final class PhutilExampleBufferedIterator
libphutil Technical Documentation (Core Utilities)

Example implementation and test case for PhutilBufferedIterator.

Tasks

Methods to Implement

Configuration

  • final public function getPageSize() — Get the configured page size.
  • final public function setPageSize($size) — Configure the page size. Note that implementations may ignore this.

Iterator Implementation

  • final public function rewind()
  • final public function valid()
  • final public function current()
  • public function key() — By default, the iterator assigns a "natural" key (0, 1, 2, ...) to each result. This method is intentionally nonfinal so you can substitute a different behavior by overriding it if you prefer.
  • final public function next()

Other Methods

Methods

protected function loadPage()

PhutilBufferedIterator

Called when the iterator needs a page of results. You should load the next result page and update your internal cursor to point past it.

If possible, you should use getPageSize() to choose a page size.
