Iterator<T>

public class System.Iterator<T> : System.Any

The values of a function with yield, made one at a time: each Next() runs the function on to its next yield. loop (T x in F()) walks them. An iterator runs once (call the function again to start over).

Any Iterator<T>

Properties

property Current: T
#

read-only

The value Next() moved to.

Methods

method Next() -> bool
#

abstract

Runs on to the next value: false when the function has ended (and from then on).

method Dispose() -> void
#

Ends the iterator before its last value: the finally blocks around the yield it paused at run (as they do when it ends on its own), and Next() gives false from then on. Nothing happens to one that has ended.

method Iterator() -> System.Iterator<T>
#

Itself: loop (T x in iterator) walks what is left of it.

Fields

field current: T
#

inherited

The value the last yield gave.

field disposing: bool
#

inherited

Set by Dispose(): the next step runs the finally blocks around the last yield and ends.
