Package org.apache.lucene.sandbox.facet.utils

Class FacetBuilder

java.lang.Object

org.apache.lucene.sandbox.facet.utils.FacetBuilder

Direct Known Subclasses:

CommonFacetBuilder, LongValueFacetBuilder, TaxonomyFacetBuilder

public abstract class FacetBuilder
extends Object

End-to-end (request, collection and results) management of a single facet request.

Use CommonFacetBuilder unless there is a facet type specific implementation, such as TaxonomyFacetBuilder. Use with FacetOrchestrator or DrillSidewaysFacetOrchestrator.

Note that you need separate FacetBuilder instances even for very similar requests, e.g. when sort order is the only difference. FacetOrchestrator and DrillSidewaysFacetOrchestrator

It's an abstract class, not an interface, to define some methods as package private as they should only be called by FacetOrchestrator or DrillSidewaysFacetOrchestrator.

WARNING: This API is experimental and might change in incompatible ways in the next release.
