rascal-0.34.0
flybytes-0.2.3

Provides a native interface to Java objects via class and object reflection.

Usage​

import lang::flybytes::Mirror;

Source code​

http://github.com/usethesource/flybytes/blob/main/src/lang/flybytes/Mirror.rsc

Dependencies​

import lang::flybytes::Syntax;

Description​

Using this Mirror representation you can test generated class files by loading the class and executing static methods on the classes, getting static fields, allocating new instances, calling methods on these instances, etc. There is also support for native arrays.

data Mirror​

data Mirror  
     = class(str class, 
        Mirror (Signature method, list[Mirror] args) invokeStatic,
        Mirror (str name) getStatic,
        Mirror (Signature constructor, list[Mirror] args) newInstance,
        Mirror (Type \type) getAnnotation)
     | object(Mirror classMirror, 
        Mirror (Signature method, list[Mirror] args) invoke,
        Mirror (str name) getField,
        &T  (type[&T] expect) toValue)
     | array(int () length,
        Mirror (int index) load)
     | \null()
     ;
