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);
 
}
