Introduction
AssetFilter is an optional utility class in Gaia. It is not compiled as part of the framework, so you need to import it when you want to use it.

com.gaiaframework.utils.AssetFilter

Inside the utils package is a static class called AssetFilter. AssetFilter allows you to filter out the assets you need from a Page assets object. It has five public static methods, all of which take a single assets object as an argument, and returns an object with just those assets, stored by their id, just like in the original assets object.

This class is useful if you have mixed types of Assets on a Page and you want to iterate through one type for some purpose.

Usage Example
On the timeline of a Page Flash file:

import com.gaiaframework.utils.AssetFilter; var onlySounds:Object = AssetFilter.getSound(assets); var onlyImages:Object = AssetFilter.getImage(assets);
