An And line is a dotted line that separates the orthogonal
components of an And state. There can be two or more orthogonal components
in a given And state and each behaves independently of the others.
If the system is in an And state, it is also simultaneously in a substate
of each orthogonal component.
About this task
The following figure shows an And line.
To draw
an And line to divide a state into substates:
Procedure
- Click the And line button
on Diagram Tools.
- Click in the middle of the upper edge of
the state to anchor the start of the And line.
- Move the cursor down to the bottom edge
of the state and click to anchor the end of the And line. IBM® Rational® Rhapsody® draws
a dotted line that divides the state into two halves (orthogonal states),
as shown in the following figure.
Results
The state label, which used to be inside
the state, has moved outside into a tab-like rectangle.
