Announcement

Curson

Cursor binding which uses annotation processing to generate boilerplate code for you.

  • Eliminate getColumnIndex calls by using @CursorRow on fields.

How to use

Create Entity class

You have to create a entity class like below.

class Item {
    @CursorRow("_id"/*CURSOR_COLUMN_NAME*/)
    int id;
    @CursorRow("MEMO")
    String memo;
    @CursorRow("DATE")
    long date;
}

CursorRow annotations supports

  • byte[]
  • int / Integer
  • double / Double
  • float / Float
  • short / Short
  • String

Convert to entity/cursor

To Entity

public Item getItem() {
    Cursor cursor = context.getContentResolver().query(
            ExContentProvider.Contract.MEMO_URI,
            null,
            MemoColumns.MEMO_ID + " = ?",
            new String[]{dataSnapshot.getKey()}, null);
    return Curson.fromCursor(cursor, Item.class, 0);
}

public List<Item> getItems() {
    Cursor cursor = context.getContentResolver().query(
            ExContentProvider.Contract.MEMO_URI,
            null, null, null, null);
    return Curson.fromCursor(cursor, Item.class);
}

To Cursor

public Cursor toCursor() {
    Item item = new Item();
    item.id = 1;
    item.memo = "Hello Curson!!";
    item.date = 1L;
    return Curson.toCursor(item, Item.class);
}

public Cursor toCursor() {
    List<Item> items = new ArrayList<>();
    Item item = new Item();
    item.id = 1;
    item.memo = "Hello Curson!!";
    item.date = 1L;
    items.add(item);
    return Curson.toCursor(items, Item.class);
}
