Method Detail

getQueryResultFormat

QueryResultFormat getQueryResultFormat()

Gets the query result format that this parser can parse.

Returns:

The QueryResultFormat supported by this parser.

setQueryResultHandler

QueryResultParser setQueryResultHandler(QueryResultHandler handler)

Sets the QueryResultHandler to be used when parsing query results using parseQueryResult(InputStream).

Parameters:

handler - The QueryResultHandler to use for handling results.

setValueFactory

QueryResultParser setValueFactory(ValueFactory valueFactory)

Sets the ValueFactory that the parser will use to create Value objects for the parsed query result.

Parameters:

valueFactory - The value factory that the parser should use.

setParseErrorListener

QueryResultParser setParseErrorListener(ParseErrorListener el)

Sets the ParseErrorListener that will be notified of any errors that this parser finds during parsing.

Parameters:

el - The ParseErrorListener that will be notified of errors or warnings.

Returns:

Either a copy of this parser, if it is immutable, or this object, to allow chaining of method calls.

setParseLocationListener

QueryResultParser setParseLocationListener(ParseLocationListener ll)

Sets the ParseLocationListener that will be notified of the parser's progress during the parse process.

Parameters:

ll - The ParseLocationListener that will be notified of the parser's progress.

Returns:

Either a copy of this parser, if it is immutable, or this object, to allow chaining of method calls.

parseQueryResult

void parseQueryResult(InputStream in)
               throws IOException,
                      QueryResultParseException,
                      QueryResultHandlerException

Parse the query results out of the given InputStream into the handler setup using setQueryResultHandler(QueryResultHandler).

Parameters:

in - The InputStream to parse the results from.

Throws:

IOException - If there is an exception from the InputStream.

QueryResultParseException - If the query results are not parsable by this parser.

QueryResultHandlerException - If the QueryResultHandler set in setQueryResultHandler(QueryResultHandler) throws an exception.

setParserConfig

QueryResultParser setParserConfig(ParserConfig config)

Sets all supplied parser configuration options.

Parameters:

config - a parser configuration object.

getParserConfig

ParserConfig getParserConfig()

Retrieves the current parser configuration as a single object.

Returns:

a parser configuration object representing the current configuration of the parser.

getSupportedSettings

Collection<RioSetting<?>> getSupportedSettings()

Returns:

A collection of RioSettings that are supported by this QueryResultParser.

set

<T> QueryResultParser set(RioSetting<T> setting,
                          T value)

Set a setting on the parser, and return this parser object to allow chaining.

Parameters:

setting - The setting to change.

value - The value to change.

Returns:

Either a copy of this parser, if it is immutable, or this object, to allow chaining of method calls.
