    - #### MBeanConstructorInfo

          public MBeanConstructorInfo​(String description,
                                      Constructor<?> constructor)

      Constructs an `MBeanConstructorInfo` object. The `Descriptor` of the constructed object will include fields contributed by any annotations on the `Constructor` object that contain the `DescriptorKey` meta-annotation.
      Parameters:
        `description` - A human readable description of the operation.
        `constructor` - The `java.lang.reflect.Constructor` object describing the MBean constructor.

    - #### MBeanConstructorInfo

          public MBeanConstructorInfo​(String name,
                                      String description,
                                      MBeanParameterInfo[] signature)

      Constructs an `MBeanConstructorInfo` object.
      Parameters:
        `name` - The name of the constructor.
        `signature` - `MBeanParameterInfo` objects describing the parameters(arguments) of the constructor. This may be null with the same effect as a zero-length array.
        `description` - A human readable description of the constructor.

    - #### MBeanConstructorInfo

          public MBeanConstructorInfo​(String name,
                                      String description,
                                      MBeanParameterInfo[] signature,
                                      Descriptor descriptor)

      Constructs an `MBeanConstructorInfo` object.
      Parameters:
        `name` - The name of the constructor.
        `signature` - `MBeanParameterInfo` objects describing the parameters(arguments) of the constructor. This may be null with the same effect as a zero-length array.
        `description` - A human readable description of the constructor.
        `descriptor` - The descriptor for the constructor. This may be null which is equivalent to an empty descriptor.

  - ### Method Detail

    - #### clone

          public Object clone()

      Returns a shallow clone of this instance. The clone is obtained by simply calling `super.clone()`, thus calling the default native shallow cloning mechanism implemented by `Object.clone()`. No deeper cloning of any internal field is made.

      Since this class is immutable, cloning is chiefly of interest to subclasses.

      Overrides:
        `clone` in class `Object`
      Returns:
        a clone of this instance.
      See Also:
        `Cloneable`

    - #### getSignature

          public MBeanParameterInfo[] getSignature()

      Returns the list of parameters for this constructor. Each parameter is described by an `MBeanParameterInfo` object.

      The returned array is a shallow copy of the internal array, which means that it is a copy of the internal array of references to the `MBeanParameterInfo` objects but that each referenced `MBeanParameterInfo` object is not copied.

      Returns:
        An array of `MBeanParameterInfo` objects.

    - #### equals

          public boolean equals​(Object o)

      Compare this MBeanConstructorInfo to another.
      Overrides:
        `equals` in class `MBeanFeatureInfo`
      Parameters:
        `o` - the object to compare to.
      Returns:
        true if and only if `o` is an MBeanConstructorInfo such that its `MBeanFeatureInfo.getName()`, `MBeanFeatureInfo.getDescription()`, `getSignature()`, and `MBeanFeatureInfo.getDescriptor()` values are equal (not necessarily identical) to those of this MBeanConstructorInfo. Two signature arrays are equal if their elements are pairwise equal.
