The Java virtual machine to which it is - * attached is sometimes called the <i>target virtual machine</i>, or <i>target VM</i>. - * An application (typically a tool such as a managemet console or profiler) uses a - * VirtualMachine to load an agent into the target VM. For example, a profiler tool - * written in the Java Language might attach to a running application and load its - * profiler agent to profile the running application. </p> - * <p/> - * <p> A VirtualMachine is obtained by invoking the {@link #attach(String) attach} method - * with an identifier that identifies the target virtual machine. The identifier is - * implementation-dependent but is typically the process identifier (or pid) in - * environments where each Java virtual machine runs in its own operating system process. - * Alternatively, a <code>VirtualMachine</code> instance is obtained by invoking the - * {@link #attach(VirtualMachineDescriptor) attach} method with a {@link - * com.sun.tools.attach.VirtualMachineDescriptor VirtualMachineDescriptor} obtained - * from the list of virtual machine descriptors returned by the {@link #list list} method. - * Once a reference to a virtual machine is obtained, the {@link #loadAgent loadAgent}, - * {@link #loadAgentLibrary loadAgentLibrary}, and {@link #loadAgentPath loadAgentPath} - * methods are used to load agents into target virtual machine. The {@link - * #loadAgent loadAgent} method is used to load agents that are written in the Java - * Language and deployed in a {@link java.util.jar.JarFile JAR file}. (See - * {@link java.lang.instrument} for a detailed description on how these agents - * are loaded and started). The {@link #loadAgentLibrary loadAgentLibrary} and - * {@link #loadAgentPath loadAgentPath} methods are used to load agents that - * are deployed in a dynamic library and make use of the <a - * href="../../../../../../../../technotes/guides/jvmti/index.html">JVM Tools - * Interface</a>. </p> - * <p/> - * <p> In addition to loading agents a VirtualMachine provides read access to the - * {@link java.lang.System#getProperties() system properties} in the target VM. - * This can be useful in some environments where properties such as - * <code>java.home</code>, <code>os.name</code>, or <code>os.arch</code> are - * used to construct the path to agent that will be loaded into the target VM. - * <p/> - * <p> The following example demonstrates how VirtualMachine may be used:</p> - * <p/> - * <pre> - * <p/> - * // attach to target VM - * VirtualMachine vm = VirtualMachine.attach("2177"); - * <p/> - * // get system properties in target VM - * Properties props = vm.getSystemProperties(); - * <p/> - * // construct path to management agent - * String home = props.getProperty("java.home"); - * String agent = home + File.separator + "lib" + File.separator - * + "management-agent.jar"; - * <p/> - * // load agent into target VM - * vm.loadAgent(agent, "com.sun.management.jmxremote.port=5000"); - * <p/> - * // detach - * vm.detach(); - * <p/> - * </pre> - * <p/> - * <p> In this example we attach to a Java virtual machine that is identified by - * the process identifier <code>2177</code>. The system properties from the target - * VM are then used to construct the path to a <i>management agent</i> which is then - * loaded into the target VM.

-/**
- * Attach provider class for attaching to a Java virtual machine.
- * <p/>
- * <p> An attach provider is a concrete subclass of this class that has a
- * zero-argument constructor and implements the abstract methods specified
- * below. </p>
- * <p/>
- * <p> An attach provider implementation is typically tied to a Java virtual
- * machine implementation, version, or even mode of operation. That is, a specific
- * provider implementation will typically only be capable of attaching to
- * a specific Java virtual machine implementation or version. For example, Sun's
- * JDK implementation ships with provider implementations that can only attach to
- * Sun's <i>HotSpot</i> virtual machine. In general, if an environment
- * consists of Java virtual machines of different versions and from different
- * vendors then there will be an attach provider implementation for each
- * <i>family</i> of implementations or versions. </p>
- * <p/>
- * <p> An attach provider is identified by its {@link #name <i>name</i>} and
- * {@link #type <i>type</i>}. The <i>name</i> is typically, but not required to
- * be, a name that corresponds to the VM vendor. The Sun JDK implementation,
- * for example, ships with attach providers that use the name <i>"sun"</i>. The
- * <i>type</i> typically corresponds to the attach mechanism. For example, an
- * implementation that uses the Doors inter-process communication mechanism
- * might use the type <i>"doors"</i>. The purpose of the name and type is to
- * identify providers in environments where there are multiple providers
- * installed. </p>
- * <p/>
- * <p> AttachProvider implementations are loaded and instantiated at the first
- * invocation of the {@link #providers() providers} method. This method
- * attempts to load all provider implementations that are installed on the
- * platform. </p>
- * <p/>
- * <p> All of the methods in this class are safe for use by multiple
- * concurrent threads. </p>
