Requesting and Getting Revisions

The API offers methods to request revisions and to get those requested revisions once they have been retrieved.

Requesting and Getting Revisions

Request the revisions for a given document comparison. Revisions requests complete asynchronously. A PCCViewer.RevisionsRequest will be returned that provides events for revisions retrieval progress and members to access retrieved revisions:

Example	Copy Code
// Request revisions var revisionsRequest = viewerControl.requestRevisions(); // Subscribe to the PartialRevisionsAvailable event to get revisions as they become available revisionsRequest.on('PartialRevisionsAvailable', function(_event) { // Get the newly available revisions var newRevisions = _event.partialRevisions; }); // Subscribe to the RevisionsRetrievalCompleted event to get revisions when all of them are available revisionsRequest.on("RevisionsRetrievalCompleted", function(){ // Get all of the revisions for that comparison var revisions = revisionsRequest.getRevisions(); });

Example

Copy Code

// Request revisions
var revisionsRequest = viewerControl.requestRevisions(); 
// Subscribe to the PartialRevisionsAvailable event to get revisions as they become 
available
revisionsRequest.on('PartialRevisionsAvailable', function(_event) { 
    // Get the newly available revisions
    var newRevisions = _event.partialRevisions; 
});
// Subscribe to the RevisionsRetrievalCompleted event to get revisions when 
all of them are available
revisionsRequest.on("RevisionsRetrievalCompleted", function(){ 
    // Get all of the revisions for that comparison
    var revisions = revisionsRequest.getRevisions();
});
