converting qx.core.Object to map

Rate this Message:
Hi, what is the best way of converting a qx.core.Object instance into a map containing its properties' keys and values? Of course, one can easily do var json = qx.util.Serializer.toJson( myQxCoreObjectInstance ); var map = qx.util.Json.parse( json ); but that appears to be wasteful. I wonder if a toMap() method would be a good addition to the qx.core.Object class.

Derrell,
I just had to try the Playground code for the first time, and that's really neat! But, doesn't your code just provide a list of the properties names for a given class, rather than the properties and values of an instance of a class? I think that's what he was looking to get in the map output. You know, like: allowShrinkY:true allowShrinkX:false etc. Gene On Tue, 2009-10-27 at 22:44 -0400, Derrell Lipman wrote: On Tue, Oct 27, 2009 at 18:43, panyasan <info@...> wrote: ------------------------------------------------------------------------------ Come build with us!

Take a look at the "map" variable in Darrell's example.

Well I am enumerating the values of the properties, but you're right that what I've done may not be what Christian is looking for. Since these functions take a class as parameter rather than an instance, they can't possibly provide a particular instance's property values. Maybe the inside of the loop should contain calls akin to this: var propGet = "myObjectInstance.get" + upperFirstChar(list[i]) + "()"; map[list[i]] = eval(propGet); There is a method someplace that converts the first character to upper case, what the above upperFirstChar() does. I think it's used in qx/Class.js or qx/core/Property.js, but since I don't have the qooxdoo source in front of me, I can't currently provide details.

eval is evil! Also it won't work for grouped properties.
