Examples of ThreeArgFunction

org.luaj.vm2.lib.ThreeArgFunction

Abstract base class for Java function implementations that take two arguments and return one value.

Subclasses need only implement {@link LuaValue#call(LuaValue,LuaValue,LuaValue)} to complete this class, simplifying development. All other uses of {@link #call()}, {@link #invoke(Varargs)},etc, are routed through this method by this class, dropping or extending arguments with {@code nil} values as required.

If more or less than three arguments are required, or variable argument or variable return values, then use one of the related function {@link ZeroArgFunction}, {@link OneArgFunction}, {@link TwoArgFunction}, or {@link VarArgFunction}.

See {@link LibFunction} for more information on implementation libraries and library functions. @see #call(LuaValue,LuaValue,LuaValue) @see LibFunction @see ZeroArgFunction @see OneArgFunction @see TwoArgFunction @see VarArgFunction
