Class PatternRuleQueryBuilder

java.lang.Object

org.languagetool.dev.index.PatternRuleQueryBuilder

public class PatternRuleQueryBuilder
extends Object

A factory class for building a Lucene Query from a PatternRule. The query requires an index where each document contains only one sentence. It returns potential matches, i.e. LanguageTool still needs to run over the matches to make sure there is indeed an error.
