  - ### handles

    public boolean handles(Class<?> type)
    Returns `true` if this converter can handle conversions of the given type.
    Specified by:
      `handles` in interface `JsonGenerator.Converter`
    Parameters:
      `type` - the type of the object to convert
    Returns:
      true if this converter can successfully convert values of the given type

  - ### convert

    public Object convert(Object value, String key)
    Converts a given value.
    Specified by:
      `convert` in interface `JsonGenerator.Converter`
    Parameters:
      `value` - the object to convert
      `key` - the key name for the value, may be `null`
    Returns:
      the converted object

  - ### equals

    public boolean equals(Object o)
    Any two Converter instances registered for the same type are considered to be equal. This comparison makes managing instances in a Set easier; since there is no chaining of Converters it makes sense to only allow one per type.
    Overrides:
      `equals` in class `Object`
    Parameters:
      `o` - the object with which to compare.
    Returns:
      `true` if this object contains the same class; `false` otherwise.

  - ### hashCode

    public int hashCode()
    Overrides:
      `hashCode` in class `Object`

  - ### toString

    public String toString()
    Overrides:
      `toString` in class `Object`
