Examples with CodeFactory spoon.reflect.factory.CodeFactory used on opensource projects

Example 1 with CodeFactory

use of spoon.reflect.factory.CodeFactory in project spoon by INRIA.

the class CompilationTest method compileTest.

@Test
public void compileTest() throws Exception {
    // contract: the modified version of classes is the one that is compiled to binary code
    final Launcher launcher = new Launcher();
    launcher.addInputResource("./src/test/resources/noclasspath/Simple.java");
    File outputBinDirectory = new File("./target/class-simple");
    if (!outputBinDirectory.exists()) {
        outputBinDirectory.mkdirs();
    }
    launcher.setBinaryOutputDirectory(outputBinDirectory);
    launcher.getEnvironment().setShouldCompile(true);
    launcher.buildModel();
    Factory factory = launcher.getFactory();
    CoreFactory core = factory.Core();
    CodeFactory code = factory.Code();
    CtClass simple = factory.Class().get("Simple");
    CtMethod method = core.createMethod();
    method.addModifier(ModifierKind.PUBLIC);
    method.setType(factory.Type().integerPrimitiveType());
    method.setSimpleName("m");
    CtBlock block = core.createBlock();
    CtReturn aReturn = core.createReturn();
    CtBinaryOperator binaryOperator = code.createBinaryOperator(code.createLiteral(10), code.createLiteral(32), BinaryOperatorKind.PLUS);
    aReturn.setReturnedExpression(binaryOperator);
    // return 10 + 32;
    block.addStatement(aReturn);
    method.setBody(block);
    simple.addMethod(method);
    launcher.getModelBuilder().compile();
    final URLClassLoader urlClassLoader = new URLClassLoader(new URL[] { outputBinDirectory.toURL() });
    Class<?> aClass = urlClassLoader.loadClass("Simple");
    Method m = aClass.getMethod("m");
    Assert.assertEquals(42, m.invoke(aClass.newInstance()));
}
