Class HTMLNotFoundException

  • All Implemented Interfaces:
    java.io.Serializable

    public class HTMLNotFoundException
    extends java.lang.RuntimeException
    HTMLNotFoundException - Documentation.

    One of the more difficult issues that can happen when writing HTML Methods that parse and search for section and elements that are not actually present on the page or sub-page being searched. If a section of HTML does not contain an element that a programmer expects it to contain, any search method that returns a DotPair would return 'null'. Rather than allowing a method to throw an unintended NullPointerException just because the used 'Find' returned a null reference - it is better to check the result of a search, and if the section was not found to throw an HTMLNotFoundException.

      • 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.

    • Constructor Detail

      • HTMLNotFoundException

        public HTMLNotFoundException()
        Constructs an HTMLNotFoundException with no detail message.
      • HTMLNotFoundException

        public HTMLNotFoundException​(java.lang.String message)
        Constructs an HTMLNotFoundException with the specified detail message.
        Parameters:
        message - the detail message.
      • HTMLNotFoundException

        public HTMLNotFoundException​(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.)
      • HTMLNotFoundException

        public HTMLNotFoundException​(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.)
