Build Identifier: currently it is not possible to call e.g. filter on an Iterator. However eAllContents returns a TreeIterator Reproducible: Always
This is what the /org.eclipse.xtext.xtend2.lib/src/org/eclipse/xtext/xtend2/lib/EObjectExtensions.java /org.eclipse.xtext.xtend2.lib/src/org/eclipse/xtext/xtend2/lib/ResourceExtensions.java /org.eclipse.xtext.xtend2.lib/src/org/eclipse/xtext/xtend2/lib/ResourceSetExtensions.java extensions are for. You have to explicitely import them as static extensions, as we don't want to force Xtend users to have a dependency on EMF.
We introduce an IteratorIterable for this public class IteratorIterable<T> implements Iterable<T> { private Iterator<T> iterator; @Override public Iterator<T> iterator() { return iterator; } public IteratorIterable(Iterator<T> iterator) { super(); this.iterator = iterator; } public static <T> IteratorIterable<T> iterable(Iterator<T> i) { return new IteratorIterable<T>(i); } } resource.allContents.iterable.filter(typeof(Greeting))
We should consider to have something like IteratorExtensions. Furthermore it may be interesting to allow iterators in for loops, e.g. for(something: somethingElse.eAllContents) { .. }
similar to the things that are available in IterableExtensions or Iterators + Iterator.asIterable instead of for(e: iterator)
I've pushed IteratorExtensions and it includes one extension so far: public static <T> Iterable<T> toIterable(final Iterator<T> iterator)
Closing all bugs that were set to RESOLVED before Neon.0
