Class MBeanFeatureInfo

    • 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.
        Since:
        1.6
    • Method Detail

      • 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
      • hashCode

        public int hashCode()
        Description copied from class: Object
        Returns a hash code value for the object. This method is supported for the benefit of hash tables such as those provided by HashMap.

        The general contract of hashCode is:

        • Whenever it is invoked on the same object more than once during an execution of a Java application, the hashCode method must consistently return the same integer, provided no information used in equals comparisons on the object is modified. This integer need not remain consistent from one execution of an application to another execution of the same application.
        • If two objects are equal according to the equals(Object) method, then calling the hashCode method on each of the two objects must produce the same integer result.
        • It is not required that if two objects are unequal according to the Object.equals(java.lang.Object) method, then calling the hashCode method on each of the two objects must produce distinct integer results. However, the programmer should be aware that producing distinct integer results for unequal objects may improve the performance of hash tables.

        As much as is reasonably practical, the hashCode method defined by class Object does return distinct integers for distinct objects. (This is typically implemented by converting the internal address of the object into an integer, but this implementation technique is not required by the Java™ programming language.)

        Overrides:
        hashCode in class Object
        Returns:
        a hash code value for this object.
