net.liftweb.mapper.view.ItemsList

trait ItemsList

trait ItemsList[T <: Mapper[T]]


        

 extends
        ScalaObject

Keeps track of pending adds to and removes from a list of mappers. Supports in-memory sorting by a field. Usage: override metaMapper with a MetaMapper instance, call sortBy to specify the field to sort by. If it is already sorted by that field it will sort descending, otherwise ascending. Call save to actualize changes.

Fields

added..

var added

The list of items pending to be added to the database

List[T]

ascending..

var ascending

The sort direction

Boolean

current..

var current

The list of items that correspond to items in the database

List[T]

items..

def items

Returns the items (current + added - removed), sorted [details]

Sorting sorts strings case-insensitive, as well as Ordered and java.lang.Comparable. Anything else where both values are nonnull are sorted via their toString method (case sensitive)

Seq[T]

metaMapper..

abstract def metaMapper

The MetaMapper that provides create and findAll functionality etc [details]

Must itself be a T (the mapper type it represents)

T with MetaMapper[T]

removed..

var removed

The list of items to be deleted from current

List[T]

sortField..

var sortField

The field to sort by, if any

Option[MappedField[Any, T]]

sortNullFirst..

var sortNullFirst

Whether the sorting algorithm should put null first or last

Boolean
