getRange method
Iterable<E> getRange(Returns an Iterable
that iterates over the objects in the range start
inclusive to end
exclusive.
The provide range, given by start
and end
, must be valid at the time of the call.
A range from start
to end
is valid if 0 <= start <= end <= len
, where len
is this list's length
. The range starts at start
and has length end - start
. An empty range (with end == start
) is valid.
The returned Iterable
behaves like skip(start).take(end - start)
. That is, it does not throw if this list changes size.
List<String> colors = ['red', 'green', 'blue', 'orange', 'pink']; Iterable<String> range = colors.getRange(1, 4); range.join(', '); // 'green, blue, orange' colors.length = 3; range.join(', '); // 'green, blue'
