Represents a management bean that provides a
dynamic interface. Users of a
DynamicMBean
may retrieve information about its attributes at
runtime and use this information to dynamically
obtain the corresponding values of these attributes.
getAttribute
public Object getAttribute(String name)
throws AttributeNotFoundException,
MBeanException,
ReflectionException Obtains the value of the specified attribute of the
management bean. The management bean should perform
a lookup for the named attribute, and return its value
by calling the appropriate getter method, if possible.
name - the name of the attribute to retrieve.
- the value of the specified attribute.
AttributeNotFoundException - if the name does not
correspond to an attribute
of the bean.MBeanException - if retrieving the attribute causes
the bean to throw an exception (which
becomes the cause of this exception).ReflectionException - if an exception occurred in trying
to use the reflection interface
to lookup the attribute. The
thrown exception is the cause of
this exception.
getAttributes
public AttributeList getAttributes(String[] names)
Obtains the values of each of the specified attributes
of the management bean. The returned list includes
those attributes that were retrieved and their
corresponding values.
names - the names of the attributes to retrieve.
- a list of the retrieved attributes.
getMBeanInfo
public MBeanInfo getMBeanInfo()
Returns an information object which lists the attributes
and actions associated with the management bean.
- a description of the management bean, including
all exposed attributes and actions.
invoke
public Object invoke(String name,
Object[] params,
String[] signature)
throws MBeanException,
ReflectionException Invokes the specified action on the management bean using
the supplied parameters. The signature of the action is
specified by a
String array, which lists the classes
corresponding to each parameter. The class loader used to
load these classes is the same as that used for loading the
management bean itself.
name - the name of the action to invoke.params - the parameters used to call the action.signature - the signature of the action.
- the return value of the action.
MBeanException - if the action throws an exception. The
thrown exception is the cause of this
exception.ReflectionException - if an exception occurred in trying
to use the reflection interface
to invoke the action. The
thrown exception is the cause of
this exception.
setAttributes
public AttributeList setAttributes(AttributeList attributes)
Sets the value of each of the specified attributes
to that supplied by the
Attribute object.
The returned list contains the attributes that were
set and their new values.
attributes - the attributes to set.
- a list of the changed attributes.
