Method Detail

getFileFilter

protected java.io.FileFilter getFileFilter()

Returns the FileFilter

Specified by:

getFileFilter in class AbstractFileTypeAnalyzer

Returns:

the FileFilter

prepareFileTypeAnalyzer

protected void prepareFileTypeAnalyzer(Engine engine)
                                throws InitializationException

Performs validation on the configuration to ensure that the correct analyzers are in place.

Overrides:

prepareFileTypeAnalyzer in class AbstractNpmAnalyzer

Parameters:

engine - the dependency-check engine

Throws:

InitializationException - thrown if there is a configuration error

getName

public java.lang.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.

analyzeDependency

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

Description copied from class: AbstractAnalyzer

Analyzes a given dependency. If the dependency is an archive, such as a WAR or EAR, the contents are extracted, scanned, and added to the list of dependencies within the engine.

Specified by:

analyzeDependency in class AbstractAnalyzer

Parameters:

dependency - the dependency to analyze

engine - the engine scanning

Throws:

AnalysisException - thrown if there is an analysis exception

shouldSkipDependency

public static boolean shouldSkipDependency(java.lang.String name,
                                           java.lang.String version,

should process the dependency ? Will return true if you need to skip it . (e.g. dependency can't be read, or if npm audit doesn't handle it)

Parameters:

name - the name of the dependency

version - the version of the dependency

optional - is the dependency optional ?

fileExist - is the package.json available for this file ?

Returns:

should you skip this dependency ?

shouldSkipDependency

public static boolean shouldSkipDependency(java.lang.String name,
                                           java.lang.String version)

Checks if the given dependency should be skipped.

Parameters:

name - the name of the dependency to test

version - the version of the dependency to test

Returns:

true if the dependency should be skipped; otherwise false
