- - ### Field Detail

    - #### name

          protected String name

      The name of the feature. It is recommended that subclasses call `getName()` rather than reading this field, and that they not change it.

    - #### description

          protected String description

      The human-readable description of the feature. It is recommended that subclasses call `getDescription()` rather than reading this field, and that they not change it.

  - ### Constructor Detail

    - #### MBeanFeatureInfo

          public MBeanFeatureInfo​(String name,
                                  String description)

      Constructs an `MBeanFeatureInfo` object. This constructor is equivalent to `MBeanFeatureInfo(name, description, (Descriptor) null`.
      Parameters:
        `name` - The name of the feature.
        `description` - A human readable description of the feature.

    - #### MBeanFeatureInfo

          public MBeanFeatureInfo​(String name,
                                  String description,
                                  Descriptor descriptor)

      Constructs an `MBeanFeatureInfo` object.
      Parameters:
        `name` - The name of the feature.
        `description` - A human readable description of the feature.
        `descriptor` - The descriptor for the feature. This may be null which is equivalent to an empty descriptor.

  - ### Method Detail

    - #### getName

          public String getName()

      Returns the name of the feature.
      Returns:

    - #### getDescription

          public String getDescription()

      Returns the human-readable description of the feature.
      Returns:
        the human-readable description of the feature.

    - #### getDescriptor

          public Descriptor getDescriptor()

      Returns the descriptor for the feature. Changing the returned value will have no affect on the original descriptor.
      Specified by:
        `getDescriptor` in interface `DescriptorRead`
      Returns:
        a descriptor that is either immutable or a copy of the original.

        1.6

    - #### equals

          public boolean equals​(Object o)

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