Constructor Detail

• CoreParser

  public CoreParser​(org.apache.lucene.analysis.Analyzer analyzer,
                    org.apache.lucene.queryParser.QueryParser parser)

  Construct an XML parser that uses a single instance QueryParser for handling UserQuery tags - all parse operations are synchronised on this parser

  Parameters:

  analyzer -

  parser - A QueryParser which will be synchronized on during parse calls.

• CoreParser

  public CoreParser​(String defaultField,
                    org.apache.lucene.analysis.Analyzer analyzer)

  Constructs an XML parser that creates a QueryParser for each UserQuery request.

  Parameters:

  defaultField - The default field name used by QueryParsers constructed for UserQuery tags

  analyzer -

• CoreParser

  protected CoreParser​(String defaultField,
                       org.apache.lucene.analysis.Analyzer analyzer,
                       org.apache.lucene.queryParser.QueryParser parser)

Method Detail

• parse

  public org.apache.lucene.search.Query parse​(InputStream xmlStream)
                                       throws ParserException

  Parses the given stream as XML file and returns a Query. By default this disallows external entities for security reasons.

  Throws:

  ParserException

• addQueryBuilder

  public void addQueryBuilder​(String nodeName,
                              QueryBuilder builder)

• addFilterBuilder

  public void addFilterBuilder​(String nodeName,
                               FilterBuilder builder)

• getEntityResolver

  protected EntityResolver getEntityResolver()

  Returns a SAX EntityResolver to be used by DocumentBuilder. By default this returns DISALLOW_EXTERNAL_ENTITY_RESOLVER, which disallows the expansion of external entities (for security reasons). To restore legacy behavior, override this method to return null.

• getErrorHandler

  protected ErrorHandler getErrorHandler()

  Subclass and override to return a SAX ErrorHandler to be used by DocumentBuilder. By default this returns null so no error handler is used. This method can be used to redirect XML parse errors/warnings to a custom logger.

• getQuery

  public org.apache.lucene.search.Query getQuery​(Element e)
                                          throws ParserException

  Specified by:

  getQuery in interface QueryBuilder

  Throws:

  ParserException

• createEntityResolver

  public static EntityResolver createEntityResolver()
