Queue Controller

This controller handles the creation of download queues. This controller is used in every instance where a bulk number of files are required to be downloaded.

Functions

verifyInstallation (queue, isAssetDownload)

This function takes the following parameters:

• queue: Array with objects in the following format.
• isAssetDownload: Whether the queue contains assets.

Each item is checked against its SHA1 checksum and downloaded if it is missing or invalid. On Linux and macOS, .jar files and items marked isExecutable are made executable.

The function will return an empty array once every item has been verified. If an item cannot be downloaded, the function will reject with File Not Found: <origin>.
