Constructor Details

YarnAuditAnalyzer

public YarnAuditAnalyzer()

Method Details

getAnalyzerEnabledSettingKey

protected String getAnalyzerEnabledSettingKey()

Description copied from class: AbstractAnalyzer

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

getFileFilter

protected FileFilter getFileFilter()

Description copied from class: AbstractFileTypeAnalyzer

Returns the FileFilter used to determine which files are to be analyzed. An example would be an analyzer that inspected Java jar files. Implementors may use FileFilterBuilder.

If the analyzer returns null it will not cause additional files to be analyzed, but will be executed against every file loaded.

Specified by:

getFileFilter in class AbstractFileTypeAnalyzer

Returns:

the file filter used to determine which files are to be analyzed

getName

public String getName()

Description copied from interface: Analyzer

Returns the name of the analyzer.

Returns:

the name of the analyzer.

getAnalysisPhase

public AnalysisPhase getAnalysisPhase()

Description copied from interface: Analyzer

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

Returns:

the phase that the analyzer is intended to run in.

prepareFileTypeAnalyzer

protected void prepareFileTypeAnalyzer(Engine engine)
                                throws InitializationException

Initializes the analyzer once before any analysis is performed.

Overrides:

prepareFileTypeAnalyzer in class AbstractNpmAnalyzer

Parameters:

engine - a reference to the dependency-check engine

Throws:

InitializationException - if there's an error during initialization

analyzeDependency

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

Analyzes the yarn lock file to determine vulnerable dependencies. Uses yarn audit --offline to generate the payload to be sent to the NPM API.

Specified by:

analyzeDependency in class AbstractAnalyzer

Parameters:

dependency - the yarn lock file

engine - the analysis engine

Throws:

AnalysisException - thrown if there is an error analyzing the file
