Defect

• also find as dependency a class inside an annotation. This is likely a String, still could find it @IdClass(ChangeHistoryDetailPK.class) class …

Tools

• find boundaries of my own code, i.e. find leafs of my dependency hull
  • find all without dependency on my code
  • find all with one dependency to these
  • etc.

Classpath (JavaClass::Classpath)

• WARs and EARs contain JARs and a folder

Class File Format (JavaClass::ClassFile)

• understand synthetic class
• implement byte code awareness
  • add the byte code sequences to the methods so it can be analysed later (see JVM spec)
  • scanning of byte code for numbers, which methods loaded, which fields loaded
• see what similar project by unageanu has to offer ;-)

Class Analysis, on a single class (JavaClass::ClassScanner)

• count outgoing references (usage) per method, similar to general imported types
• display graph of fields and methods per class and which methods use/call which (as seen in "Code Blindness")

Metrics/Analysis across a whole classpath (JavaClass::Analyse)

• add collecting of incoming references (mark my interfaces, mark my referenced classes)
  • can calculate stability
  • find interfaces with only 1 implementation (smell?)
• "Greed Detector" = "metric" if all referencing classes of a class is another package, propose moving it there.
  • count outgoing references (usage) per method
  • which signatures are called how often
  • maybe move current method there?
• Chidamber and Kemerer Java Metrics (ckjm)
• The CRSS Metric for Package Design Quality
• Evolutionary architecture and emergent design: Emergent design through metrics

Test

• test with a large set of classes
  • use all classes of all JDKs against javap (compileTheWorld)
  • use the Quality Corpus
• improve test coverage
