Package org.owasp.dependencycheck.analyzer

Class NpmCPEAnalyzer

java.lang.Object

org.owasp.dependencycheck.analyzer.AbstractAnalyzer

org.owasp.dependencycheck.analyzer.CPEAnalyzer

org.owasp.dependencycheck.analyzer.NpmCPEAnalyzer

All Implemented Interfaces:

Analyzer

@ThreadSafe
public class NpmCPEAnalyzer
extends CPEAnalyzer

NpmCPEAnalyzer takes a project dependency and attempts to discern if there is an associated CPE. Unlike the CPEAnalyzer, the NpmCPEAnalyzer only includes product and vendor associates known to be related to node from the NVD data set. It uses the evidence contained within the dependency to search the Lucene index.
