getStackTrace()方法介绍

/** * Returns an array of stack trace elements representing the stack dump * of this thread. This method will return a zero-length array if * this thread has not started, has started but has not yet been * scheduled to run by the system, or has terminated. * If the returned array is of non-zero length then the first element of * the array represents the top of the stack, which is the most recent * method invocation in the sequence. The last element of the array * represents the bottom of the stack, which is the least recent method * invocation in the sequence. * * <p>If there is a security manager, and this thread is not * the current thread, then the security manager's * <tt>checkPermission</tt> method is called with a * <tt>RuntimePermission("getStackTrace")</tt> permission * to see if it's ok to get the stack trace. * * <p>Some virtual machines may, under some circumstances, omit one * or more stack frames from the stack trace. In the extreme case, * a virtual machine that has no stack trace information concerning * this thread is permitted to return a zero-length array from this * method. * * @return an array of <tt>StackTraceElement</tt>, * each represents one stack frame. * * @throws SecurityException * if a security manager exists and its * <tt>checkPermission</tt> method doesn't allow * getting the stack trace of thread. * @see SecurityManager#checkPermission * @see RuntimePermission * @see Throwable#getStackTrace * * @since 1.5 */
