public class Annotation extends Object:

Object

└ Annotation

Runtime representation of an annotation attached to a reflected type, constructor, method, property, attribute or parameter.

The arguments map stores annotation argument values as source text. This keeps reflection lightweight and avoids guessing a runtime boxed value for enum constants or type references. argumentTypes exposes the token kind recorded by the compiler (String, Int, Identifier, ...).

Example

import klyn.databases.entities

@Entity(tableName="T_Users")
public class User:
pass

annotation = User.type.annotations[0]
assert annotation.name == "Entity"
assert annotation.argument("tableName") == "T_Users"
