edu.umd.cs.findbugs.ba.XField

Packages that use XField

Package	Description
edu.umd.cs.findbugs	Main package for the FindBugs application - contains the engine class (FindBugs), the object model classes for bug instances (BugInstance, BugAnnotation), and other miscellany.
edu.umd.cs.findbugs.ba	A bytecode analysis framework for BCEL, providing CFG construction, generic dataflow analysis, and a variety of specific dataflow analyses.
edu.umd.cs.findbugs.ba.heap
edu.umd.cs.findbugs.ba.npe
edu.umd.cs.findbugs.ba.type
edu.umd.cs.findbugs.ba.vna
edu.umd.cs.findbugs.classfile.analysis	Classes of objects that are the result of executing an analysis engine on a class or method. The classes in this particular package are those that are independent of any particular bytecode-analysis framework (e.g., BCEL or ASM). Two important classes in this package are ClassData, which represents the raw data of a class, and ClassInfo, which represents symbolic information parsed from the class data.
