GadtryJava 工具庫集合

Gadtry是一個java工具庫集合。包含：ioc, exec(fork進程), graph(圖計算)等等常用工具集，并且完全零依賴。

Use

maven

<dependency>
  <groupId>com.github.harbby</groupId>
  <artifactId>gadtry</artifactId>
  <version>1.1.0</version>
</dependency>

gradle

compile group: 'com.github.harbby', name: 'gadtry', version: '1.0.0'

Ioc

Create Factory:

IocFactory iocFactory = IocFactory.create(binder -> {
    binder.bind(Set.class).by(HashSet.class).withSingle();
    binder.bind(HashSet.class).withSingle();
    binder.bind(List.class).byCreator(ArrayList::new);  //Single object
    binder.bind(Object.class, new Object());
    binder.bind(Map.class).byCreator(HashMap::new).withSingle();  //Single object
    binder.bind(TestInject.class);
});

Set a1 = iocFactory.getInstance(Set.class);
Set a2 = iocFactory.getInstance(Set.class);
Assert.assertEquals(true, a1 == a2); // Single object

Class Inject

public class TestInject
{
    @Autowired
    private TestInject test;

    @Autowired
    public TestInject(HashMap set){
        System.out.println(set);
    }
}

Exec New Jvm

Throw the task to the child process

JVMLauncher launcher = JVMLaunchers.newJvm()
    .setCallable(() -> {
        // this is child process
        System.out.println("************ runing your task ***************");
        return 1;
    })
    .addUserjars(Collections.emptyList())
    .setXms("16m")
    .setXmx("16m")
    .setConsole((msg) -> System.out.println(msg))
    .build();

VmFuture out = launcher.startAndGet();
Assert.assertEquals(out.get().get().intValue(), 1);
