Interface PersistentStorageSystem

Allows data to be stored and retrieved between Lens sessions. In other words, data can be saved on device and loaded back in the next time the Lens is opened. Can be accessed with global.persistentStorageSystem.

See the Persistent Storage guide for more information.

Example

// Get the data store from PersistentStorageSystem
var store = global.persistentStorageSystem.store;

// Load score from previous Lens session. Defaults to 0 if data isn't found
var score = store.getFloat("totalScore");
print("loaded score: " + score);

function increaseScore() {
    // Increase score, then write it to the data store
    score += 1;
    store.putFloat("totalScore", score);
    print("new score: " + score);
}

// Increase score on tap event
script.createEvent("TapEvent").bind(increaseScore);
