I am looking into GWT elemental as a faster way to access the java dom in GWT. However when I look at the source code for the maven dependencies, all I see is js overlays. For instance:
public class JsNode extends JsElementalMixinBase implements Node {
protected JsNode() {}
public final native JsNamedNodeMap getAttributes() /*-{
return this.attributes;
}-*/;
public final native String getBaseURI() /*-{
return this.baseURI;
}-*/;
public final native JsNodeList getChildNodes() /*-{
return this.childNodes;
}-*/;
public final native JsNode getFirstChild() /*-{
return this.firstChild;
}-*/;
public final native JsNode getLastChild() /*-{
return this.lastChild;
}-*/;
....
This isn't too far off from what is in the default gwt xml dom. What am I missing here?
Thanks!
Elemental v1, which is no longer updated regularly, uses JSOs and JSNI, as that was the only option at the time.
Elemental v2 uses JsInterop, the new, future-proofed way of describing JS objects from within Java code. The sources (and issue tracking) is at https://github.com/google/elemental2/. You can find elemental2 in maven by searching for the groupId com.google.elemental2: http://search.maven.org/#search%7Cga%7C1%7Cg%3A%22com.google.elemental2%22
https://github.com/google/jsinterop-generator is the tool used to autogenerate elemental2, and can in theory be used on any other JS library to let GWT applications make use of it. I personally have not had a lot of luck getting it working, but the primary purpose of the tool is still to generate elemental2 sources, so this will continue improving as people use it.
