public InjectionSink(edu.umd.cs.findbugs.Detector detector,
                     String bugType,
                     int originalPriority,
                     edu.umd.cs.findbugs.ba.ClassContext classContext,
                     org.apache.bcel.classfile.Method method,
                     org.apache.bcel.generic.InstructionHandle instructionHandle,
                     String sinkMethod)

Constructs the instance and stores immutable values for reporting

Parameters:

detector - detctor for reporting

bugType - reported bug type

originalPriority - original priority (without sink confirmation)

classContext - class with the sink

method - method with the sink

instructionHandle - instruction with the sink

sinkMethod - called method (sink)

Throws:

NullPointerException - if any argument is null

Method Detail

updateSinkPriority

public boolean updateSinkPriority(int priority)

Updates the priority if it is higher (which means lower number)

Parameters:

priority - potential new priority

Returns:

true if updated, false otherwise

addLine

public void addLine(edu.umd.cs.findbugs.SourceLineAnnotation line)

Adds a line with tainted source or path for reporting

Parameters:

line - line to add

addLines

public void addLines(Collection<TaintLocation> locations)

Adds lines with tainted source or path for reporting

Parameters:

locations - collection of locations used to extract lines

addUnknownSources

public void addUnknownSources(Collection<TaintLocation> sources)

generateBugInstance

public edu.umd.cs.findbugs.BugInstance generateBugInstance(boolean taintedInsideMethod)

Uses immutable values, updated priority and added lines for reporting

Parameters:

taintedInsideMethod - true if not influenced by method arguments

Returns:

new bug instance filled with information

equals

public boolean equals(Object obj)

Overrides:

equals in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object
