Returns a promise that is fulfilled when all of the input promises are fulfilled. The returned promise is fulfilled with an array of the fulfilment values for all of the input promises.

If any of the promises are rejected, then the returned promise will be rejected with the reason of that rejected promise. If rejected, there will be guarantee of the state all promises in the promises array, some have been resolved and some may still be pending.

Example

var viewerControl = $("#myElement").pccViewer(...).viewerControl;

// Get page text for specific pages
PCCViewer.Promise.all([
    viewerControl.requestPageText(1),
    viewerControl.requestPageText(2)]).then(
    function onFulfilled(values) {
       // Values is an array that contains the text of pages 1 & 2.
       var page1Text = values[0];
       var page2Text = values[1];
    },
    function onRejected(error) {
        alert("Something went wrong getting the page text. " + (error.message ? error.message : error));
    }
);

// Get attributes for all pages
var allPages = _.range(1, viewerControl.getPageCount() + 1); // Using Underscore.js - generates an array like [1, 2, ..., 12]
var pageAttributePromises = _.map(allPages, viewerControl.requestPageAttributes, viewerControl); // Using Underscore.js
PCCViewer.Promise.all(pageAttributePromises).then(
    function onFulfilled(allPageAttributes) {
        console.log(JSON.stringify(allPageAttributes));
    },
    function onRejected(error) {
        alert("Something went wrong getting the page attributes. " + (error.message ? error.message : error));
    }
);

// it's OK to pass a value that is not a promise
PCCViewer.Promise.all([
    viewerControl.requestPageAttributes(1),
    true]).then(
    function(values) {
       // Values is an array that contains the text of pages 1 and the value `true`.
       var page1Text = values[0]; // text of page 1
       var otherValue = values[1]; // true
    }
);

Use .then(...) to register callbacks to access the current or eventual value, or reason, of the promise.

A promise is in one of three states: pending, resolved, rejected. The onFulfilled callback will be called when a promise is resolved, or if a promise is already resolved, then the onFulfilled callback will be called immediately. The onRejected callback will be called when a promise is rejected, or if a promise is already rejected, then the onRejected callback will be called immediately.

Example

var viewerControl = $("#myElement").pccViewer(...).viewerControl;

// a basic example
viewerControl.requestPageText(1).then(
    function onFulfilled(value) {
       // according to the definition of requestPageText, the promise will be resolved with the text
       // of the page.
       var pageText = value;
    },
    function onRejected(error) {
        // according to the definition of requestPageText, the promise will be rejected if there is
        // an error extracting text for the document.
        alert("Something went wrong getting the text of page 1. " + (error.message ? error.message : error));
    }
);

// it's OK to pass a value of null (or undefined) for `onFulfilled`
viewerControl.requestPageText(1).then(
    null,
    function onRejected(error) { ... }
);

// it's OK to ignore the onRejected parameter, or pass null or undefined
viewerControl.requestPageText(1).then(
    function onFulfilled(value) { ... }
);

An onFulfilled callback is called if or when a PCCViewer.Promise is resolved.

An onRejected callback is called if or when a PCCViewer.Promise is rejected.
