package com.sun.jdi;

/**
 * A proxy used by a debugger to examine or manipulate some entity
 * in another virtual machine. Mirror is the root of the
 * interface hierarchy for this package. Mirrors can be proxies for objects
 * in the target VM ({@link ObjectReference}), primitive values
 * (for example, {@link IntegerValue}), types (for example,
 * {@link ReferenceType}), dynamic application state (for example,
 * {@link StackFrame}), and even debugger-specific constructs (for example,
 * {@link com.sun.jdi.request.BreakpointRequest}).
 * The {@link VirtualMachine} itself is also
 * considered a mirror, representing the composite state of the
 * target VM.
 * <P>
 * There is no guarantee that a particular entity in the target VM will map
 * to a single instance of Mirror. Implementors are free to decide
 * whether a single mirror will be used for some or all mirrors. Clients
 * of this interface should always use <code>equals</code> to compare
 * two mirrors for equality.
 * <p>
 * Any method on a {@link com.sun.jdi.Mirror} that takes a <code>Mirror</code> as an
 * parameter directly or indirectly (e.g., as a element in a <code>List</code>) will
 * throw {@link com.sun.jdi.VMMismatchException} if the mirrors are from different
 * virtual machines.
