Value members

Abstract methods

Adds a single element to this growable collection.

Adds a single element to this growable collection.

Value Params

elem: the element to add.

Returns

the growable collection itself

Concrete methods

Alias for addAll

Alias for addAll

Alias for addOne

Alias for addOne

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

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

Value Params

xs: the IterableOnce producing the elements to add.

Returns

the growable collection itself.

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

Deprecated methods

@deprecated("Use `++=` aka `addAll` instead of varargs `+=`; infix operations with an operand of multiple args will be deprecated", "2.13.0") @inline

Adds two or more elements to this growable collection.

Adds two or more elements to this growable collection.

Value Params

elem1: the first element to add.
elem2: the second element to add.
elems: the remaining elements to add.

Returns

the growable collection itself

Deprecated

Inherited methods
