Class SearchChainResolver

java.lang.Object
com.yahoo.search.federation.sourceref.SearchChainResolver

public class SearchChainResolver extends Object
Resolves (source, provider) component specifications to a search chain invocation spec. The provider component specification is given by the entry in the queryMap with key 'source.<source-name>.provider'.

The diagram shows the relationship between source, provider and the result: (source is used to select row, provider is used to select column.) Provider id = null is used for regular search chains.
