CRC Cards

CRC Cards: a tool for object-oriented design

CRC cards are a tool to help you think through object-oriented designs.

This is a CRC card simulator made with Decker.

For each important class in your system, you create a card with a class name, its responsibilities, and its collaborators (names of other classes that work with it). 

To use this tool in decker, press the + button to spawn a new CRC card.

If you like,  you can make a copy of the crc tool in decker for each project or version of your system, using the following menu commands:

•  Card -> Copy
•  File -> New Card
•  Edit->Paste Card

The CRC cards are draggable within the decker card, and you can just click on  click any of its fields to edit.

To bring a CRC card to the front or delete it, use the widgets tool in decker.

You can also use the widgets tool to  hide or delete this help text.
