Flex小工具: 匹配String

需求

分别有两列数据, A列作为数据源, B列中数据都来自于A列. 现在需要验证B列中的数据是否都能在A列中匹配到相同的数据.

核心代码:

var sourceArray:Array = strSource.split("\n"); // Get array from String;

			/**
			 * Convert array to Map, array value as the key, and the total nuber of the same value in the array as the value.
			 */
			private static function convertArrayToMap(array:Array):Object {
				var map:Object = new Object();
				
				for each (var str:String in array) 
				{
					var value:int = map[str] == null ? 0 : map[str];
					if(value < 1) {
						map[str] = 1; // init count;
					}else {
						map[str] = value + 1; // Add one
					}
				}
				
				return map;
			}
