All Implemented Interfaces:

java.io.Closeable, java.lang.AutoCloseable

public class LanguagePrefixedTextAnalyzer
extends org.apache.lucene.analysis.Analyzer

A custom Analyzer type, aware about the Solr IndexSchema, which delegates the processing to a custom TokenStream. Although the core part of the logic needed for that dynamic assignment is in LanguagePrefixedTokenStream the actors group is also composed by:

• a TextField subclass (this class)
• a custom Analyzer
• a custom token stream LanguagePrefixedTokenStream

Both of them have no specific logic: they exist only because the components involved in the analysis chain don't have access to the IndexSchema instance (e.g. a Tokenizer is a schema concept, while IndexSchema belongs to Solr classes).
