方法详细资料

call

public LuaValue call(LuaValue x,
                     LuaValue y)

从类复制的说明: LuaValue

Call this with 2 arguments, including metatag processing, and return only the first return value.

If this is a LuaFunction, call it, and return only its first return value, dropping any others. Otherwise, look for the LuaValue.CALL metatag and call that.

If the return value is a Varargs, only the 1st value will be returned. To get multiple values, use LuaValue.invoke() instead.

To call this as a method call, use LuaValue.method(LuaValue) instead.

指定者:

call 在类中 TwoArgFunction

参数:

x - First argument to supply to the called function

y - Second argument to supply to the called function

返回:

First return value (this(arg1,arg2)), or LuaValue.NIL if there were none.

另请参阅:

LuaValue.call(), LuaValue.call(LuaValue), LuaValue.call(LuaValue, LuaValue, LuaValue), LuaValue.invoke(LuaValue, Varargs), LuaValue.method(String,LuaValue,LuaValue), LuaValue.method(LuaValue,LuaValue,LuaValue)

call

protected abstract double call(double x,
                               double y)
