所有已实现的接口:

Serializable

public class LuaError
extends RuntimeException

RuntimeException that is thrown and caught in response to a lua error.

LuaError is used wherever a lua call to error() would be used within a script.

Since it is an unchecked exception inheriting from RuntimeException, Java method signatures do notdeclare this exception, althoug it can be thrown on almost any luaj Java operation. This is analagous to the fact that any lua script can throw a lua error at any time.

The LuaError may be constructed with a message object, in which case the message is the string representation of that object. getMessageObject will get the object supplied at construct time, or a LuaString containing the message of an object was not supplied.
