NonEmptyMap

Creates a new NonEmptyMap with an additional element, unless the element is already present.

Creates a new NonEmptyMap by adding all elements contained in another collection to this NonEmptyMap, omitting duplicates.

This method takes a collection of elements and adds all elements, omitting duplicates, into NonEmptyMap.

Example:

  scala> val a = NonEmptyMap(1, 2) ++ NonEmptyMap(2, "a")
  a: zio.prelude.NonEmptyMap[Any] = NonEmptyMap(1, 2, a)

Adds the elem to this NonEmptyMap. Alias for +.

Compares the receiver object (this) with the argument object (that) for equivalence.

Any implementation of this method should be an equivalence relation:

• It is reflexive: for any instance x of type Any, x.equals(x) should return true.
• It is symmetric: for any instances x and y of type Any, x.equals(y) should return true if and only if y.equals(x) returns true.
• It is transitive: for any instances x, y, and z of type Any if x.equals(y) returns true and y.equals(z) returns true, then x.equals(z) should return true.

If you override this method, you should verify that your implementation remains an equivalence relation. Additionally, when overriding this method it is usually necessary to override hashCode to ensure that objects which are "equal" (o1.equals(o2) returns true) hash to the same scala.Int. (o1.hashCode.equals(o2.hashCode)).

Calculate a hash code value for the object.

The default hashing algorithm is platform dependent.

Note that it is allowed for two objects to have identical hash codes (o1.hashCode.equals(o2.hashCode)) yet not be equal (o1.equals(o2) returns false). A degenerate implementation could always return 0. However, it is required that if two objects are equal (o1.equals(o2) returns true) that they have identical hash codes (o1.hashCode.equals(o2.hashCode)). Therefore, when overriding this method, be sure to verify that the behavior is consistent with the equals method.

Produces a new non empty map where values mapped according to function f. For compatibility does not use map.iew

Returns an element of this NonEmptyMap and the remainder, which is a (possibly empty) Map.

Returns an element of this NonEmptyMap and the remainder or None, if the remainder is empty.

Removes the elem from this NonEmptyMap. Alias for -.

Returns the tail of this NonEmptyMap if it exists or None otherwise.

Converts this NonEmptyMap to a Map.

Returns a string representation of the object.

The default representation is platform dependent.
