# enum
The enum is at its core a [string](string.md) with the length of the longest member of the enum.
It also has a default expectation of [values_to_be_in_set](../expectations/values_to_be_in_set.md).

## Input Data Format
A JSON string.

## Data Expectations
All expectations of a [string](string.md) apply.

While we don't currently enforce that input values are in the set, the expectation is that
we will start doing so soon (TM).

## Arguments
* `values` - The list of members of this enum.  Limitations of `values_to_be_in_set` apply.

## Examples
* [origin](../fields/origin.yaml)
