Please complete this checklist (turn [ ] into [X]) before you submit:
|
||||
|
||||
- [ ] I completed the above Submission Info
|
||||
- [ ] I built the project in IntelliJ (Build > Build Project)
|
||||
- [ ] I implemented the ClassHierarchyBuilder
|
||||
- [ ] I implemented the CallGraphBuilder
|
||||
- [ ] I implemented the CallGraphRenderer
|
||||
- [ ] I wrote the source code myself and did not look at the source code of my class mates
|
||||
- [ ] I manually checked that my implementation is correct by doing this:
|
||||
- [ ] I studied the source code within test-input/pacman-src.jar
|
||||
- [ ] I ran App to produce the dot file (in test-output/)
|
||||
- [ ] I ran dot to turn the dot file in test-output into a PDF
|
||||
- [ ] I manually verified that the PDF contains the correct call graph
|
||||
- [ ] I committed my changes (at least one commit, but possibly many)
|
||||
- [ ] I pushed my commits to GitHub
