What does WWW.isDone mean?

Unity Engine
1

if WWW.isDone returns ture, does it mean that:
1.success without error?
2.WWW.assetbundle has been decompressed, or not until WWW.assetbundle is called?

It basically asks if the WWW object has completed it’s transfer.

In the documentation for WWW you have a basic usage. In that is a line:

yield www;

This line basically says, “Wait until www is done, then continue”

You can rewrite this as:

while(!www.isDone){
print("is Loading");
yield;
}

If any error occurs, does this continue?
