Examples of com.cburch.logisim.comp.ComponentFactory

com.cburch.logisim.comp.ComponentFactory
Represents a category of components that appear in a circuit. This class and Component share the same sort of relationship as the relation between classes and instances in Java. Normally, there is only one ComponentFactory created for any particular category.

        Circuit circ = null;


        ToolIcon(Tool tool) {
            this.tool = tool;
            if (tool instanceof AddTool) {
                ComponentFactory fact = ((AddTool) tool).getFactory(false);
                if (fact instanceof SubcircuitFactory) {
                    circ = ((SubcircuitFactory) fact).getSubcircuit();
                }
            }
        }
