Package com.vaadin.flow.server.scanner

Class ReflectionsClassFinder

java.lang.Object

com.vaadin.flow.server.scanner.ReflectionsClassFinder

All Implemented Interfaces:

com.vaadin.flow.server.frontend.scanner.ClassFinder, Serializable

public class ReflectionsClassFinder
extends Object
implements com.vaadin.flow.server.frontend.scanner.ClassFinder

A class finder using io.github.classgraph.

This implementation uses the ClassGraph library for fast classpath scanning. ClassGraph parses bytecode directly without loading classes, making it significantly faster than reflection-based approaches.

Note: Despite the class name, this implementation uses ClassGraph library, not the org.reflections library. The class name is maintained for backward compatibility.

Since:

2.0
