# RecordingMap

`class RecordingMap<K, V> : MutableMap<K, V>`

A RecordingMap wraps a regular Map<K, V> and records the sequence of gets and puts to it. This is useful in white box unit tests to ensure that code is accessing a data store as much as you expect.

Note: although this class itself thread safe, if the underlying map is not, then this class loses its thread safety.

### Types

Get | `data class Get<out K> : Record`
Put | `data class Put<out K, out V> : Record`
Record | `interface Record`

### Constructors

<init> | `RecordingMap(wrappedMap: MutableMap<K, V>, logger: <ERROR CLASS> = loggerFor<RecordingMap<K, V>>())` A RecordingMap wraps a regular Map<K, V> and records the sequence of gets and puts to it. This is useful in white box unit tests to ensure that code is accessing a data store as much as you expect.
