Class ReflectiveELProxyFactory

java.lang.Object

io.micronaut.el.interpreter.reflection.ReflectiveELProxyFactory

All Implemented Interfaces:

ELProxyFactory

@Internal
public final class ReflectiveELProxyFactory
extends Object
implements ELProxyFactory

Implements a functional interface nothing described in advance, by discovering its single abstract method and standing in for it with a Proxy.

This is the reflection the coercion of the section 1.23.2 needs when the interface is an application's own and the method taking it was selected at evaluation time, so nothing could name it earlier. It lives here because of that: without this module the coercion does not apply, and an application that wants it without reflection registers the interface with ELMethodRegistry.functionalInterface.

Since:

1.1
