void postDeregister()
```
    Allows the MBean to perform any operations needed after having been unregistered in the MBean server.
    In order to ensure proper run-time semantics of RequireModelMBean, Any subclass of RequiredModelMBean overloading or overriding this method should call super.postDeregister() in its own postDeregister implementation.
