HNil

The type of the first element

The type of this HList object

The type of the tail of this HList

The type of prepending an element of type E to this HList

Get the first element, or throw a NoSuchElementException if this HList is empty.

Check if this HList is non-empty.

Return this HList typed as Self/

Get the tail of the list, or throw a NoSuchElementException if this HList is empty.

Convert this HList to a List[Any].

Prepend an element to this HList, returning a new HList.

Drop the first n elements from this HList.

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)).

Evaluate a function for each element of this HList.

Check if this list is empty.

Get the length of this list.

Get the length of this list as an Int.

Returns a string representation of the object.

The default representation is platform dependent.

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.
