Class LoadedFieldSetFactory
java.lang.Object
edu.umd.cs.findbugs.classfile.engine.bcel.AnalysisFactory<LoadedFieldSet>
edu.umd.cs.findbugs.classfile.engine.bcel.LoadedFieldSetFactory
- All Implemented Interfaces:
IAnalysisEngine<MethodDescriptor,
,LoadedFieldSet> IMethodAnalysisEngine<LoadedFieldSet>
Factory to determine which fields are loaded and stored by the instructions
in a method, and the overall method. The main purpose is to support efficient
redundant load elimination and forward substitution in ValueNumberAnalysis
(there is no need to remember stores of fields that are never read, or loads
of fields that are only loaded in one location). However, it might be useful
for other kinds of analysis.
The tricky part is that in addition to fields loaded and stored with get/putfield and get/putstatic, we also try to figure out field accessed through calls to inner-class access methods.
