Idx.Mutable

Alias for addAllAt

Adds stream elements at given position

  // Generic example
  val x = ('A' <> 'F').~.toBuffer

  x ++=@ (4, 'e' <> 'g') ++=@ (1, ~~('b','c','d'))

  x.~.tp // Prints ~(A, b, c, d, B, C, D, e, f, g, E, F)

Alias for addAt

Adds element at given position

  // Generic example
  val x = ('A' <> 'F').~.toBuffer

  x +=@ (3, 'd') +=@ (2, 'c') +=@ (1, 'b') +=@ (0, 'a')

  x.~.tp // Prints ~(a, A, b, B, c, C, d, D, E, F)

Append element

Adds given element to the end of this Idx

Append all

Adds all stream values to the end of this Idx

Add stream at position

Adds stream elements at given position

  // Generic example
  val x = ('A' <> 'F').~.toBuffer

  x.addAllAt(4, 'e' <> 'g')
  x.addAllAt(1, ~~('b','c','d'))

  x.~.tp // Prints ~(A, b, c, d, B, C, D, e, f, g, E, F)

Add at position

Adds element at given position

  // Generic example
  val x = ('A' <> 'F').~.toBuffer

  x.addAt(3, 'd')
  x.addAt(2, 'c')
  x.addAt(1, 'b')
  x.addAt(0, 'a')

  x.~.tp // Prints ~(a, A, b, B, c, C, d, D, E, F)

Remove element

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

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

Remove range

Removes elements at given range

 // Generic example
 val x = (0 <> 10).~.toBuffer

 x.remove(7 <> 8)
 x.remove(2 <> 4)

 x.~.tp // Prints ~(0, 1, 5, 6, 9, 10)

Remove at position

Removes element at given position

 // Generic example
 val x = ('A' <> 'D').~.toBuffer

 x.remove(2)
 x.remove(1)

 x.~.tp // Prints ~(A, D)

Reorganizes elements

Reorganizes elements according to the given permutation

  val im: Idx.Mutable[Int] = (0 <> 9).~.toBuffer

  val p = Idx.Permutation.pairs(3 -> 7, 7 -> 3, 4 -> 6, 6 -> 4)

  im.~.tp
  im.reposition(p)
  im.~.tp

  // Output
  ~(0, 1, 2, 3, 4, 5, 6, 7, 8, 9)
  ~(0, 1, 2, 7, 6, 5, 4, 3, 8, 9)

Sort elements

Sorts elements in this container

Update many at position

Replaces elements starting at given position with stream values

Update at position

Replaces element at given position with given value

  val im: Idx.Mutable[Int] = (0 <> 7).~.toBuffer

  im.updateAt(7, 777)
  im.updateAt(3, 333)

  im.~.tp // Prints ~(0, 1, 2, 333, 4, 5, 6, 777)

  // The same can be done with Scala symplified syntax

  im(7) = 777
  im(3) = 333

Returns a Stream of all elements

The element order is same as in the Idx itself

  val l: Idx[Char] = ('a' <> 'g').~.><

  l.~.tp  // Prints ~(a, b, c, d, e, f, g)

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.~.tp // ~~(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.~.tp // Prints ~(1, 2, 3, 4, 5, 6)

Alias for removeAll

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

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

Alias for remove

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

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

Optional add

Adds element if option has value, does nothing for void option

Returns element at specified position

 val idx: Idx[Char] = ('A' <> 'Z').~.><

 idx(1).tp // Prints: B

 idx(4).tp // Prints: E

Check if contains

Returns true if given element is contained by the implementing container

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

Sort by property

Sorts elements in this container based on given property map

Sort by two properties

Sorts elements in this container based on given two properties

Sort by three properties

Sorts elements in this container based on given three properties

Sort in reverse
