All Implemented Interfaces:

LuceneSearchMapperRegistry

public class ThreadCachedSearchMapperRegistry
extends Object
implements LuceneSearchMapperRegistry

A facade onto the PluggableLuceneSearchMapperRegistry which will first look for a ThreadLocal cache of available search mappers before delegating.

This is necessary due to the current slowness involved in looking up available search mappers from the plugin subsystem (see CONF-11920). The architectural strategy in Confluence is to move away from diverse caches spread about the software - this class is a compromise in that the cache it uses will only exist for the duration of the single search being performed.

This class should be considered in conjunction with the LuceneSearchManager which is responsible for creating and removing the thread local cache of available mappers.
