InvocationHandler that forwards methods in an MBean's
management interface through the MBean server to the MBean.
Given an MBeanServerConnection , the ObjectName
of an MBean within that MBean server, and a Java interface
Intf that describes the management interface of the
MBean using the patterns for a Standard MBean or an MXBean, this
class can be used to construct a proxy for the MBean. The proxy
implements the interface Intf such that all of its
methods are forwarded through the MBean server to the MBean.
If the InvocationHandler is for an MXBean, then the parameters of
a method are converted from the type declared in the MXBean
interface into the corresponding mapped type, and the return value
is converted from the mapped type into the declared type. For
example, with the method
public List reverse(List list);
and given that the mapped type for List is String[] , a call to proxy.reverse(someList) will convert
someList from a List to a String[] ,
call the MBean operation reverse , then convert the returned
String[] into a List .
The method Object.toString(), Object.hashCode(), or
Object.equals(Object), when invoked on a proxy using this
invocation handler, is forwarded to the MBean server as a method on
the proxied MBean only if it appears in one of the proxy's
interfaces. For a proxy created with JMX.newMBeanProxy or JMX.newMXBeanProxy , this means that the method must appear in the
Standard MBean or MXBean interface. Otherwise these methods have
the following behavior:
toString() returns a string representation of the proxy
hashCode() returns a hash code for the proxy such
that two equal proxies have the same hash code
equals(Object)
returns true if and only if the Object argument is of the same
proxy class as this proxy, with an MBeanServerInvocationHandler
that has the same MBeanServerConnection and ObjectName; if one
of the MBeanServerInvocationHandler s was constructed with
a Class argument then the other must have been constructed
with the same Class for equals to return true.
