Hi developers *and* users, shall we try to come up with a good Exception design for master?
Currently, the CDK uses a mix of various CDK specific exceptions, though we officially promote the single use of CDKException. Others have requested to use more general exceptions, like IllegalArgumentException. Today, another user problem came up, a NPE upon missing 2D coordinates in the renderer, where in fact a IllegalArgumentException may be appropriate, with a good error message. I like to discuss this issue, and in particular these three designs: 1. Only CDKException with proper messages (current formal design of the CDK, which several classes violate) 2. Use CDK-specific, tuned exceptions, such as NoSuchAtomTypeException (existing already) and Missing2DCoordinatesException 3. Use Java Exceptions only, like IllegalArgumentException with proper messages There are pros and cons for all of them. Let's try to get them clear first. Egon -- Dr E.L.
