Class ReflectionMetadata

java.lang.Object

io.micronaut.langchain4j.testutils.ReflectionMetadata

public final class ReflectionMetadata
extends Object

Verifies the GraalVM reachability metadata a provider module ships for the LangChain4j types that are mapped with Jackson reflectively (the request and response types of the provider's REST API).

The expected types are the classes of the given packages of the LangChain4j jar, except the model classes (the implementations of LangChain4j's model interfaces) and their builders, the helpers (HTTP clients, mappers, parsers...), the exceptions and the anonymous classes. When LangChain4j adds a type, the verification fails and names it. Run the test with the environment variable "UPDATE_NATIVE_METADATA" set to rewrite the metadata file.
