Package com.yahoo.search.searchchain

Class SearchChainRegistry

java.lang.Object

com.yahoo.component.provider.ComponentRegistry<com.yahoo.component.chain.Chain<T>>

com.yahoo.processing.execution.chain.ChainRegistry<Searcher>

com.yahoo.search.searchchain.SearchChainRegistry

public class SearchChainRegistry
extends com.yahoo.processing.execution.chain.ChainRegistry<Searcher>

Contains a reference to all currently known search chains. Searchers can be fetched from this from multiple threads.

A registry can exist in two states:

• not frozen - in this state it can be edited freely by calling register(com.yahoo.component.chain.Chain<com.yahoo.search.Searcher>)
• frozen - in this state any attempt at modification throws an IlegalStateException

Registries start in the first state, moves to the second on calling freeze and stays in that state for the rest of their lifetime.
