setParserConfig

RDFParser setParserConfig(ParserConfig config)

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 RDFParser.

set

<T> RDFParser 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.

setVerifyData

@Deprecated
void setVerifyData(boolean verifyData)

Deprecated. since 2.0. Use getParserConfig() with BasicParserSettings.FAIL_ON_UNKNOWN_DATATYPES, BasicParserSettings.VERIFY_DATATYPE_VALUES, and/or BasicParserSettings.NORMALIZE_DATATYPE_VALUES instead.

Sets whether the parser should verify the data it parses (default value is true).

setPreserveBNodeIDs

void setPreserveBNodeIDs(boolean preserveBNodeIDs)

Set whether the parser should preserve bnode identifiers specified in the source (default is false).

setStopAtFirstError

@Deprecated
void setStopAtFirstError(boolean stopAtFirstError)

Deprecated. since 2.0. Use getParserConfig() with ParserConfig.addNonFatalError(RioSetting) to select which errors will not always fail the parse prematurely.

Sets whether the parser should stop immediately if it finds an error in the data (default value is true).

setDatatypeHandling

@Deprecated
void setDatatypeHandling(RDFParser.DatatypeHandling datatypeHandling)

Deprecated. since 2.0. Use getParserConfig() with BasicParserSettings.FAIL_ON_UNKNOWN_DATATYPES, BasicParserSettings.VERIFY_DATATYPE_VALUES, and/or BasicParserSettings.NORMALIZE_DATATYPE_VALUES instead.

Sets the datatype handling mode. There are three modes for handling datatyped literals: ignore , verifyand normalize . If set to ignore, no special action will be taken to handle datatyped literals. If set to verify, any literals with known (XML Schema built-in) datatypes are checked to see if their values are valid. If set to normalize, the literal values are not only checked, but also normalized to their canonical representation. The default value is verify.

Parameters:

datatypeHandling - A datatype handling option.

parse

default void parse(InputStream in)
            throws IOException,
                   RDFParseException,
                   RDFHandlerException

Parses the data from the supplied InputStream.

Parameters:

in - The InputStream from which to read the data.

Throws:

IOException - If an I/O error occurred while data was read from the InputStream.

RDFParseException - If the parser has found an unrecoverable parse error.

RDFHandlerException - If the configured statement handler has encountered an unrecoverable error.

Since:

3.5.0

parse

void parse(InputStream in,
           String baseURI)
    throws IOException,
           RDFParseException,
           RDFHandlerException

Parses the data from the supplied InputStream, using the supplied baseURI to resolve any relative URI references.

Parameters:

in - The InputStream from which to read the data.

baseURI - The URI associated with the data in the InputStream. May be null. Parsers for syntax formats that do not support relative URIs will ignore this argument.

Note that if the data contains an embedded base URI, that embedded base URI will overrule the value supplied here (see RFC 3986 section 5.1 for details).

Throws:

IOException - If an I/O error occurred while data was read from the InputStream.

RDFParseException - If the parser has found an unrecoverable parse error.

RDFHandlerException - If the configured statement handler has encountered an unrecoverable error.

parse

default void parse(Reader reader)
            throws IOException,
                   RDFParseException,
                   RDFHandlerException

Parses the data from the supplied Reader.

Parameters:

reader - The Reader from which to read the data.

Throws:

IOException - If an I/O error occurred while data was read from the InputStream.

RDFParseException - If the parser has found an unrecoverable parse error.

RDFHandlerException - If the configured statement handler has encountered an unrecoverable error.

Since:

3.5.0

parse

void parse(Reader reader,
           String baseURI)
    throws IOException,
           RDFParseException,
           RDFHandlerException

Parses the data from the supplied Reader, using the supplied baseURI to resolve any relative URI references.

Parameters:

reader - The Reader from which to read the data.

baseURI - The URI associated with the data in the InputStream. May be null. Parsers for syntax formats that do not support relative URIs will ignore this argument.

Note that if the data contains an embedded base URI, that embedded base URI will overrule the value supplied here (see RFC 3986 section 5.1 for details).

Throws:

IOException - If an I/O error occurred while data was read from the InputStream.

RDFParseException - If the parser has found an unrecoverable parse error.
