- The value of the attribute retrieved.
- Throws:
AttributeNotFoundException
- if specified attribute does not exist or cannot be retrievedMBeanException
- Wraps ajava.lang.Exception
thrown by the MBean's getter.ReflectionException
- Wraps ajava.lang.Exception
thrown while trying to invoke the getter.- See Also:
-
setAttribute
void setAttribute(Attribute attribute) throws AttributeNotFoundException, InvalidAttributeValueException, MBeanException, ReflectionException Set the value of a specific attribute of the Dynamic MBean.- Parameters:
attribute
- The identification of the attribute to be set and the value it is to be set to.- Throws:

- if value specified is not valid for the attributeMBeanException
- Wraps ajava.lang.Exception
thrown by the MBean's setter.ReflectionException
- Wraps ajava.lang.Exception
thrown while trying to invoke the MBean's setter.- See Also:
