  - ### Constructor Detail

    - #### ClosureConverter

          protected ClosureConverter​(java.lang.Class<?> type,
                                     Closure<?> closure)

  - ### Method Detail

    - #### handles

          public boolean handles​(java.lang.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 java.lang.Object convert​(java.lang.Object value,
                                          java.lang.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​(java.lang.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 `java.lang.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 `java.lang.Object`

    - #### toString

          public java.lang.String toString()

      Overrides:
        `toString` in class `java.lang.Object`
