Library ClassThe access point for the JAR library is a class that extends the
Componentspackage com.cburch.gray; import java.util.Arrays; import java.util.List; import com.cburch.logisim.tools.AddTool; import com.cburch.logisim.tools.Library; import com.cburch.logisim.tools.Tool; /** The library of components that the user can access. */ public class Components extends Library { /** The list of all tools contained in this library.

This constructor is how * Logisim accesses first when it opens the JAR file: It looks for * a no-arguments constructor method of the user-designated class. */ public Components() { tools = Arrays.asList(new Tool[] { new AddTool(new GrayIncrementer()), new AddTool(new SimpleGrayCounter()), new AddTool(new GrayCounter()), }); } /** Returns the name of the library that the user will see. */ public String getDisplayName() { return "Gray Tools"; } /** Returns a list of all the tools available in this library. */ public List getTools() { return tools; } } Next: Simple Gray Counter. |
