/**
 * The state of one method invocation on a thread's call stack.
 * As a thread executes, stack frames are pushed and popped from
 * its call stack as methods are invoked and then return. A StackFrame
 * mirrors one such frame from a target VM at some point in its
 * thread's execution. The call stack is, then, simply a List of
 * StackFrame objects. The call stack can be obtained any time a thread
 * is suspended through a call to {@link ThreadReference#frames}
 * <p>
 * StackFrames provide access to a method's local variables and their
 * current values.
 * <p>
 * The lifetime of a StackFrame is very limited. It is available only
 * for suspended threads and becomes invalid once its thread is resumed.
 * <p>
 * Any method on <code>StackFrame</code> which
 * takes <code>StackFrame</code> as an parameter may throw
 * {@link VMDisconnectedException} if the target VM is
 * disconnected and the {@link VMDisconnectEvent} has been or is
 * available to be read from the {@link EventQueue}.
 * <p>
 * Any method on <code>StackFrame</code> which
 * takes <code>StackFrame</code> as an parameter may throw
 * {@link VMOutOfMemoryException} if the target VM has run out of memory.
