Class NativeImageMetadataVisitor

java.lang.Object
io.micronaut.langchain4j.processor.NativeImageMetadataVisitor
All Implemented Interfaces:
io.micronaut.core.order.Ordered, io.micronaut.core.util.Toggleable, io.micronaut.inject.visitor.TypeElementVisitor<Object,Object>
@Internal public final class NativeImageMetadataVisitor extends Object implements io.micronaut.inject.visitor.TypeElementVisitor<Object,Object>
Writes the GraalVM native image metadata (META-INF/native-image/.../reachability-metadata.json) of the types LangChain4j still reads and implements reflectively: the AI service interfaces, which LangChain4j implements with Proxy and whose methods, annotations and parameters it reads reflectively, and the agentic services and agents, which LangChain4j also implements with proxies combining the agent type with its own interfaces and whose static @Agent, @Output, @ExitCondition, ... methods it invokes reflectively.

The metadata also covers the structured outputs of the services and agents and the parameters and results of the tools, whose JSON schema LangChain4j derives from their fields. Tool classes themselves need no metadata: their @Tool methods are invoked through their Micronaut ExecutableMethod.

Since:
2.4.0
