Class CpeMemoryIndex

java.lang.Object

org.owasp.dependencycheck.data.cpe.AbstractMemoryIndex

org.owasp.dependencycheck.data.cpe.CpeMemoryIndex

All Implemented Interfaces:

AutoCloseable, MemoryIndex

@ThreadSafe
public final class CpeMemoryIndex
extends AbstractMemoryIndex

An in memory Lucene index that contains the vendor/product combinations from the CPE (application) identifiers within the NVD CVE data.

This is the last remaining singleton in dependency-check-core; The use of this singleton - while it may not technically be thread-safe (one database used to build this index may not have the same entries as another) the risk of this is currently believed to be small. As this memory index consumes a large amount of memory we will remain using the singleton pattern for now.
