RealmLess

Description

• Solutions to simplify Realm(ObjC) transactions.(简化Realm事务的解决方案)
• No beginWriteTransaction, no commitWriteTransaction,no __block.You can return method anywhere.Nested commit transactions will not throw exceptions.
• For developers who are not familiar with realm, using realmless can avoid many bugs.
• Give a star so god bless you.
• Swift Version

RealmLess transaction scope (RealmLess事务作用域)

• RealmLess transaction will be committed when leaving current scope.

  写事务将在离开当前作用域时自动提交.

• RealmLess variable rll_realm is provided in Realm-- scope to ensure the possibility of all operations.

  在Realm--作用域中提供了realm变量rll_realm来保证所有操作的可能性。

• In RealmLess scopes can be nested without throwing exceptions, and nested scopes will be merged. This solves a big trouble.

  在RealmLess作用域是可以被嵌套而不会抛出异常的，嵌套的作用域会被合并。这解决了一个很大烦恼。

Basic RealmLess scope (写作用域)

@realm_writing_scope
[rll_realm addObject:YourObject];

RealmLess Update scope (更新或添加作用域)

@realm_update_scope
[rll_realm addObject:YourObject];
RLLUpdate_obj = YourObject;

RealmLess Add scope (添加作用域)

@realm_add_scope
RLLAdd_obj = YourObject;

RealmLess Delete scope (删除作用域)

@realm_delete_scope
RLLDelete_obj = YourObject;

RealmLess transaction pool / 作用域池

• Commit pool definitions ensure commits transaction to default realm when leaving pool scope.The variable realm (default realm) can be used in the commit pool.
• 提交池确保了离开作用域时进行提交到default realm。在提交池内可以使用变量realm(default realm)。

Realm writing pool

@realm_writing_pool({
    [rll_realm addObject:YourObject];
});

RealmLess update pool

@realm_update_pool({
    ...
});

RealmLess add pool

@realm_add_pool({
    ...
});

RealmLess delete pool

@realm_delete_pool({
    ...
});

Switch realm variable (切换realm文件)

• Change realm variable of current scope.It will try to commit the previous transaction.

  在当前作用域内使用新的realm变量，这会将之前的事务提交。

@realm_writing_scope
...
@realm_switch(New Realm);
...

Nested / 嵌套

{ @realm_writing_scope
  (第一段事务 / First transaction)
  @realm_commit_up // The first transaction takes effect immediately so that the changes can be queried in the second transaction / 第一段事务立即生效从而可以在第二段事务中查询到变更
  (第二段事务 / Second transaction)
  @realm_commit_up
  (第三段事务 / Third transaction)
}


@realm_writing_pool({
    (第一段事务 / First transaction)
    @realm_commit_up // The first transaction takes effect immediately so that the changes can be queried in the second transaction / 第一段事务立即生效从而可以在第二段事务中查询到变更
    (第二段事务 / Second transaction)
});

Use RealmLess scoped objects / 使用RealmLess作用域对象

{
    RLLScopeObj(rll);
    [rll.realm addObject:obj];
    [rll nestedCommit];
    [rll.realm addObject:obj];
    [rll nestedCommit];
}
