ActionScript 3.0 :: Comparing Objects Binary Representation?

I have some objects that are very, very likely to be equal. I'm comparing them every second to check if they're the same as one stored in a data model on the client.Instead of having to check 5-6 data points to make sure they're equal, I would like to compare the binary to tell if they're not equal, so I can quickly overwrite the object in the collection if they do not have an identical binary representation.for example, I have the following objects:

ActionScript Code:
class tag{
var xCoord;

[code]....

So, instead of doing this sort of comparison for every member in the class

ActionScript Code:
if ( tagOne.xCoord != tagTwo.xCoord ){
swapTagsInCollection (tagOne, tagTwo);
}

I would like to do something like this.

ActionScript Code:
if ( tagOneBinary != tagTwoBinary ){
swapTagsInCollection (tagOne, tagTwo);
}
