example usage

...
* This event will be triggered when a child's sort order changes such that its
* position relative to its siblings changes. The `DataSnapshot` passed to the
* callback will be for the data of the child that has moved. It is also passed
* a second argument which is a string containing the key of the previous
* sibling child by sort order, or `null` if it is the first child.
*
* @example <caption>Handle a new value:</caption>
* ref.on('value', function(dataSnapshot) {
*   ...
* });
*
* @example <caption>Handle a new child:</caption>
* ref.on('child_added', function(childSnapshot, prevChildKey) {
*   ...

example usage

...
*
* This is equivalent to calling {@link firebase.database.Query#on `on()`}, and
* then calling {@link firebase.database.Query#off `off()`} inside the callback
* function. See {@link firebase.database.Query#on `on()`} for details on the
* event types.
*
* @example
* // Basic usage of .once() to read the data located at ref.
* ref.once('value')
*   .then(function(dataSnapshot) {
*     // handle read data.
*   });
*
* @param {string} eventType One of the following strings: "value",
*   "child_added", "child_changed", "child_removed", or "child_moved."
