Class InMemSpdxStore

java.lang.Object

org.spdx.storage.simple.InMemSpdxStore

All Implemented Interfaces:

AutoCloseable, org.spdx.storage.IModelStore

public class InMemSpdxStore
extends Object
implements org.spdx.storage.IModelStore

In memory implementation of an SPDX store

This implementation primarily uses ConcurrentHashMaps.

It is designed to be thread-safe and low CPU utilization. It may use significant amounts of memory for larger SPDX documents.
