What is Reflect?
Reflect is a classpath scanner and filter, using it you can scan your classpath, filter your resources, classes, fields, methods and constructors.
It's immutable, fluent and simple, so it's also thread safe and easy to use.
It's inspired by Reflections and Guava ClassPath.
Usage
// Scanner
Resources rs1 = Scanner.pkgs("io.ytcode.reflect").scan();
for (Resource r : rs1) {
System.out.println(r);
}
Resources rs2 = Scanner.paths("/io/ytcode/reflect/").scan();
System.out.println(rs2.size());
Resources rs3 = Scanner.paths("/").scan();
System.out.println(rs3.size());
Resources rs4 =
Scanner.from(
ImmutableSet.of(
ClassLoader.getSystemClassLoader(),
ClassLoader.getSystemClassLoader().getParent()),
ImmutableSet.of("/io/ytcode/reflect/clazz/", "/io/ytcode/reflect/resource/"),
false)
.scan();
System.out.println(rs4.size());
// Resources
Resources rs1 = Scanner.paths("/io/ytcode/reflect/").scan();
Resources rs2 = rs1.pattern(".*/resource/.*").suffix(".class");
System.out.println(rs2.size());
Resources rs3 =
rs1.filter(
new Predicate<Resource>() {
@Override
public boolean apply(Resource r) {
return r.name().endsWith(".xml");
}
});
System.out.println(rs3.size());
// Classes
Classes cs1 = Scanner.paths("/io/ytcode/reflect/").scan().classes();
Classes cs2 = cs1.subTypeOf(Filterable.class);
for (Class<?> c : cs2) {
System.out.println(c);
}
Classes cs3 = cs1.annotatedWith(Beta.class).filter(Predicates.<Class<?>>equalTo(Classes.class));
System.out.println(cs3.size());
Classes cs4 = cs1.modifiers(Modifier.PUBLIC, Modifier.ABSTRACT);
System.out.println(cs4.size());
// Fields
Fields fs1 = Scanner.paths("/io/ytcode/reflect/").scan().classes().fields();
Fields fs2 =
fs1.annotatedWith(Beta.class)
.filter(
new Predicate<Field>() {
@Override
public boolean apply(Field f) {
return Modifier.isStatic(f.getModifiers());
}
});
System.out.println(fs2);
Fields fs3 = fs1.modifiers(Modifier.PUBLIC, Modifier.STATIC);
System.out.println(fs3);
// Methods
Methods ms1 = Scanner.paths("/io/ytcode/reflect/").scan().classes().methods();
Methods ms2 =
ms1.filter(
new Predicate<Method>() {
@Override
public boolean apply(Method m) {
return Invokable.from(m).isPublic();
}
});
System.out.println(ms2);
Methods ms3 = ms1.modifiers(Modifier.PUBLIC, Modifier.STATIC);
System.out.println(ms3);
// Constructors
Constructors cs1 = Scanner.paths("/io/ytcode/reflect/").scan().classes().constructors();
Constructors cs2 =
cs1.filter(
new Predicate<Constructor<?>>() {
@Override
public boolean apply(Constructor<?> input) {
return Invokable.from(input).isPublic();
}
});
System.out.println(cs2);
Constructors cs3 = cs1.modifiers(Modifier.PUBLIC);
System.out.println(cs3);
