In the Data Services tab of Flash Builder 4 (I'm using the plugin for Eclipse), I see my available services and their methods. The services are displayed with what looks like three little grey gears. What do the symbols next to the methods mean? I see green triangles, blue triangles, a group of three smaller blue triangles, a grey sphere and a blue triangle with a little blank page at one corner. Where can I go to find out what all these icons mean?
