Map

CBrother字典是类似 "key" => "value" 这样的键值对集合，key可以是任意对象。字典的元素没有特定的顺序，如果顺序很重要的话就要使用数组了。

例子:

function main(parm)
{
	var myMap = new Map();
	myMap.add("tony","age 18");
	myMap.add("jim","age 19");
	myMap.add("lily","age 17");
	
	var len = myMap.size();
	print "myMap size:" + len;
	
	print "tony:" + myMap.get("tony");
	print "jim:" + myMap.get("jim");
	print "lily:" + myMap.get("lily");
	
	myMap.remove("jim");
	myMap.set("tony","age 17");
	
	len = myMap.size();
	print "after remove. myMap size:" + len;
	
	print "tony:" + myMap.get("tony");
	print "lily:" + myMap.get("lily");	
	
	myMap.clear();
	len = myMap.size();
	print "after clear. myMap size:" + len;	
}

结果:

myMap size:3
tony:age 18
jim:age 19
lily:age 17
after remove. myMap size:2
tony:age 17
lily:age 17
after clear. myMap size:0

Map也可以用{}来初始化:

function main(parm)
{
	var myMap = {"tony":"age 18","jim":"age 19"};
	myMap["lily"] = "age 17";
	
	var len = myMap.size();
	print "myMap size:" + len;
	
	print "tony:" + myMap.get("tony");
	print "jim:" + myMap.get("jim");
	print "lily:" + myMap.get("lily");
}

结果:

myMap size:3
tony:age 18
jim:age 19
lily:age 17

foreach支持

function main(parm)
{
	var myMap = {"tony":"age 18","jim":"age 19","lily":"age 17"};
	
	foreach(k,v : map)
	{
		print k + ":" + v;
	}
	
	print "========================";
	
	foreach(k,v : map)
	{
		if(key == "lily")
		{
			foreach_del;
			continue;
		}
		print k + ":" + v;
	}
}

结果:

jim:age 19
lily:age 17
tony:age 18
========================
jim:age 19
tony:age 18
