Interface IExtensionFactory

All Known Implementing Classes:

BSBMExtensionFactory, CompressedTimestampExtensionFactory, DefaultExtensionFactory, NoExtensionFactory, SampleExtensionFactory

public interface IExtensionFactory

IExtensionFactories are responsible for enumerating what extensions are supported for a particular database configuration. Bigdata comes packaged with a SampleExtensionFactory that supplies two starter extensions - the EpochExtension (for representing time since the epoch as a long integer) and the ColorsEnumExtension (a sample extension for how to represent an enumeration via inline literals).

Method Summary

Methods

Modifier and Type	Method and Description
Iterator<IExtension<? extends BigdataValue>>	getExtensions() Return the supported extensions.
void	init(IDatatypeURIResolver resolver, ILexiconConfiguration<BigdataValue> config) This will be called very early in the IExtensionFactory lifecycle so that the BlobIVs for the IExtension's datatype URIs will be on hand when needed.

Method Detail

init

void init(IDatatypeURIResolver resolver,
        ILexiconConfiguration<BigdataValue> config)

This will be called very early in the IExtensionFactory lifecycle so that the BlobIVs for the IExtension's datatype URIs will be on hand when needed. Also gets other relevant configuration information from the lexicon such as whether or not to inline xsd:datetimes and what timezone to use to do so.

Parameters:

resolver - The interface used to resolve an URI to an BigdataURI.

config - The ILexiconConfiguration.

getExtensions

Iterator<IExtension<? extends BigdataValue>> getExtensions()

Return the supported extensions.
