beejava

compiles java 'opcode' to bytecode.

project status: early stage

• At this moment a complete compile cycle is guaranteed (unittested) for a really simple class.

Code example below, but the API will change without doubt.

BeeSource createEmptyClass() {
    return BeeSource.builder()
           .withClassFileVersion(Version.V14)
           .withPackage("nl.sander.beejava.test")
           .withAccessFlags(PUBLIC, SUPER)
           .withSimpleName("EmptyBean")
           .withSuperClass(Object.class) // Not mandatory, like in java sourcecode
           .withConstructors(createDefaultConstructor()) // There's no default constructor in beejava. The user must always add them
           .build();
}

BeeConstructor createDefaultConstructor() {
    return BeeConstructor.builder()
            .withAccessFlags(MethodAccessFlags.PUBLIC)
            .withCode(
                    line(0, LD_VAR, Ref.THIS),
                    line(1, INVOKE, Ref.SUPER, "<init>", "()"),
                    line(5, RETURN))
            .build();
 }
