Class PatternMatcher
java.lang.Object
edu.umd.cs.findbugs.ba.bcp.PatternMatcher
- All Implemented Interfaces:
- DFSEdgeTypes
public class PatternMatcher
- extends java.lang.Object
- implements DFSEdgeTypes
Match a ByteCodePattern against the code of a method, represented
by a CFG. Produces some number of ByteCodePatternMatch objects, which
indicate how the pattern matched the bytecode instructions in the method.
This code is a hack and should probably be rewritten.
