parseQueryResult

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

Description copied from interface: QueryResultParser

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

Specified by:

parseQueryResult in interface QueryResultParser

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 QueryResultParser.setQueryResultHandler(QueryResultHandler) throws an exception.

parseQueryResultInternal

protected boolean parseQueryResultInternal(InputStream in,
                                           boolean attemptParseBoolean,
                                           boolean attemptParseTuple)
                                    throws IOException,
                                           QueryResultParseException,
                                           QueryResultHandlerException

Throws:

IOException

QueryResultParseException

QueryResultHandlerException

reportWarning

protected void reportWarning(String msg)

getCompulsoryXmlPropertySettings

public Collection<RioSetting<?>> getCompulsoryXmlPropertySettings()

Returns a collection of settings that will always be set as XML parser properties using XMLReader.setProperty(String, Object)

Subclasses can override this to specify more supported settings.

Returns:

A collection of RioSettings that indicate which properties will always be setup using XMLReader.setProperty(String, Object).

getCompulsoryXmlFeatureSettings

public Collection<RioSetting<Boolean>> getCompulsoryXmlFeatureSettings()

Returns a collection of settings that will always be set as XML parser features using XMLReader.setFeature(String, boolean).

Subclasses can override this to specify more supported settings.

Returns:

A collection of RioSettings that indicate which boolean settings will always be setup using XMLReader.setFeature(String, boolean).

getOptionalXmlPropertySettings

public Collection<RioSetting<?>> getOptionalXmlPropertySettings()

Returns a collection of settings that will be used, if set in AbstractQueryResultParser.getParserConfig(), as XML parser properties using XMLReader.setProperty(String, Object)

Subclasses can override this to specify more supported settings.

Returns:

A collection of RioSettings that indicate which properties can be setup using XMLReader.setProperty(String, Object).

getOptionalXmlFeatureSettings

public Collection<RioSetting<Boolean>> getOptionalXmlFeatureSettings()

Returns a collection of settings that will be used, if set in AbstractQueryResultParser.getParserConfig(), as XML parser features using XMLReader.setFeature(String, boolean).

Subclasses can override this to specify more supported settings.

Returns:

A collection of RioSettings that indicate which boolean settings can be setup using XMLReader.setFeature(String, boolean).

getSupportedSettings

public Collection<RioSetting<?>> getSupportedSettings()

Specified by:

getSupportedSettings in interface QueryResultParser

Overrides:

getSupportedSettings in class AbstractQueryResultParser

Returns:

A collection of RioSettings that are supported by this QueryResultParser.
