protected hideThreshold_ :Number

menu/menu-button.js, line 104

Hide the menu if the number of items is less than or equal to this threshold. This defaults to 0 and whenever we add items which can be hidden to the menu we'll increment it. We list it here because every time we run createMenu we need to reset the value.

enableTouchActivity()

component.js, line 1173

This function reports user activity whenever touch events happen. This can get turned off by any sub-components that wants touch events to act another way.

Report user touch activity when touch events occur. User activity gets used to determine when controls should show/hide. It is simple when it comes to mouse events, because any mouse event should show the controls. So we capture mouse events that bubble up to the player and report activity when that happens. With touch events it isn't as easy as touchstart and touchend toggle player controls. So touch events can't help us at the player level either.

User activity gets checked asynchronously. So what could happen is a tap event on the video turns the controls off. Then the touchend event bubbles up to the player. Which, if it reported user activity, would turn the controls right back on. We also don't want to completely block touch events from bubbling up. Furthermore a touchmove event and anything other than a tap, should not turn controls back on.

• Component#event:touchstart
• Component#event:touchmove
• Component#event:touchend
• Component#event:touchcancel

localize(string, tokensopt, defaultValueopt) → {string}

component.js, line 254

Localize a string given the string in english.

If tokens are provided, it'll try and run a simple token replacement on the provided string. The tokens it loooks for look like {1} with the index being 1-indexed into the tokens array.

If a defaultValue is provided, it'll use that over string, if a value isn't found in provided language files. This is useful if you want to have a descriptive key for token replacement but have a succinct localized string and not require en.json to be included.

Currently, it is used for the progress bar timing.

{
  "progress bar timing: currentTime={1} duration={2}": "{1} of {2}"
}

It is then used like so:

this.localize('progress bar timing: currentTime={1} duration{2}',
              [this.player_.currentTime(), this.player_.duration()],
              '{1} of {2}');

Which outputs something like: 01:23 of 24:56.

Parameters:

Name	Type	Attributes	Description
string	string		The string to localize and the key to lookup in the language files.
tokens	Array.<string>	<optional>	If the current item has token replacements, provide the tokens here.
defaultValue	string	<optional>	Defaults to string. Can be a default value to use for token replacement if the lookup key is needed to be separate.
