tarunon / barrel Goto Github PK

These methods are not works
Aggregate::groupBy(keyPath: (T) -> U) -> Group
Group::groupBy(keyPath: (T) -> U) -> Group

I'll make organization of Barrel (or rename?).
And separate CoreData and Realm support library.

That sounds refreshObject bad solution...

e.g.)

context.fetch(Person).filter{ $0 == person }.execute().all()

Cannot use this workaround no longer.
Needs to update every types.

protocol A { associatedtype B }
class C: A { typealias B = C }
extension A where Self: C { typealias B = Self }

For example, a Person class has property name, age.
And a Staff class extends Person, and use Staff type in attribute.
e.g.)

context.fetch(Staff).filter{ $0.age > 20 }.execute()

This code crash in execute() state, caused filter() parameter.

Think the Person model.

class Person: NSManagedObject {
    @NSManaged var name: String
    @NSManaged var age: NSNumber
    @NSManaged var parent: Person
    @NSManaged var children: Set<Person>
}

In this case, you can evaluate value in closure type name, age, or parent.
If you evaluate children value in closure, unfortunately, Barrel will be crashed.
This issues caused PropertyAttributeCoder protocol supported only String type.

e.g.)

context.fetch().orderBy{ $1.age < $0.age }

in orderBy closure case $1 before than $0

Because of attribute and completion object created at same context.

e.g.)

class Note: NSManagedObject {
    @NSManaged public var title: String
    @NSManaged public var created: NSDate
    @NSManaged public var content: String?
}

In this case, Barrel crash when evaluate content in closure.

context.fetch(Note).filter{ $0.content == nil }.execute()

Because created is Optional property.
Type of created be hound Optional, And in Expression.init or SortDescriptor.init argument type is also Optional...
It is necessary to unwrap Optional in Expression.init() and SortDescriptor.init().

brl_ prefix is not match Swift3 coding style.
use brl. instead of brl_.

It is taking too time in this line.
