TypeObject [1] is a pattern in which an object uses another object as a class. ''The author of this page doesn't reveal what the [1] stands for, it may be "RalphJohnson and BobbyWoolf. "Type Object," PatternLanguagesOfProgramDesign 3, RobertMartin, DirkRiehle, and FrankBuschmann, eds., AddisonWesley, Reading, MA., 1997. ".'' ''I thought I'd WikiName all authors as a test, and - whoo! - see what I got!'' ---- AnswerMe: I've seen this mentioned as a pattern, particularly in ActiveObjectModel. Could someone write this up in pattern form, or at least give a little more detail? ---- I've seen this pattern mentioned in article about EclipseIde http://www.eclipse.org/articles/Article-Java-launch/launching-java.html An idea is understandable: some object describes a type of another object. But I agree that this page lacks detailed description of pattern. BTW, why this pattern cannot be found among categories on CategoryPattern page? ---- CategoryPattern
