Compare two objects

07.11.07 | Comment?

If you ever wondered how can you compare 2 objects (big structure objects that can not be compared by Flex itself using the === operator) in Flex to find out if they are identically the same one of the methods used were to check all their attributes.

Another much better and faster method is this:

public function compareObject(obj1:Object,obj2:Object):Boolean
{
    var buffer1:ByteArray = new ByteArray();
    buffer1.writeObject(obj1);
    var buffer2:ByteArray = new ByteArray();
    buffer2.writeObject(obj2);
 
    // compare the lengths
    var size:uint = buffer1.length;
    if (buffer1.length == buffer2.length) {
        buffer1.position = 0;
        buffer2.position = 0;
 
        // then the bits
        while (buffer1.position < size) {
            var v1:int = buffer1.readByte();
            if (v1 != buffer2.readByte()) {
                return false;
            }
        }    
        return true;                        
    }
    return false;
}
