# Spec SimpleShape
A variable length ungapped shape (also called q-gram or k-mer).

Extends | Shape
All Extended | Shape
Defined in | <seqan/index.h>
Signature | `template <typename TValue> class Shape<TValue, SimpleShape>;`

## Template Parameters

`TValue` | The Value type of the string the shape is applied to (e.g. `Dna`).

## Member Function Overview

- `Shape::Shape();, Shape::Shape(shape);, Shape::Shape(q);`
  Constructor.
