All Implemented Interfaces:

java.io.Serializable

public class LuaError
extends java.lang.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.
