Class DataStorage

Method Details

• readAllPackages

  public static ArrayList<DataPackage> readAllPackages(Context context)

• printPackages

  public static void printPackages(Context context, ArrayList<DataPackage> dataPackages)

• readDataPackage

  public static DataPackage readDataPackage(Context context, int id)

  Retrieves a single data package from storage by its ID. This is the core read method used by all typed getter methods (getInt, getLong, etc.). The method queries the database using the ContentResolver, retrieves the cursor, and converts the first matching row into a DataPackage object.

  Parameters:

  context - the application context

  id - the storage ID constant identifying which data to retrieve

  Returns:

  the DataPackage containing the stored value, or null if not found

• clear

  public static void clear(Context context)

• setBlob

  public static void setBlob(Context context, int id, byte[] value)

• getBlob

  public static byte[] getBlob(Context context, int id, byte[] defaultValue)

• setFloat

  public static void setFloat(Context context, int id, float value)

• getFloat

  public static float getFloat(Context context, int id, float defaultValue)

• setInt

  public static void setInt(Context context, int id, int value)

• getInt

  public static int getInt(Context context, int id, int defaultValue)

• setLong

  public static void setLong(Context context, int id, long value)

• getLong

  public static long getLong(Context context, int id, long defaultValue)

• setString

  public static void setString(Context context, int id, String value)

• getString

  public static String getString(Context context, int id, String defaultValue)

• setBoolean

  public static void setBoolean(Context context, int id, boolean value)

• getBoolean

  public static boolean getBoolean(Context context, int id, boolean defaultValue)

  Retrieves a boolean value from storage. Note: Boolean values are stored as long (0 for false, non-zero for true).

  Parameters:

  context - the application context

  id - the storage ID constant

  defaultValue - the default value to return if no data exists

  Returns:

  the stored boolean value, or defaultValue if not found

• setStation

  public static void setStation(Context context, Weather.WeatherLocation weatherLocation)

  Stores the currently selected weather station location in persistent storage. The location is serialized to a string format before storage.

  Parameters:

  context - the application context

  weatherLocation - the weather station location to store

• getSetStationLocation

  public static Weather.WeatherLocation getSetStationLocation(Context context)

  Retrieves the currently selected weather station location from storage. If no station has been set, this method initializes storage with the default station and returns that default location. This is a "get-or-set" pattern: it guarantees a valid weather location is always returned by creating and storing a default if none exists.

  Parameters:

  context - the application context

  Returns:

  the stored weather location, or the default location if none was previously set
