7 | Documentation is embarrassingly out of date...
8 |
9 | Best place may be the Javadoc (has compiled examples in it)
10 | http://timyates.github.io/groovy-stream/javadoc/index.html?groovy/stream/Stream.html
11 |
12 | Out of date usage, news, etc. can be found here: http://timyates.github.com/groovy-stream/ or http://timyates.github.com/groovy-stream/main.html
13 |
14 | The first casualty of lack-of-time is documentation :-(

9 | Map functions transform elements in the Stream from one form to another.
10 |
11 | At it's simplest level, it looks like the following:
12 |
13 | [source,groovy]
14 | ----
15 | include::../../src/test/groovy/asciidoc/MapExamples.groovy[tags=simple_example,indent=0]
16 | ----
17 |
18 | You can also pass the index into the map call by calling `mapWithIndex`:
19 |
20 | [source,groovy]
21 | ----
22 | include::../../src/test/groovy/asciidoc/MapExamples.groovy[tags=index_example,indent=0]
23 | ----
24 |
25 | There also exists a `flatMap` variant, so you can return a Collection of values and
26 | each of these will be iterated first, before the underlying Stream is queried again for
27 | the next sequence in the list:
28 |
29 | [source,groovy]
30 | ----
31 | include::../../src/test/groovy/asciidoc/MapExamples.groovy[tags=flat_example,indent=0]
32 | ----
33 |
34 | And of course, this has a `flatMapWithIndex` variant.
35 |
36 | [source,groovy]
37 | ----
38 | include::../../src/test/groovy/asciidoc/MapExamples.groovy[tags=flat_index_example,indent=0]
