Package ome.services.blitz.util

Class ParamsCache

  • All Implemented Interfaces:
    org.springframework.beans.factory.Aware, org.springframework.context.ApplicationContextAware
    public class ParamsCache
extends java.lang.Object
implements org.springframework.context.ApplicationContextAware
    Caching replacement of ParamsHelper which maintains an OriginalFile ID+SHA1-to-JobParams mapping in memory rather than storing ParseJob instances in the database. All scripts are read once on start and them subsequently based on the omero.scripts.cache.cron setting. JobParams instances may be removed from the cache based on the omero.scripts.cache.spec setting. If a key is not present in the cache on getParams(Long, String, Current) then an attempt will be made to load it. Any exceptions thrown will be propagated to the caller.
    Since:
    5.1.2
