Method Details

getName

public String getName()

Returns the name of the analyzer.

Returns:

the name of the analyzer.

getAnalysisPhase

public AnalysisPhase getAnalysisPhase()

Returns the phase that the analyzer is intended to run in.

Returns:

the phase that the analyzer is intended to run in.

getAnalyzerEnabledSettingKey

protected String getAnalyzerEnabledSettingKey()

Returns the setting key to determine if the analyzer is enabled.

Specified by:

getAnalyzerEnabledSettingKey in class AbstractAnalyzer

Returns:

the key for the analyzer's enabled property

analyzeDependency

protected void analyzeDependency(Dependency dependency,
 Engine engine)
                          throws AnalysisException

Analyzes the dependencies and removes bad/incorrect CPE associations based on various heuristics.

Specified by:

analyzeDependency in class AbstractAnalyzer

Parameters:

dependency - the dependency to analyze.

engine - the engine that is scanning the dependencies

Throws:

AnalysisException - is thrown if there is an error reading the JAR file.

removeBadMatches

protected void removeBadMatches(Dependency dependency)

Removes bad CPE matches for a dependency. Unfortunately, right now these are hard-coded patches for specific problems identified when testing this on a LARGE volume of jar files.

Parameters:

dependency - the dependency to analyze
