Method Detail

register

public static void register(LuaState state)

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object

call

public int call(LuaCallFrame callFrame,
                int nArguments)

Description copied from interface: JavaFunction

General contract

Input:
callFrame = the frame that contains all the arguments, and where all the results should be put.
nArgs = number of function arguments
callFrame.get(i) = an argument (0 <= i < nArgs)

Specified by:

call in interface JavaFunction

Parameters:

callFrame - - the current callframe for the function

nArguments - - number of function arguments

Returns:

N - number of return values. The N top objects on the stack are considered the return values

pcall

public static int pcall(LuaCallFrame callFrame,
                        int nArguments)

luaAssert

public static void luaAssert(boolean b,
                             java.lang.String msg)

numberToString

public static java.lang.String numberToString(java.lang.Double num)

getArg

public static java.lang.Object getArg(LuaCallFrame callFrame,
                                      int n,
                                      java.lang.String type,
                                      java.lang.String function)

Parameters:

callFrame -

n -

type - must be "string" or "number" or one of the other built in types. Note that this parameter must be interned! It's not valid to call it with new String("number"). Use null if you don't care which type or expect more than one type for this argument.

function - name of the function that calls this. Only for pretty exceptions.

Returns:

variable with index n on the stack, returned as type "type".

getOptArg

public static java.lang.Object getOptArg(LuaCallFrame callFrame,
                                         int n,
