Method Detail

getValueFactory

public final BigdataValueFactory getValueFactory()

Description copied from interface: ILexiconConfiguration

Return the value factory for the lexicon.

Specified by:

getValueFactory in interface ILexiconConfiguration<V extends BigdataValue>

getMaxInlineStringLength

public int getMaxInlineStringLength()

Description copied from interface: ILexiconConfiguration

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.

Specified by:

getMaxInlineStringLength in interface ILexiconConfiguration<V extends BigdataValue>

See Also:

AbstractTripleStore.Options#MAX_INLINE_TEXT_LENGTH

isInlineTextLiterals

public boolean isInlineTextLiterals()

Specified by:

isInlineTextLiterals in interface ILexiconConfiguration<V extends BigdataValue>

See Also:

AbstractTripleStore.Options#INLINE_TEXT_LITERALS

isInlineLiterals

public boolean isInlineLiterals()

Description copied from interface: ILexiconConfiguration

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

Specified by:

isInlineLiterals in interface ILexiconConfiguration<V extends BigdataValue>

isGeoSpatial

public boolean isGeoSpatial()

Description copied from interface: ILexiconConfiguration

Return true if GeoSpatial support is enabled.

Specified by:

isGeoSpatial in interface ILexiconConfiguration<V extends BigdataValue>

getGeoSpatialConfig

public GeoSpatialConfig getGeoSpatialConfig()

Description copied from interface: ILexiconConfiguration

Return the geospatial datatype configuration.

Specified by:

getGeoSpatialConfig in interface ILexiconConfiguration<V extends BigdataValue>

isInlineDateTimes

public boolean isInlineDateTimes()

Description copied from interface: ILexiconConfiguration

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

Specified by:

isInlineDateTimes in interface ILexiconConfiguration<V extends BigdataValue>

getInlineDateTimesTimeZone

public TimeZone getInlineDateTimesTimeZone()

Description copied from interface: ILexiconConfiguration

Return the default time zone to be used for inlining.

Specified by:

getInlineDateTimesTimeZone in interface ILexiconConfiguration<V extends BigdataValue>

getBlobsThreshold

public int getBlobsThreshold()

Description copied from interface: ILexiconConfiguration

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

Specified by:

getBlobsThreshold in interface ILexiconConfiguration<V extends BigdataValue>

See Also:

AbstractTripleStore.Options#BLOBS_THRESHOLD

isBlobsDisabled

public boolean isBlobsDisabled()

Description copied from interface: ILexiconConfiguration

Return true iff the BLOBS index has been disabled.

Specified by:

isBlobsDisabled in interface ILexiconConfiguration<V extends BigdataValue>

See Also:

Disable BLOBS indexing completely for GPU

isInlineDatatypeToTextIndex

public boolean isInlineDatatypeToTextIndex(org.openrdf.model.URI dt)

Description copied from interface: ILexiconConfiguration

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

Specified by:

toString

public String toString()

toString in class Object

initExtensions

public void initExtensions(IDatatypeURIResolver resolver)

Description copied from interface: ILexiconConfiguration

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

Specified by:

initExtensions in interface ILexiconConfiguration<V extends BigdataValue>

asValue

public V asValue(LiteralExtensionIV<?> iv)

Description copied from interface: ILexiconConfiguration

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.

Specified by:

asValue in interface ILexiconConfiguration<V extends BigdataValue>

Parameters:

iv - the extension IV

Returns:

The RDF Value

asValueFromVocab

public V asValueFromVocab(IV<?,?> iv)

Description copied from interface: ILexiconConfiguration

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

Specified by:

asValueFromVocab in interface ILexiconConfiguration<V extends BigdataValue>

Parameters:

iv - The IV.

Returns:

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

createInlineIV

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

Description copied from interface: ILexiconConfiguration

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().

Specified by:

createInlineIV in interface ILexiconConfiguration<V extends BigdataValue>

Parameters:

value - The RDF value

Returns:

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

getInlineURILocalNameFromDelegate

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

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

Specified by:

getInlineURILocalNameFromDelegate in interface ILexiconConfiguration<V extends BigdataValue>

Parameters:

namespace - the uris's prefix

delegate - the storage delegate

Returns:

the inflated localName

getTypeHandlers

public Iterable<IMathOpHandler> getTypeHandlers()

Description copied from interface: ILexiconConfiguration

Get iterator over registered type handlers.

Specified by:

getTypeHandlers in interface ILexiconConfiguration<V extends BigdataValue>
