Class AnnotationElem

  • All Implemented Interfaces:, java.lang.Cloneable, java.lang.Comparable<AnnotationElem>

    public class AnnotationElem
    extends Declaration
    implements, java.lang.Comparable<AnnotationElem>, java.lang.Cloneable
    Java Parser Bridge: Holds all information extracted from '.java' Annotation (@interface) Source Files about all Elements identified in that file.

    Instances of this Class are Obtained From: ReflHTML & SummaryTableHTML

    Use of the Reflection-HTML API is *NOT REQUIRED* to perform a standard Java Doc HTML File Upgrade. This "extra API" allows for programmatic modification of Java Doc HTML. This class contains quite a bit of reflected information, and furthermore, here there is a hook to the Native Java Parser Reflection Class.
    The purpose of this bridge is provide a pared down, easier-to-use (but-with less-features) version of the publicly available "JavaParser" package. This class AnnotationElem allows for storing the name, definition, default-value, etc... of an Annotation Element. Note that an 'Annotation Element' is not the same as a Java 'Annotation' (@interface). An 'Annotation Element' is merely the (optional) element / parameter which may (if used) help specify the contents of a Java Annotation.

    For Instance: With the commonly-used annotation named @SuppressWarnings(...), the value-parameters that are passed inside the parenthesis are the 'value' Annotation-Element. This 'value' may be assigned several Java String's such as: 'rawtypes', 'unchecked', etc...

    There is a Java-Parser Library that is required to use this Package. The Java Doc Upgrader Package / Tool will not work without this '.jar'file being placed in your CLASSPATH environment-variable. That '.jar'is available here:

    There is a book available and an internet "Gitter" support web-site chat-room with some of the people involved in writing this library. There are quite a number of available jars in the "Master Jar Distribution" - but the core library jar is fully sufficient for running the tasks needed by this Java-Doc Upgrade Tool's logic.

    All reflection classes above, also contain an additional (transient, non-Serializable) field that hooks into the native Java-Parser Library classes, providing an option for a more in-depth or complete analysis using that Library's features & extensive utilities.

      • serialVersionUID

        public static final long serialVersionUID
        This fulfils the SerialVersion UID requirement for all classes that implement Java's interface Using the Serializable Implementation offered by java is very easy, and can make saving program state when debugging a lot easier. It can also be used in place of more complicated systems like "hibernate" to store data as well.

        public final java.lang.String type
        An Annotation-Element may only assume one of several types, as per the Java Sun / Oracle Documentation. The type must be one of the following, or a compile-time error occurs:

        • a primitive type
        • String
        • Class or an invocation of Class
        • An enum type
        • An annotation type
        • An (1 dimensional) array type whose component type is one of the preceding types
        Exact Field Declaration Expression:
        public final String type;

      • defaultValue

        🡅  🡇

        Hook Reference to Java-Parser Refletion Class

        Though this class offers a streamlined set of reflection features, the Native Java-Parser Library Reflection-Classes offer a near-complete set of analysis tools for just about any kind of code-analysis neccessary. If you would like your Java Doc Pages to include more analytical-information, this field is provided as a convenience for such purposes.
        If a user decides to make use of the Java-Parser AnnotationMemberDeclaration instance that was used to build this AnnotationEleme, it may be retrieved from this transient field.
        Exact Field Declaration Expression:
        public final transient AnnotationMemberDeclaration annotationMemberDeclaration;

        public AnnotationElem​
                    (com.github.javaparser.ast.body.AnnotationMemberDeclaration amd)
        Instantiates a AnnotationElem, and peels out the String's from a JavaParser AnnotationMemberDeclaration

        EXCEPTIONS NOTE: The underlying parser code can throw exceptions, and the exception chain, and exception tree in the package is quite dense. Suffice it to say, they are all unchecked exceptions.
        amd - This can be retrieved in any number of ways from the JavaParser package. The instantiation process will convert a Java-Parser from of an AnnotationMemberDeclaration, into this Bridge form class AnnotationElem.

        Yes, this is redundant, but that's what a bridge is - a wrapper class to make the programmer's life easier. All the salient information a programmer would need when improving JavaDoc Documentation HTML Files is easily and simply encapsulated as lists of String's in the class AnnotationElem.

      • clone

        🡅  🡇    
        public AnnotationElem clone()
        Java's interface Cloneable requirements. This instantiates a new AnnotationElem with identical fields.
        clone in class java.lang.Object
        A new AnnotationElem whose internal fields are identical to this one. A deep copy on all internal arrays is performed. New arrays are instantiated.

      • compareTo

        🡅  🡇    
        public int compareTo​(AnnotationElem ae)
        Java's interface Comparable<T> requirements. This does a very simple comparison using the two elements' 'name' field.
        Specified by:
        compareTo in interface java.lang.Comparable<AnnotationElem>
        ae - Any other AnnotationElem to be compared to 'this' AnnotationElem
        An integer that fulfills Java's interface Comparable<AnnotationElem> public boolean compareTo(AnnotationElem ae) method requirements.
        Exact Method Body:
         return (this == ae) ? 0 :;
      • equals

        public boolean equals​(AnnotationElem other)
        This should be called an "atypical version" of the usual equals(Object other) method. This version of equals merely compares the name of the element defined. The presumption here is that the definition of an 'element' only has meaning - at all - inside the context of an Annotation where that element has been defined. Since inside any '.java' Annotation, there may only be one element with a given name, this method shall return TRUE whenever the element being compared also has the same name.
        other - This may be any other Annotation-Element. It is strongly suggested that 'other' be an element defined in the same '.java' source-code file as 'this' element.
        This method returns TRUE when 'this' instance of AnnotationElem has the same 'name' as the name of input-parameter 'other'
