* A platform MXBean is a <i>managed bean</i> that conforms to

* a set of basic data types described below.
* See <a href="../../../javax/management/MXBean.html#MXBean-spec">
* the specification of MXBeans</a> for details.
* All platform MXBean interfaces extend {@link PlatformManagedObject}s
* and new methods may be added in these interfaces

* <p>
* A JMX management application and the platform <tt>MBeanServer</tt>
* can interoperate without requiring classes for MXBean specific
* data types.
* The data types being transmitted between the JMX connector
* server and the connector client are
* {@linkplain javax.management.openmbean.OpenType open types}
* and this allows interoperation across versions.
* <p>
* The platform MXBean interfaces use only the following data types:
* <ul>
* <li>Primitive types such as <tt>int</tt>, <tt>long</tt>,
* <tt>boolean</tt>, etc</li>
* <li>Wrapper classes for primitive types such as
* {@link java.lang.Integer Integer}, {@link java.lang.Long Long},
* {@link java.lang.Boolean Boolean}, etc and
* {@link java.lang.String String}</li>
* <li>{@link java.lang.Enum Enum} classes</li>
* <li>Classes that define only getter methods and define a static
* <tt>from</tt> method with a
* {@link javax.management.openmbean.CompositeData CompositeData}
* argument to convert from an input <tt>CompositeData</tt> to

* a primitive type, a wrapper class,
* an enum class, or a class supporting conversion from a
* <tt>CompositeData</tt> to its class
* </li>
* </ul>
*
* <p>
* When an attribute or operation of a platform MXBean
* is accessed via an <tt>MBeanServer</tt>, the data types are mapped
* as follows:
* <ul>
* <li>A primitive type or a wrapper class is mapped
* to the same type.
* </li>
* <li>An {@link Enum} is mapped to
* <tt>String</tt> whose value is the name of the enum constant.
* <li>A class that defines only getter methods and a static
* <tt>from</tt> method with a
* {@link javax.management.openmbean.CompositeData CompositeData}
* argument is mapped to
* {@link javax.management.openmbean.CompositeData CompositeData}.
* </li>
* <li><tt>Map&lt;K,V&gt;</tt> is mapped to
* {@link javax.management.openmbean.TabularData TabularData}
* whose row type is a
* {@link javax.management.openmbean.CompositeType CompositeType} with
* two items whose names are <i>"key"</i> and <i>"value"</i>
* and the item types are
* the corresponding mapped type of <tt>K</tt> and <tt>V</tt>
* respectively and the <i>"key"</i> is the index.
* </li>
* <li><tt>List&lt;E&gt;</tt> is mapped to an array with the mapped
* type of <tt>E</tt> as the element type.
* </li>
* <li>An array of element type <tt>E</tt> is mapped to
* an array of the same dimenions with the mapped type of <tt>E</tt>
* as the element type.</li>
* </ul>
*
* The {@link javax.management.MBeanInfo MBeanInfo}
* for a platform MXBean
* describes the data types of the attributes and operations
* as primitive or open types mapped as specified above.
*
* <p>
* For example, the {@link MemoryMXBean}
* interface has the following <i>getter</i> and <i>setter</i> methods:
*
* <blockquote><pre>
* public MemoryUsage getHeapMemoryUsage();
* public boolean isVerbose();
* public void setVerbose(boolean value);
* </pre></blockquote>
*
* These attributes in the <tt>MBeanInfo</tt>
* of the <tt>MemoryMXBean</tt> have the following names and types:
*
* <blockquote>
* <table border>
* <tr>
* <th>Attribute Name</th>
* <th>Type</th>
* </tr>
* <tr>
* <td><tt>HeapMemoryUsage</tt></td>
* <td>{@link MemoryUsage#from
* CompositeData representing MemoryUsage}</td>
* </tr>
* <tr>
* <td><tt>Verbose</tt></td>
* <td><tt>boolean</tt></td>
* </tr>
* </table>
* </blockquote>

* <h4><a name="MXBeanNames">MXBean Names</a></h4>
* Each platform MXBean for a Java virtual machine has a unique
* {@link javax.management.ObjectName ObjectName} for
* registration in the platform <tt>MBeanServer</tt> that can
* be obtained by calling the {@link PlatformManagedObject#getObjectName}
* method.
*
* <p>
* The {@link #getPlatformManagementInterfaces getPlatformManagementInterfaces}

* including the standard management interfaces listed in the tables
* below as well as the management interfaces extended by the JDK implementation.

There are three different ways to access the management interfaces.
<p>An application can monitor the instrumentation of the
Java virtual machine and the runtime in the following ways:
<p>
<ol>
<li>Call the methods in the MXBean directly within the same
Java virtual machine.
<blockquote><pre>
<b>1. Direct access to an MXBean interface</b>
<p>
<ul>
<li>Get an MXBean instance locally in the running Java virtual machine:<p>
<pre>
RuntimeMXBean mxbean = ManagementFactory.getRuntimeMXBean();
// Get the standard attribute "VmVendor"
String vendor = mxbean.getVmVendor();
</pre>
</blockquote>
</li>
<p>Or by calling the
{@link java.lang.management.ManagementFactory#getPlatformMXBean(Class)
getPlatformMXBean} or
{@link java.lang.management.ManagementFactory#getPlatformMXBeans(Class)
getPlatformMXBeans} method:
<pre>
RuntimeMXBean mxbean = ManagementFactory.getPlatformMXBean(RuntimeMXBean.class);
<li>Go through a <tt>MBeanServerConnection</tt> connecting
to the <tt>platform MBeanServer</tt> of a running virtual machine.</li>
<blockquote><pre>
// Get the standard attribute "VmVendor"
String vendor = mxbean.getVmVendor();
</pre>
<p>
</li>
<li>Construct an MXBean proxy instance that forwards the
method calls to a given MBeanServer:<p>
<pre>
MBeanServerConnection mbs;
// Connect to a running JVM (or itself) and get MBeanServerConnection

</pre>
<p>A proxy is typically used to access an MXBean
in a remote Java virtual machine.
An alternative way to create an MXBean proxy is:
