Concrete methods

def apply[K, V](firstElement: (K, V), otherElements: (K, V)*): NonEmptyMap[K, V]

Constructs a new NonEmptyMap given at least one element.

Attributes

K

the type of the key contained in the new NonEmptyMap

V

the type of the value contained in the new NonEmptyMap

firstElement

the first element (with index 0) contained in this NonEmptyMap

otherElements

a varargs of zero or more other elements (with index 1, 2, 3, ...) contained in this NonEmptyMap

def from[K, V](seq: Seq[(K, V)]): Option[NonEmptyMap[K, V]]

Optionally construct a NonEmptyMap containing the elements, if any, of a given Seq.
