Java List and array access improvements #561
Conversation
both NativeJavaArray and NativeJavaList for better compatability with JS. Add a couple of tests for the list and array access.

Thanks. I'll take a look at this next week after we finish the 1.7.11 release. One difference between this and other built-in classes is in the way that it adds new methods -- other native classes inherit from IdScriptableObject whereas this one uses a different method. One thing that we might want to do is to make this class work that way too. Also, a number of the prototype classes on regular arrays should work on Java arrays too -- we should look and see why not. |

Yeah, I tried to use a couple of ways to implement the JavaScript functions. The thing is, that the wrapped object should expose all the methods and properties from the object implementing the List interface. For example, in our projects we tend to have business objects, which implement List interface, but have quite a lot of other business logic in them too. |

Is there a test when start is specified as an argument?
var a = java.util.Arrays.asList(1, 2, 3).toArray();
a.indexOf(1, 5); // -1?
a.indexOf(1, -5); // throw error?|

Is there a test to make sure deepEquals is called?

This test is passing in the current codebase.

| if (id.equals("length")) | ||
| return Integer.valueOf(list.size()); | ||
| else if (id.equals("includes")) |

This is only one extension of the list.
I think we were both trying to reach the same goal: See #830
A JavaList should be treated like an Array and provide functions like join, includes etc...

Most of the test cases SHOULD¹ pass in the current codebase of #1083. (¹ plugins.gradle.com is currently down...) |
Add a new wrapper calss NativeJavaList that provides natural JS array access for Java lists. Improve NativeJavaArray for better compatability with JS via the addition of indexOf and includes functions. Add a couple of tests for the list and array access.
