Interface ILexiconConfiguration<V extends BigdataValue>

All Known Implementing Classes:

LexiconConfiguration

public interface ILexiconConfiguration<V extends BigdataValue>

Configuration determines which RDF Values are inlined into the statement indices rather than being assigned term identifiers by the lexicon.

Method Summary

Methods

Modifier and Type	Method and Description

V	asValueFromVocab(IV<?,?> iv) Return the Value for that IV iff the IV is declared in the Vocabulary.
IV	createInlineIV(org.openrdf.model.Value value) Create an inline IV for the supplied RDF value if inlining is supported for the supplied RDF value.
int	getBlobsThreshold() Return the threshold at which a literal would be stored in the LexiconKeyOrder.BLOBS index.
GeoSpatialConfig	getGeoSpatialConfig() Return the geospatial datatype configuration.
TimeZone	getInlineDateTimesTimeZone() Return the default time zone to be used for inlining.
String	getInlineURILocalNameFromDelegate(org.openrdf.model.URI namespace, AbstractLiteralIV<BigdataLiteral,?> delegate) Inflate the localName portion of an inline URI using its storage delegate.

Method Detail

getMaxInlineStringLength

int getMaxInlineStringLength()

Return the maximum length of a Unicode string which may be inlined into the statement indices. This applies to blank node IDs, literal labels (including the XSDStringExtension), local names of URIs, etc.

AbstractTripleStore.Options#MAX_INLINE_TEXT_LENGTH

isInlineTextLiterals

boolean isInlineTextLiterals()

See Also:

AbstractTripleStore.Options#INLINE_TEXT_LITERALS

isInlineLiterals

boolean isInlineLiterals()

Return true if datatype literals are being inlined into the statement indices.

isInlineDateTimes

boolean isInlineDateTimes()

Return true if xsd:datetime literals are being inlined into the statement indices.

isGeoSpatial

boolean isGeoSpatial()

Return true if GeoSpatial support is enabled.

getGeoSpatialConfig

GeoSpatialConfig getGeoSpatialConfig()

Return the geospatial datatype configuration.

getInlineDateTimesTimeZone

TimeZone getInlineDateTimesTimeZone()

Return the default time zone to be used for inlining.

getBlobsThreshold

int getBlobsThreshold()

Return the threshold at which a literal would be stored in the LexiconKeyOrder.BLOBS index.

See Also:

AbstractTripleStore.Options#BLOBS_THRESHOLD

isBlobsDisabled

boolean isBlobsDisabled()

Return true iff the BLOBS index has been disabled.

Disable BLOBS indexing completely for GPU

createInlineIV

IV createInlineIV(org.openrdf.model.Value value)

Create an inline IV for the supplied RDF value if inlining is supported for the supplied RDF value.

Note: If the supplied RDF value is a BigdataValue then the IV will be set as a side-effect and will be available from BigdataValue.getIV().

Parameters:

value - The RDF value

Returns:

The inline IV -or- null if the Value can not be represented by an IV.

getInlineURILocalNameFromDelegate

String getInlineURILocalNameFromDelegate(org.openrdf.model.URI namespace,
                                       AbstractLiteralIV<BigdataLiteral,?> delegate)

Inflate the localName portion of an inline URI using its storage delegate.

Parameters:

namespace - the uris's prefix

delegate - the storage delegate

Returns:

the inflated localName

asValue

V asValue(LiteralExtensionIV<?> iv)

Create an RDF value from an AbstractInlineExtensionIV. The "extension" IV MUST be registered with the Vocabulary.

For LiteralExtensionIV, this through an internal catalog of IExtensions to find one that knows how to handle the extension datatype from the supplied LiteralExtensionIV. This is the historical use case.

Parameters:

iv - the extension IV

Returns:

The RDF Value

asValueFromVocab

V asValueFromVocab(IV<?,?> iv)

Return the Value for that IV iff the IV is declared in the Vocabulary.

Parameters:

iv - The IV.

Returns:

The Value -or- null if the IV was not declared in the Vocabulary.

initExtensions

void initExtensions(IDatatypeURIResolver resolver)

Initialize the extensions, which need to resolve their datatype URIs into term ids.

getValueFactory

BigdataValueFactory getValueFactory()

Return the value factory for the lexicon.

isInlineDatatypeToTextIndex

boolean isInlineDatatypeToTextIndex(org.openrdf.model.URI datatype)

Should the specified datatype be included in the text index (even though it is an inline datatype, for example IPv4).

getTypeHandlers

Iterable<IMathOpHandler> getTypeHandlers()

Get iterator over registered type handlers.
