// About: Examples
//
// These working examples, complete with fully commented code, illustrate a few
// ways in which this plugin can be used.
//
// Debouncing - http://benalman.com/code/projects/jquery-dotimeout/examples/debouncing/
// Delays, Polling - http://benalman.com/code/projects/jquery-dotimeout/examples/delay-poll/
// Hover Intent - http://benalman.com/code/projects/jquery-dotimeout/examples/hoverintent/
//
// About: Support and Testing
//
// Information about what version or versions of jQuery this plugin has been
// tested with, what browsers it has been tested in, and where the unit tests
// reside (so you can test it yourself).
//
// jQuery Versions - 1.3.2, 1.4.2
// Browsers Tested - Internet Explorer 6-8, Firefox 2-3.6, Safari 3-4, Chrome 4-5, Opera 9.6-10.1.
// Unit Tests - http://benalman.com/code/projects/jquery-dotimeout/unit/
//
// About: Release History
//
// 1.0 - (3/3/2010) Callback can now be a string, in which case it will call
// the appropriate $.method or $.fn.method, depending on where .doTimeout
// was called. Callback must now return `true` (not just a truthy value)
// to poll.
// 0.4 - (7/15/2009) Made the "id" argument optional, some other minor tweaks
// 0.3 - (6/25/2009) Initial release

'$:nomunge'; // Used by YUI compressor.

// Reused internal string.
doTimeout = 'doTimeout',
// A convenient shortcut.
aps = Array.prototype.slice;
// Method: jQuery.doTimeout
//
// Initialize, cancel, or force execution of a callback after a delay.
//
// If delay and callback are specified, a doTimeout is initialized. The
// callback will execute, asynchronously, after the delay. If an id is
// specified, this doTimeout will override and cancel any existing doTimeout
// with the same id. Any additional arguments will be passed into callback
// when it is executed.
//
// If the callback returns true, the doTimeout loop will execute again, after
// the delay, creating a polling loop until the callback returns a non-true
// value.
//
// Note that if an id is not passed as the first argument, this doTimeout will
// NOT be able to be manually canceled or forced. (for debouncing, be sure to
// specify an id).
//
// If id is specified, but delay and callback are not, the doTimeout will be
// canceled without executing the callback. If force_mode is specified, the
// callback will be executed, synchronously, but will only be allowed to
// continue a polling loop if force_mode is true (provided the callback
// returns true, of course). If force_mode is false, no polling loop will
// continue, even if the callback returns true.
//
// Usage:
//
// > jQuery.doTimeout( [ id, ] delay, callback [, arg ... ] );
// > jQuery.doTimeout( id [, force_mode ] );
//
// Arguments:
//
// id - (String) An optional unique identifier for this doTimeout. If id is
// not specified, the doTimeout will NOT be able to be manually canceled or
// forced.
// delay - (Number) A zero-or-greater delay in milliseconds after which
// callback will be executed.
// callback - (Function) A function to be executed after delay milliseconds.

// If omitted, cancel that id's doTimeout.

// Method: jQuery.fn.doTimeout
//
// Initialize, cancel, or force execution of a callback after a delay.
// Operates like <jQuery.doTimeout>, but the passed callback executes in the
// context of the jQuery collection of elements, and the id is stored as data
// on the first element in that collection.
//
// If delay and callback are specified, a doTimeout is initialized. The
// callback will execute, asynchronously, after the delay. If an id is
// specified, this doTimeout will override and cancel any existing doTimeout
// with the same id. Any additional arguments will be passed into callback
// when it is executed.
//
// If the callback returns true, the doTimeout loop will execute again, after
// the delay, creating a polling loop until the callback returns a non-true
// value.
//
// Note that if an id is not passed as the first argument, this doTimeout will
// NOT be able to be manually canceled or forced (for debouncing, be sure to
// specify an id).
//
// If id is specified, but delay and callback are not, the doTimeout will be
// canceled without executing the callback. If force_mode is specified, the
// callback will be executed, synchronously, but will only be allowed to
// continue a polling loop if force_mode is true (provided the callback
// returns true, of course). If force_mode is false, no polling loop will
// continue, even if the callback returns true.
//
// Usage:
//
// > jQuery('selector').doTimeout( [ id, ] delay, callback [, arg ... ] );
// > jQuery('selector').doTimeout( id [, force_mode ] );
//
// Arguments:
//
// id - (String) An optional unique identifier for this doTimeout, stored as
// jQuery data on the element. If id is not specified, the doTimeout will
// NOT be able to be manually canceled or forced.
// delay - (Number) A zero-or-greater delay in milliseconds after which
// callback will be executed.
// callback - (Function) A function to be executed after delay milliseconds.
// callback - (String) A jQuery.fn method to be executed after delay
// milliseconds. This method will only poll if it explicitly returns
// true (most jQuery.fn methods return a jQuery object, and not `true`,
// which allows them to be chained and prevents polling).
// force_mode - (Boolean) If true, execute that id's doTimeout callback
// immediately and synchronously, continuing any callback return-true
// polling loop. If false, execute the callback immediately and
// synchronously but do NOT continue a callback return-true polling loop.
// If omitted, cancel that id's doTimeout.
//
// Returns:
//
// When creating a <jQuery.fn.doTimeout>, the initial jQuery collection of
// elements is returned. Otherwise, if force_mode is true, false or undefined
// and there is a yet-to-be-executed callback to cancel, true is returned,
// but if no callback remains to be executed, undefined is returned.
