Field Summary

Fields

Modifier and Type	Field and Description
static RioSetting<List<DatatypeHandler>>	DATATYPE_HANDLERS Setting used to specify which DatatypeHandler implementations are to be used for a given parser configuration.
static RioSetting<Boolean>	FAIL_ON_UNKNOWN_DATATYPES Boolean setting for parser to determine whether to fail parsing if datatypes are not recognised.
static RioSetting<Boolean>	FAIL_ON_UNKNOWN_LANGUAGES Boolean setting for parser to determine whether to fail parsing if languages are not recognised.
static RioSetting<List<LanguageHandler>>	LANGUAGE_HANDLERS Setting used to specify which LanguageHandler implementations are to be used for a given parser configuration.
static RioSetting<LargeLiteralHandling>	LARGE_LITERALS_HANDLING Boolean setting for parser to determine whether parser should preserve, truncate, drop, or otherwise manipulate statements that contain long literals.
static RioSetting<Long>	LARGE_LITERALS_LIMIT If LARGE_LITERALS_HANDLING is set to LargeLiteralHandling.PRESERVE, which it is by default, then the value of this setting is not used.
static RioSetting<Boolean>	NORMALIZE_DATATYPE_VALUES Boolean setting for parser to determine whether recognised datatypes need to have their values be normalized.
static RioSetting<Boolean>	NORMALIZE_LANGUAGE_TAGS Boolean setting for parser to determine whether languages need to be normalized, and to which format they should be normalised.
static RioSetting<Boolean>	PRESERVE_BNODE_IDS Boolean setting for parser to determine whether parser should attempt to preserve identifiers for blank nodes.
static RioSetting<Boolean>	VERIFY_DATATYPE_VALUES Boolean setting for parser to determine whether values for recognised datatypes are to be verified.
static RioSetting<Boolean>	VERIFY_LANGUAGE_TAGS Boolean setting for parser to determine whether languages are to be verified based on a given set of definitions for valid languages.
static RioSetting<Boolean>	VERIFY_RELATIVE_URIS Boolean setting for parser to determine whether relative URIs are verified.

Field Detail

VERIFY_DATATYPE_VALUES

public static final RioSetting<Boolean> VERIFY_DATATYPE_VALUES

Boolean setting for parser to determine whether values for recognised datatypes are to be verified.

Verification is performed using registered DatatypeHandlers.

Defaults to true.

Since:

2.7.0

FAIL_ON_UNKNOWN_DATATYPES

public static final RioSetting<Boolean> FAIL_ON_UNKNOWN_DATATYPES

Boolean setting for parser to determine whether to fail parsing if datatypes are not recognised.

Datatypes are recognised based on matching one of the registered DatatypeHandlers.

Defaults to false.

Since:

2.7.0

NORMALIZE_DATATYPE_VALUES

public static final RioSetting<Boolean> NORMALIZE_DATATYPE_VALUES

Boolean setting for parser to determine whether recognised datatypes need to have their values be normalized.

Normalization is performed using registered DatatypeHandlers.

Defaults to false.

Since:

2.7.0

DATATYPE_HANDLERS

public static final RioSetting<List<DatatypeHandler>> DATATYPE_HANDLERS

Setting used to specify which DatatypeHandler implementations are to be used for a given parser configuration.

Defaults to an XMLSchema DatatypeHandler implementation based on DatatypeHandler.XMLSCHEMA and an RDF DatatypeHandler implementation based on DatatypeHandler.RDFDATATYPES.

Since:

2.7.0

FAIL_ON_UNKNOWN_LANGUAGES

public static final RioSetting<Boolean> FAIL_ON_UNKNOWN_LANGUAGES

Boolean setting for parser to determine whether to fail parsing if languages are not recognised.

Languages are recognised based on matching one of the registered LanguageHandlers.

Defaults to false.

Since:

2.7.0

VERIFY_LANGUAGE_TAGS

public static final RioSetting<Boolean> VERIFY_LANGUAGE_TAGS

Boolean setting for parser to determine whether languages are to be verified based on a given set of definitions for valid languages.

Verification is performed using registered LanguageTagHandlers.

Defaults to true.

Since:

2.7.0

NORMALIZE_LANGUAGE_TAGS

public static final RioSetting<Boolean> NORMALIZE_LANGUAGE_TAGS

Boolean setting for parser to determine whether languages need to be normalized, and to which format they should be normalised.

Normalization is performed using registered LanguageTagHandlers.

Defaults to false.

Since:

2.7.0

LANGUAGE_HANDLERS

public static final RioSetting<List<LanguageHandler>> LANGUAGE_HANDLERS

Setting used to specify which LanguageHandler implementations are to be used for a given parser configuration.

Defaults to an RFC3066 LanguageHandler implementation based on LanguageHandler.RFC3066.

Since:

2.7.0

VERIFY_RELATIVE_URIS

public static final RioSetting<Boolean> VERIFY_RELATIVE_URIS

Boolean setting for parser to determine whether relative URIs are verified.

Defaults to true.

Since:

2.7.0

PRESERVE_BNODE_IDS

public static final RioSetting<Boolean> PRESERVE_BNODE_IDS

Boolean setting for parser to determine whether parser should attempt to preserve identifiers for blank nodes. If the blank node did not have an identifier in the document a new identifier will be generated for it.

Defaults to false.

Since:

2.7.0

LARGE_LITERALS_HANDLING

public static final RioSetting<LargeLiteralHandling> LARGE_LITERALS_HANDLING

Boolean setting for parser to determine whether parser should preserve, truncate, drop, or otherwise manipulate statements that contain long literals. The maximum length of literals if this setting is set to truncate or drop is configured using LARGE_LITERALS_LIMIT.

Defaults to LargeLiteralHandling.PRESERVE.

Since:

2.7.0

LARGE_LITERALS_LIMIT

public static final RioSetting<Long> LARGE_LITERALS_LIMIT

If LARGE_LITERALS_HANDLING is set to LargeLiteralHandling.PRESERVE, which it is by default, then the value of this setting is not used.

If LARGE_LITERALS_HANDLING is set to LargeLiteralHandling.DROP , then the value of this setting corresponds to the maximum number of bytes for a literal before the statement it is a part of is dropped silently by the parser.

If LARGE_LITERALS_HANDLING is set to LargeLiteralHandling.TRUNCATE , then the value of this setting corresponds to the maximum number of bytes for a literal before the value is truncated.

Defaults to 1048576 bytes, which is equivalent to 1 megabyte.

Since:

2.7.0
