toString

open override fun toString(): String

Returns the string representation of this collection.

Implementations of this function should behave like calling the Iterable.toString function.

Calling from Kotlin

Here's an example of calling this function from Kotlin code:

val collection: NotEmptyCollection<Int> = notEmptyListOf(1, 2, 3)
val actual = "$collection"
val expected = "${listOf(1, 2, 3)}"
assertEquals(expected, actual)
