@Singleton
public class PgVectorLangchain4jEmbeddedStore
extends Object
implements Langchain4jEmbeddedStore, OpenRewriteFeature

Implements a Langchain4j embedded store using PgVector as the backend. Ensures Hikari JDBC connection pool feature is added if JDBC support is missing. and supplies OpenRewrite recipes for automated setup.

Method Details

getTitle

public String getTitle()

Specified by:

getTitle in interface Feature

Specified by:

getTitle in interface Langchain4jEmbeddedStore

Returns:

The title of the feature

getName

public String getName()

Description copied from interface: Feature

The name of the feature. It must be unique.

Specified by:

getName in interface Feature

Specified by:

getName in interface io.micronaut.core.naming.Named

Returns:

the name of the feature

getRecipes

public List<String> getRecipes(GeneratorContext generatorContext)

Specified by:

getRecipes in interface OpenRewriteFeature

processSelectedFeatures

public void processSelectedFeatures(FeatureContext featureContext)

Description copied from interface: Feature

If this method is called for a given feature then that feature was explicitly selected or was included by default as a result of DefaultFeature.shouldApply(io.micronaut.starter.options.Options, java.util.Set). This method can be implemented to allow features to modify the list of features that will apply to the project. The methods FeatureContext.addFeature(Feature) and FeatureContext.exclude(FeaturePredicate) are the primary ways to add and remove features from the context. FeatureContext.isPresent(Class) can be used to determine the existence of other features in order to make decisions.

Specified by:

processSelectedFeatures in interface Feature

Parameters:

featureContext - The feature context
