@ExperimentalApi @PublicSpi public interface


Known Indirect Subclasses


This interface is considered usable by external developers but its contracts have not stabilized.

Experimental APIs may be changed at any time before being marked @Internal or @PublicApi.


This interface is designed for plugins to implement.

Clients of @PublicSpi can expect that programs compiled against a given version will remain binary compatible with later versions of the @PublicSpi as per each product's API policy (clients should refer to each product's API policy for the exact guarantee -- usually binary compatibility is guaranteed at least across minor versions).

Note: @PublicSpi interfaces and classes are specifically designed to be implemented/extended by clients. Hence, the guarantee of binary compatibility is different to that of @PublicApi elements (if an element is both @PublicApi and @PublicSpi, both guarantees apply).

Class Overview

A custom field searcher will implement this interface if the custom field can be sorted but sorting requires multiple Lucene org.apache.lucene.search.SortField.

It is useful for hierarchical custom fields like CascadingSelectCFType that store parent-child relationship and wish to be sorted by both fields.

If a custom field wishes to sort itself, it can use the much slower method SortableCustomField.
