Abstract methods

Source

def addOne(elem: A): Growable.this.type

Adds a single element to this growable collection.

Value parameters	elem the element to add.
Returns	the growable collection itself

Concrete methods

Source

final def ++=(xs: IterableOnce[A]): Growable.this.type

Alias for addAll

Source

final def +=(elem: A): Growable.this.type

Alias for addOne

Source

def addAll(xs: IterableOnce[A]): Growable.this.type

Adds all elements produced by an IterableOnce to this growable collection.

Value parameters	xs the IterableOnce producing the elements to add.
Returns	the growable collection itself.

Source

def knownSize: Int

Returns	The number of elements in the collection under construction, if it can be cheaply computed, -1 otherwise. The default implementation always returns -1.

Inherited methods

def clear(): Unit

Clears the collection's contents. After this operation, the collection is empty.
