It makes easier an access to Java 6 compiler API. This library enables compiling, executing and modifying Java-code dynamically while the program is working. UsageDynamic class compilationString classDef = "public class MyClass {"+ " public String toString() {" + " return \\"MyClass\\";" + " }"+ "}";RuntimeClass runtimeClass = new RuntimeClass(classDef);System.out.println(runtimeClass.newInstance());Dynamic block executionRuntimeBlock sum = new RuntimeBlock( "return (Integer)params[0]+(Integer)params[1];");System.out.println(sum.invoke(1, 2));System.out.println(sum.invoke(5, 100)); Dynamic class modificationpublic class ClassToModify { public String simpleMethod(String text) { System.out.println("Text: " + text); return text; }}...MutableRuntimeClass<ClassToModify> clazz = new MutableRuntimeClass<ClassToModify>(ClassToModify.class);ClassToModify instance = clazz.newInstance(new SimpleMutator() { @Override public void onBeforeMethod(Object instance, Method method, Object... params) { System.out.println("Before method: " + method.getName() + ", params: " + Arrays.toString(params)); } @Override public Object onAfterMethod(Object instance, Method method, Object result, Object... params) { System.out.println("After method: " + method.getName() + ", params: " + Arrays.toString(params)); return result; }});instance.simpleMethod("Test mutable class!!!");External links
