Class Streams

java.lang.Object

de.digitalcollections.solrocr.util.Streams

public class Streams
extends Object

Stream helpers. Only needed for `zip` and `stream(Iterator)`, since Lucene/Solr ships with an ancient version of Guava that does not yet have `Streams.zip` and `Streams.stream`. This is, however, going to be resolved with 8.0, so this class is only here temporarily.
