  - ### ConfigurationMap

    public ConfigurationMap(Configuration configuration)
    Creates a new instance of a `ConfigurationMap` that wraps the specified `Configuration` instance.
    Parameters:
      `configuration` - `Configuration` instance.

- ## Method Details

  - ### entrySet

    public Set<Map.Entry<Object,Object>> entrySet()
    Returns a set with the entries contained in this configuration-based map.
    Specified by:
      `entrySet` in interface `Map<Object,Object>`
    Specified by:
      `entrySet` in class `AbstractMap<Object,Object>`
    Returns:
      a set with the contained entries
    See Also:
      - `Map.entrySet()`

  - ### get

    public Object get(Object key)
    Gets the value of the specified key. The key is converted to a string and then passed to the underlying configuration.
    Specified by:
      `get` in interface `Map<Object,Object>`
    Overrides:
      `get` in class `AbstractMap<Object,Object>`
    Parameters:
      `key` - the key
    Returns:
      the value of this key
    See Also:
      - `Map.get(Object)`

  - ### getConfiguration

    public Configuration getConfiguration()
    Gets the wrapped `Configuration` object.
    Returns:
      the wrapped configuration
    Since:
      1.2

  - ### put

    public Object put(Object key, Object value)
    Stores the value for the specified key. The value is stored in the underlying configuration.
    Specified by:
      `put` in interface `Map<Object,Object>`
    Overrides:
      `put` in class `AbstractMap<Object,Object>`
    Parameters:
      `key` - the key (will be converted to a string)
      `value` - the value
    Returns:
      the old value of this key or null if it is new
