public @interface Icons
```
Declare a set of icon files for the operator. The icons will be used by Streams Studio to show the operator in the graphical editor.
A 16x16 icon file location as well as a 32x32 icon location must be provided. The location of the icons is relative to the root directory of the toolkit containing the Java primitive operator.
For example, to specify an icon within the <Toolkit Directory>/icons folder, you would specify the following:
```
        @PrimitiveOperator
        @Icons(location16="icons/operator_icon16.gif" location32="icons/operator_icon32.gif")
        public class SomeOp extends AbstractOperator
 
```
