Introduction

For maximum efficiency, GWT compiles your Java source into a monolithic script. Now gwt-ent provide a reflection implement by gwt code generator mechanism.

This Framework support

1. Class http://code.google.com/p/gwt-ent/source/browse/trunk/gwtent/src/main/java/com/gwtent/reflection/client/ClassType.java
2. Field http://code.google.com/p/gwt-ent/source/browse/trunk/gwtent/src/main/java/com/gwtent/reflection/client/Field.java
3. Method http://code.google.com/p/gwt-ent/source/browse/trunk/gwtent/src/main/java/com/gwtent/reflection/client/Method.java
4. Constructor http://code.google.com/p/gwt-ent/source/browse/trunk/gwtent/src/main/java/com/gwtent/reflection/client/Constructor.java
5. Metedata http://code.google.com/p/gwt-ent/source/browse/trunk/gwtent/src/main/java/com/gwtent/reflection/client/HasMetaData.java
6. Annotation http://code.google.com/p/gwt-ent/source/browse/trunk/gwtent/src/main/java/com/gwtent/reflection/client/HasAnnotations.java

How to use

# add Annotation Or Reflection Marker interface into your pojo class

@Reflectable 
public class TestReflection{ 
} 
 
public class TestReflection implements Reflection{ 
} 
 
@Reflect_Domain 
public class TestReflection{ 
}

# get ClassType.

ClassType classType = TypeOracle.Instance.getClassType(TestReflection.class);

For example:

public void testReflection(){ 
    TestReflection test = new TestReflection(); 
    ClassType classType = TypeOracle.Instance.getClassType(TestReflection.class); 
     
    test.setString("set by code"); 
    System.out.println("after SetByCode:" + test.getString()); 
    System.out.println("after SetByCode:" + classType.invoke(test, "getString", null)); 
     
    classType.invoke(test, "setString", new Object[]{"set by invoke"}); 
    System.out.println("after SetByInvoke:" + classType.invoke(test, "getString", null)); 
  } 
}

The output is :

after SetByCode:set by code 
after SetByCode:set by code 
after SetByInvoke:set by invoke

Control you javascript size

GWTENT provide you more power to control how much reflection information created.

The Class Scope

You can control whether have:

1. Class Annotation
2. Fields
3. Methods
4. Constructors
5. Field and Method Annotations
6. Relation Types(The field type, the return type of method, the type of Parameters)
7. Super Classes ( all the super classes of this class will generate reflection information)
8. Assignable Classes (all assignable classes. if annotate to a class, this is mean All subClasses will generate reflection information; if annotate to a interface, then all implement classes will generate reflection information; if annotate to an annotation, then all types annotated by this annotation will generate reflection information)

The Field/Method Scope

1. Annotations
2. Field Type
3. Method Return Type
4. Method Parameter Type
