Making dependencies visible - On the UML window menu, click on View – Visible Dependencies, then
check or uncheck the items on the list as appropriate. The only two categories of dependencies in the
example project are Inheritance and Other. Inheritance dependencies are indicated by black lines with
closed arrowheads that point from child to the parent to from an is-a relationship. Red dashed lines with
open arrowheads indicate other dependencies. These include the has-a relationship that indicates a
class includes one or more instances of another class. If a class references an instance variable or
method of another class, the red dashed arrow is drawn from the class where the reference is made to
the class where the referenced item is defined. In general, you probably want to make all dependencies
visible. as indicated in Figure 41.
Displaying the Legend - On the UML window menu, click on View – Legend, then set the desired
options. Typically, you will want the following options checked on: Show Legend, Visible Items Only, and
Small Font. Notice, the legend has been visible in the all of UML figures. Before the JDK classes were
excluded (Figure 39), they were included in the legend, but not after the Update. When you initially
generate your UML diagram, you may have to pan around it to locate the legend. Scaling the UML down
(e.g., dividing by 2) may help. Once you locate it, just select it, then drag to the location where you want it
as described in the next section.
