Annotation Interface ELFunctions

@Documented @Retention(RUNTIME) @Target({}) public @interface ELFunctions
Maps the public static methods of a class, and the public instance methods it declares, to Jakarta Expression Language functions.

A static method is invoked directly. An instance method is invoked on the instance the jakarta.el.ELContext provides at evaluation time: the one registered under the type with putContext, or the one an io.micronaut.el.ELBeanProvider registered in the context returns, which is how the functions declared on a Micronaut bean reach the bean.

Functions are resolved and bound at compilation time, which replaces the jakarta.el.FunctionMapper lookup performed by an interpreting implementation.
