Filter tuples within your channel based on item values

Let's say you have a channel with tuples that are simply multiple items and you want to remove every tuple whose any of the items is null. The code below does that for you, but even if it wasn't a string, substring or anything else, the code would still be very similar to the one shown below.

Channel
  .of(
    [file('/a/example/path/file'), null, 'a', 1, true],
    [file('/a/example/path/file'), 100, 'a', 1, null],
    [file('/a/example/path/file'), 100, 'a', 1, false],
    [file('/a/example/path/file'), null, 'a', 1, true],
    [file('/a/example/path/file'), 100, 'a', 1, true]
  )
  .filter { !it.contains(null) }
  .view()

Running the snippet above should show the following output:
