Question about FilterFunction of ArrayCollection

Question

Hi,

I want to filter ArrayCollection based on multiple values ( or array ). For example, My sample array "myArray" has four values; Active, Close,Returned and Submitted.

My code looks like,

sampleData.filterFunction =doStatusFilter
sampleData.refresh();

public function doStatusFilter(item:Object):Boolean {  
    var i:int;   
    var query:String;
    var sep:String
    query="(";
    sep=""

    for (i=0; i<myArray.length; i++) {        
           query=query+sep+(item.status + "=='"+ myArray[i]+"'");
       sep=" || ";
    }  
    query=query+")";

    //Here is my problem..Since return type is boolean
return query 
  }

I can build query successfully but how do I execute "query" ?

I need to filter my collection based on multiple status.

Updates:: Here is solution ....

package com.rish
{
public class FilterSelector
{
    import mx.controls.*;
    private var _filterField:String;
    private var _filterTypes:Array;

    public function FilterSelector(){ /**/ }

    public function get filterField():String
    {
        return _filterField;
    }

    public function set filterField(value:String):void
    {
        _filterField = value;
    }

    public function addFilterTypes(params:Array):void
    {
        _filterTypes = params;

    }

    public function generateFilterFunction():Function
    {
        var f:Function = function(item:Object):Boolean
                        { 
                            for each(var type:String in _filterTypes)
                            {
                                if(item[filterField] == type) return true;
                            }
                            return false;
                        };
        return f;
    }
}
}

fs = new FilterSelector();
fs.filterField = "status";
fs.addFilterTypes(apStatusArray);
sampleData.filterFunction =fs.generateFilterFunction();
sampleData.refresh();
