- ## Method Details

  - ### readableMap

    public static <K, V> IterableMap<K,V> readableMap(Get<K,V> get)
    Gets the specified `Get` as an instance of `IterableMap`. If `get` implements `IterableMap` directly, no conversion will take place. If `get` implements `Map` but not `IterableMap` it will be decorated. Otherwise, an `Unmodifiable` `IterableMap` will be returned.
    Type Parameters:
      `K` - the key type
      `V` - the value type
    Parameters:
      `get` - to wrap, must not be null
    Returns:
      `IterableMap`
    Throws:
      `NullPointerException` - if the argument is null

  - ### writableMap

    public static <K, V> Map<K,V> writableMap(Put<K,V> put)
    Gets the specified `Put` as an instanceof `Map`. If `put` implements `Map` directly, no conversion will take place. Otherwise, a write-only `Map` will be returned. On such a `Map` it is recommended that the result of #put(K, V) be discarded as it likely will not match `V` at runtime.
    Type Parameters:
      `K` - the key type
      `V` - the element type
    Parameters:
      `put` - to wrap, must not be null
    Returns:
      `Map`
    Throws:
      `NullPointerException` - if the argument is null
