示例1: _removeItem
/**
* delete item from cache
* @private
* @param prefixedKey - the key of the item
* @param size - optional, the byte size of the item
*/
async _removeItem(prefixedKey, size?) {
const itemSize = size? size : (JSON.parse(await AsyncStorage.getItem(prefixedKey))).byteSize;
// first try to update the current size of the cache
await this._decreaseCurSizeInBytes(itemSize);
// try to remove the item from cache
try {
await AsyncStorage.removeItem(prefixedKey);
} catch (removeItemError) {
// if some error happened, we need to rollback the current size
await this._increaseCurSizeInBytes(itemSize);
logger.error(`Failed to remove item: ${removeItemError}`);
}
}示例2: clear
/**
* clear the entire cache
* The cache will abort output a warning:
* If error happened with AsyncStorage
* @return {Promise}
*/
async clear() {
logger.debug(`Clear Cache`);
try {
const keys = await AsyncStorage.getAllKeys();
const keysToRemove = [];
for (let i = 0; i < keys.length; i += 1) {
if (keys[i].indexOf(this.config.keyPrefix) === 0) {
keysToRemove.push(keys[i]);
}
}
// can be improved
for (let i = 0; i < keysToRemove.length; i += 1) {
await AsyncStorage.removeItem(keysToRemove[i]);
}
} catch (e) {
logger.warn(`clear failed! ${e}`);
}
}示例3: remove
static remove(key) {
return AsyncStorage.removeItem(key)
}
