      • serialVersionUID

        public static final long serialVersionUID
        This fulfils the SerialVersion UID requirement for all classes that implement Java's interface java.io.Serializable. 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.

        Note that Java's java.lang.Exception and java.lang.Error classes implement the Serializable interface, and a warning-free build expects this field be defined here.

        This is a helpful message explaining how to ensure that a sub-section of a vectorized-HTML Documentation Web-Page is properly formatted according to the 'details' section of a Java-Doc page.

    • Constructor Detail

      • DetailsException

        public DetailsException()
        Constructs a DetailsException with no detail message.

      • DetailsException

        public DetailsException​(java.lang.String message)
        Constructs a DetailsException with the specified detail message.
        Parameters:
        message - the detail message.

      • DetailsException

        public DetailsException​(java.lang.String message,
                        java.lang.Throwable cause)
        Constructs a new exception with the specified detail message and cause.

        NOTE: The detail message associated with cause is not automatically incorporated in this exception's detail message.
        Parameters:
        message - The detail message (which is saved for later retrieval by the Throwable.getMessage() method).
        cause - the cause (which is saved for later retrieval by the Throwable.getCause() method). (A null value is permitted, and indicates that the cause is nonexistent or unknown.)

      • DetailsException

        public DetailsException​(java.lang.Throwable cause)
        Constructs a new exception with the specified cause and a detail message of (cause==null ? null : cause.toString()) (which typically contains the class and detail message of cause). This constructor is useful for exceptions that are little more than wrappers for other throwables.
        Parameters:
        cause - The cause (which is saved for later retrieval by the Throwable.getCause() method). (A null value is permitted, and indicates that the cause is nonexistent or unknown.)

    • Method Detail

      • check

        public static void check​(java.util.Vector<HTMLNode> details)
        This check method is used to ensure that a passed-parameter vectorized-HTML sub-page to one of the DetailsMethods, DetailsConstructors or DetailsFields is a properly formatted HTML Sub-Section. The purpose of the iterators within class Details is to retrieve the individual, detailed descriptions for the fields, methods and constructors from an HTML Page generated by the Java-Doc tool. This exception class will do some simple, basic parameter checking to ensure that the parameters passed to the extensions to class Details - which, again, are DetailsMethods, DetailsConstructors and DetailsFields. The priority is to provide more useable and meaningful error information to make it easy to alter, upgrade or modify an HTML Page generated by JavaDoc.
        Parameters:
        details - This is supposed to be the return value from a call to the HNLIInclusive iter.next() method. The iterator should be one returned from the class Details iterator' methods. If it was, then it should a guarantee that the section is properly formatted, because it would have been retrieved from a JavaDoc HTML page.
        Throws:
        DetailsException - This exception shall throw if any of the requirements of the section have not been met.
