LostExceptionStackTrace(edu.umd.cs.findbugs.BugReporter bugReporter)
constructs a LEST detector given the reporter to report bugs on
|
Modifier and Type | Method and Description |
---|---|
private void |
addCatchBlock(int start,
int finish)
add a catch block info record for the catch block that is guessed to be in the range of start to finish
|
org.apache.bcel.classfile.CodeException[] |
collectExceptions(org.apache.bcel.classfile.CodeException... exs)
collects all the valid exception objects (ones where start and finish are before the target
|
boolean |
isPossibleExBuilder(int excReg)
returns whether the method called might be a method that builds an exception using the original exception.
|
private static boolean |
isPre14Class(org.apache.bcel.classfile.JavaClass cls)
returns whether the class in question was compiled with a jdk less than 1.4
|
boolean |
prescreen(org.apache.bcel.classfile.Code code,
org.apache.bcel.classfile.Method method)
looks for methods that contain a catch block and an ATHROW opcode
|
private void |
removeIndeterminateHandlers(int pc) |
private void |
removePreviousHandlers(int pc) |
void |
sawOpcode(int seen)
implements the visitor to find throwing alternative exceptions from a catch block, without forwarding along the original exception
|
private boolean |
updateExceptionRegister(LostExceptionStackTrace.CatchInfo ci,
int seen,
int pc)
looks to update the catchinfo block with the register used for the exception variable.
|
void |
visitClassContext(edu.umd.cs.findbugs.ba.ClassContext classContext)
implements the visitor to make sure the jdk is 1.4 or better
|
void |
visitCode(org.apache.bcel.classfile.Code obj)
implements the visitor to filter out methods that don't throw exceptions
