- ## Field Details

  - ### 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 Details

  - ### 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.
    Since:
      1.6

- ## Method Details

  - ### getName

    public String getName()
    Returns the name of the feature.
    Returns:
      the name of the feature.

  - ### 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.
    Since:
      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.
