Method Detail

luaStackCall

public boolean luaStackCall(LuaState vm)

Description copied from class: LFunction

Set up a Java invocation, and leave the results on the stack starting at base. The default implementation for LFunction delegates to the VM which provides convenience.

Overrides:

luaStackCall in class LFunction

luaSetEnv

public boolean luaSetEnv(LTable t)

Set the environment if a thread, or closure, and return 1, otherwise return 0

Overrides:

luaSetEnv in class LValue

luaGetEnv

public LTable luaGetEnv(LTable d)

Get the enviroment for this closure

Overrides:

luaGetEnv in class LValue

Parameters:

d - global environment to return if this is not a closure

isClosure

public boolean isClosure()

Returns true if this is a lua closure, false otherwise

Overrides:

isClosure in class LValue
