Field Summary

Fields

Modifier and Type	Field	Description
protected QueryResultHandler	handler	The QueryResultHandler that will handle the parsed query results.
protected ValueFactory	valueFactory	The ValueFactory to use for creating RDF model objects.

Constructor Summary

Constructors

Modifier	Constructor	Description
protected	AbstractQueryResultParser()	Creates a new parser base that, by default, will use the global instance of SimpleValueFactory to create Value objects.
protected	AbstractQueryResultParser(ValueFactory valueFactory)	Creates a new parser base that will use the supplied ValueFactory to create Value objects.

Method Summary

Modifier and Type	Method	Description
ParseErrorListener	getParseErrorListener()
ParseLocationListener	getParseLocationListener()
ParserConfig	getParserConfig()	Retrieves the current parser configuration as a single object.
Collection<RioSetting<?>>	getSupportedSettings()
<T> QueryResultParser	set(RioSetting<T> setting, T value)	Set a setting on the parser, and return this parser object to allow chaining.
QueryResultParser	setParseErrorListener(ParseErrorListener el)	Sets the ParseErrorListener that will be notified of any errors that this parser finds during parsing.
QueryResultParser	setParseLocationListener(ParseLocationListener el)	Sets the ParseLocationListener that will be notified of the parser's progress during the parse process.
QueryResultParser	setParserConfig(ParserConfig config)	Sets all supplied parser configuration options.
QueryResultParser	setQueryResultHandler(QueryResultHandler handler)	Sets the QueryResultHandler to be used when parsing query results using QueryResultParser.parseQueryResult(InputStream).
QueryResultParser	setValueFactory(ValueFactory valueFactory)	Sets the ValueFactory that the parser will use to create Value objects for the parsed query result.

Constructor Details

AbstractQueryResultParser

protected AbstractQueryResultParser()

Creates a new parser base that, by default, will use the global instance of SimpleValueFactory to create Value objects.

AbstractQueryResultParser

protected AbstractQueryResultParser(ValueFactory valueFactory)

Creates a new parser base that will use the supplied ValueFactory to create Value objects.

Method Details

setValueFactory

public QueryResultParser setValueFactory(ValueFactory valueFactory)

Description copied from interface: QueryResultParser

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

Specified by:

setValueFactory in interface QueryResultParser

Parameters:

valueFactory - The value factory that the parser should use.

setQueryResultHandler

public QueryResultParser setQueryResultHandler(QueryResultHandler handler)

Description copied from interface: QueryResultParser

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

Specified by:

setQueryResultHandler in interface QueryResultParser

Parameters:

handler - The QueryResultHandler to use for handling results.

setParserConfig

public QueryResultParser setParserConfig(ParserConfig config)

Description copied from interface: QueryResultParser

Sets all supplied parser configuration options.

Specified by:

setParserConfig in interface QueryResultParser

Parameters:

config - a parser configuration object.

getParserConfig

public ParserConfig getParserConfig()

Description copied from interface: QueryResultParser

Retrieves the current parser configuration as a single object.

Specified by:

getParserConfig in interface QueryResultParser

Returns:

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

setParseErrorListener

public QueryResultParser setParseErrorListener(ParseErrorListener el)

Description copied from interface: QueryResultParser

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

Specified by:

setParseErrorListener in interface QueryResultParser

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.

getParseErrorListener

public ParseErrorListener getParseErrorListener()

setParseLocationListener

public QueryResultParser setParseLocationListener(ParseLocationListener el)

Description copied from interface: QueryResultParser

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

Specified by:

setParseLocationListener in interface QueryResultParser

Parameters:

el - 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.

getParseLocationListener

public ParseLocationListener getParseLocationListener()

getSupportedSettings

public Collection<RioSetting<?>> getSupportedSettings()

Specified by:

getSupportedSettings in interface QueryResultParser

Returns:

A collection of RioSettings that are supported by this QueryResultParser.

set

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

Description copied from interface: QueryResultParser

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

Specified by:

set in interface QueryResultParser

Parameters:

setting - The setting to change.
