### Abstract Value Members

1. #### abstract def +=(elem: A): Growable.this.type

   adds a single element to this growable collection.

   adds a single element to this growable collection.

   elem

     the element to add.

   returns

     the growable collection itself

2. #### abstract def clear(): Unit

   Clears the growable collection's contents.

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

   elem1

     the first element to add.

   elem2

     the second element to add.

   elems

     the remaining elements to add.

   returns

     the growable collection itself
