Collection.ObservableMutable

Alias for addAll

Generally Opt could be added as a stream.

This overload is sligtly more efficient, but it is also required for mapped Opt expressions, where Opt type is harder to resolve and it would not compile.

Alias for addAll

Calls addAll and returns container

 // Generic example
 val x =  Idx.M(1, 2, 3)

 x ++= (4 <> 6) ++= Stream(7, 8, 9)

 x.stream.tp // Stream(1, 2, 3, 4, 5, 6, 7, 8, 9)

Alias for add

Calls add and returns container

 // Generic example
 val x =  Idx.M(1, 2, 3)

  x += 4 += 5 += 6

  x.stream.tp // Prints Stream(1, 2, 3, 4, 5, 6)

Alias for removeAll

Removes all collection elements, which are equal to those in given stream

Returns the collection itself

Alias for remove

Removes all collection elements, which are equal to the given value

Returns the collection itself

Add

Adds given value to target container

 // Generic example
 val x =  Idx.M(1, 2, 3)

  x.add(4)
  x.add(5)
  x.add(6)

  x.stream.tp // Prints Stream(1, 2, 3, 4, 5, 6)

Add many

Adds given stream of elements to target container

 // Generic example
 val x =  Idx.M(1, 2, 3)

  x.addAll(4 <> 6)
  x.addAll( Stream(7,8,9))

  x.stream.tp // Stream(1, 2, 3, 4, 5, 6, 7, 8, 9)

Remove everything

Discards all elements, so the colection size will become 0

On element add

Subscribes given function to element add event

val co: Collection.ObservableMutable[Int] = Collection.OM[Int]()

co.onAdd("Added: "+ _ tp())

co ++= 1 <> 3

// Output
Added: 1
Added: 2
Added: 3

On element remove

Subscribes given function to element remove event

val co: Collection.ObservableMutable[Int] = Collection.OM[Int]()

co.onRemove("Removed: "+ _ tp())

co ++= 1 <> 10

co --= 5 <> 7

// Output
Removed: 7
Removed: 6
Removed: 5

Remove element

Removes all collection elements, which are equal to the given value

Returns count of removed elements, which can be 0, 1, or many

Remove all streamed

Removes all collection elements, which are equal to those in given stream

Returns count of removed elements, which can be 0, 1, or many

Replace everything

Discards all old elements and adds all provided elements

Stream elements

Returns a stream of all collection elements

Unless specifically defined, the order must be assumed as random

  val c = Collection(1,3,5,7)
  c.stream.tp

  // Output
  Stream(1, 3, 5, 7)
