for i, value in ipairs(myArray) do print("索引:", i, "值:", value) end ``` 在这个例子中,我们定义了一个名为myArray的数组,然后使用for-in语法遍历该数组。在循环体代码中,我们使用了ipairs函数来迭代数组的元素,将每个元素的索引赋值给变量i,将元素的值赋值给变量value,并将它们打印出来。 通过fo...

考虑主线程正在对Lua table中的Array部分做复制操作:foreach i do A[i] = A[i+1] end,这时候GC算法可能也扫描到了该对象,就会发生如下的情况。 如上图所示,GC算法处理A[i]节点之后,主线程可能完成了两条指令A[i]=A[i+1], A[i+1]=A[i+2],这样GC算法读取到的A[i]是A[i]=A[i+1]执行之前...

Luaj in interpreted mode performs well for the benchmarks, and even better when the lua-to-java-bytecode (luajc) compiler is used, and actually executes faster than C-based lua in some cases. It is also faster than Java-lua implementations Jill, Kahlua, and Mochalua for all benchmarks...
