Array 数组

Array

CBrother数组是任何对象的有序整数索引集合，数组的索引从 0 开始，CBrother数组不需要指定大小，当向数组添加元素时，CBrother数组会自动增长。

例子:

function main(parm)
{
    var myarray = new Array(1,2);
    myarray.add("i'am string");
    var len = myarray.size();
    print "myarray size:" + len;
    print "myarray 0:" + myarray[0];
    print "myarray 1:" + myarray[1];
    print "myarray 2:" + myarray[2];
    myarray.remove(1);
    len = myarray.size();
    print "after remove. myarray size:" + len;
    print "myarray 0:" + myarray[0];
    print "myarray 1:" + myarray[1];    
    myarray.insert(0,55.55);
    myarray[1] = 100;
    len = myarray.size();
    print "after insert. myarray size:" + len;
    print "myarray 0:" + myarray[0];
    print "myarray 1:" + myarray[1];
    print "myarray 2:" + myarray[2];
    myarray.clear();
    len = myarray.size();
    print "after clear. myarray size:" + len;    
}

结果:

myarray size:3
myarray 0:1
myarray 1:2
myarray 2:i'am string
after remove. myarray size:2
myarray 0:1
myarray 1:i'am string
after insert. myarray size:3
myarray 0:55.55000
myarray 1:100
myarray 2:i'am string
after clear. myarray size:0

Array也可以只直接用[]来初始化:

function main(parm)
{
    var myarray = [1,2,"i'am string"];
    var len = myarray.size();
    print "myarray size:" + len;
    print "myarray 0:" + myarray[0];
    print "myarray 1:" + myarray[1];
    print "myarray 2:" + myarray[2];
}

结果:

myarray size:3
myarray 0:1
myarray 1:2
myarray 2:i'am string

foreach支持

foreach语句中的key表示元素在Array中的索引,value表示这个元素

function main(parm)
{
    var array = [1,2,3];
    print "foreach:";
    foreach(k,v : array)
    {
        print "k:" + k + ",v=" + v;
    }
    print "foreach_reverse:";
    foreach_reverse(k,v : array)
    {
        print "k:" + k + ",v=" + v;
    }
}

结果:

foreach:
k:0,v=1
k:1,v=2
k:2,v=3
foreach_reverse:
k:2,v=3
k:1,v=2
k:0,v=1
