com.yahoo.searchdefinition.processing.RankingExpressionTypeResolver

public class RankingExpressionTypeResolver
extends Processor

Resolves and assigns types to all functions in a ranking expression, and validates the types of all ranking expressions under a search instance: Some operators constrain the types of inputs, and first-and second-phase expressions must return scalar values. In addition, the existence of all referred attribute, query and constant features is ensured.

process

public void process(boolean validate,
                    boolean documentsOnly)

Description copied from class: Processor

Processes the input search definition by modifying the input search and its documents, and returns the input search definition.

Specified by:

process in class Processor

Parameters:

validate - true to throw exceptions on validation errors, false to make the best possible effort at completing processing without throwing an exception. If we are not validating, emitting warnings have no effect and can (but must not) be skipped.

documentsOnly - true to skip processing (including validation, regardless of the validate setting) of aspects not relating to document definitions (e.g rank profiles)
