Solutions to these exercises are supplied in Section B.2.1
Figure 6-30 shows a sequence diagram, and Figure 6-31 shows a collaboration diagram. These figures are equivalent; that is, they have the same elements. Identify the missing communications and guard expression and describe the interaction and collaboration. The missing communications in Figure 6-30 are labeled
ELM-01andELM-02. The missing guard expression in Figure 6-30 is labeledELM-03. The missing communications in Figure 6-31 are labeledELM-04,ELM-05, andELM-06.Describe Figures Figure 6-32 and Figure 6-33: identify the various elements. These elements are used for generating a report and its sections.
Update the diagrams stepwise to show the following interaction and collaboration. After each step, check your answers against the solutions shown in Appendix B:
For each section, the
Reportelement retrieves the section’s data using theOutputData := GetData ( )communication sent to theSectionelement, and formats the data using theOutputData := FormatData (OutputData)communication sent to itself.If the section’s data is not summary data, the
Reportelement simply outputs the data to theOutputPrinterInterfaceelement using theOutputNonSummaryData(OutputData)communication sent to theOutputPrinterInterfaceelement.If the section’s data is summary data, the
Reportelement simply outputs the data to theOutputPrinterInterfaceelement using theOutputSummaryData(OutputData)communication sent to theOutputPrinterInterfaceelement.
