• getAttributetop

  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 The 'value' field is no longer valid when 'lastUpdatedTimeStamp' + 'currencyTimeLimit' 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    • When 'value' is no longer valid then the getter method is invoked for the attribute.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 javax.management.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.

  Parameters:

  @param attrName A String specifying the name of the attribute to be retrieved. It must match the name of a ModelMBeanAttributeInfo.

  Return:

  @return 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.

  Exceptions:

  @exception 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'.

  @exception MBeanException Wraps one of the following Exceptions:

  • javax.management.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.
  • javax.management.ServiceNotFoundException : No ModelMBeanOperationInfo defined for the attribute's getter method or no descriptor associated with the ModelMBeanOperationInfo or the managed resource is null.
  • javax.management.modelmbean.InvalidTargetObjectTypeException The 'targetType' field value is not 'objectReference'.
  • An Exception thrown by the managed object's getter.

  @exception ReflectionException Wraps an Exception thrown while trying to invoke the getter.

  @exception RuntimeOperationsException Wraps an IllegalArgumentException : The attribute name in parameter is null.

• invoketop

  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.

  Parameters:

  @param 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.

• setAttributetop

  public void setAttribute(Attribute attribute) throws AttributeNotFoundException, InvalidAttributeValueException, 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.

  Parameters:

  @param attribute The Attribute instance containing the name of the attribute to be set and the value it is to be set to.

  Exceptions:

  @exception 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'.

  @exception InvalidAttributeValueException No descriptor is defined for the specified attribute.

  @exception MBeanException Wraps one of the following Exceptions:

  • An Exception thrown by the managed object's setter.
  • A javax.management.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.
  • javax.management.modelmbean.InvalidTargetObjectTypeException The 'targetType' field value is not 'objectReference'.
  • An Exception thrown by the managed object's getter.

  @exception ReflectionException Wraps an Exception thrown while trying to invoke the setter.
