 In this example, 3 methods are public endpoints. They are named `example`, `camelCaseEndpointName` and `getData`. All other names are internal and do not show up in the resulting contract.

 First off, please note that a storage method can also be annotated with `#[view]` or `#[endpoint]`. The endpoint annotations refer to the role of the method in the contract, while the storage annotation refers to its implementation, so there is no overlap.

 It works very similarly to `storage_get`, with the notable difference that instead of returning a value, the value must be provided as an argument. The value to store is always the last argument.

 There is no mechanism in place to ensure that there is no overlap between storage keys. Nothing prevents a developer from writing:

 The `SingleValueMapper` is the simplest of them all, since it only manages one storage key. Even though it only works with one storage entry, its syntax is more compact than `storage_get`/`storage_set` so it is used quite a lot.
