Examples with JsObject elemental2.core.JsObject used on opensource projects

Example 1 with JsObject

use of elemental2.core.JsObject in project vue-gwt by Axellience.

the class VueGWTTools method extendVueConstructorWithJavaPrototype.

/**
 * Copy a Java class prototype to a VueComponent declaration. This allows
 * VueComponent created by Vue to pass as an instance of the VueComponent
 * class they implement.
 * @param extendedVueJsConstructor The Vue.js constructor function to extend
 * @param componentJavaPrototype The VueComponent class JS prototype to
 * extend with
 * @param <T> The type of the VueComponent
 */
public static <T extends VueComponent> void extendVueConstructorWithJavaPrototype(VueJsConstructor<T> extendedVueJsConstructor, ComponentJavaPrototype<T> componentJavaPrototype) {
    JsPropertyMap vueProto = (JsPropertyMap) ((JsPropertyMap) extendedVueJsConstructor).get("prototype");
    JsObject vueProtoJsObject = ((JsObject) vueProto);
    componentJavaPrototype.forEach(protoProp -> {
        if (!vueProtoJsObject.hasOwnProperty(protoProp))
            vueProto.set(protoProp, componentJavaPrototype.get(protoProp));
    });
}

Example 2 with JsObject

use of elemental2.core.JsObject in project vue-gwt by Axellience.

the class VueGWTObserverManager method initClassPropertiesCache.

private Map<String, Object> initClassPropertiesCache(JsObject object, String className) {
    final Map<String, Object> tmpCache = new HashMap<>();
    classesPropertyCaches.put(className, tmpCache);
    JsPropertyMap prototype = (JsPropertyMap) object.__proto__;

            tmpCache.put(property, value);
        }
    });
    return tmpCache;
}

Example 3 with JsObject

use of elemental2.core.JsObject in project vue-gwt by Axellience.

the class VueGWTObserverManager method makeStaticallyInitializedPropertiesReactive.

/**
 * Due to GWT optimizations, properties on java object defined like this are not observable in
 * Vue.js when not running in dev mode:
 * <br>
 * private String myText = "Default text";
 * private int myInt = 0;
 * <br>
 * This is because GWT define the default value on the prototype and don't define it on the
 * object.
 * Therefore Vue.js don't see those properties when initializing it's observer.
 * To fix the issue, we manually look for those properties and set them explicitly on the
 * object.
 * @param object The Java object to observe
 * @param className The Java class name to observe
