Class JsonBindingArrException



    • Field Detail

      • 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.

        public final int index
        This field is provided to the user as a matter of convenience. All instantiations of this Exception are guaranteed to enforce and ensure that when an instance of this exception is thrown, the convenience field will not be null. If this package is extended, it is up to the programmer/user to make sure not to leave this field null when using one of these constructors. This constructor will not check whether a convenience field is null or not, when constructing the exception.

        IMPORTANT: All this is really trying to explain is that, when debugging your code, if in the analysis of a particular Exception, that analysis causes another exception throw (like NullPointerException) - BECAUSE THIS CONVENIENCE FIELD WAS LEFT NULL - would be an unnecessary source of headache.

        This is the array index into the source JsonArray which contained the element (or lack-there-of) that has caused this exception.

                                       java.lang.String endingNote)
        Constructs a JsonBindingArrException with no specified detail messsage, and the user-provided convenience-field values.
        Parameters:
        errorSourceJsonArray - The JsonArray from which the element is being retrieved / extracted.
        index - This is the JsonArray index from which the element is being retrieved / extracted.
        expectedJsonType - This is the Json-Type that was expected to be retrieved from JsonArray.
        valueRetrieved - This is the JsonValue that was extracted from the JsonArray which caused an exception. Note that if the entity did not exist, then this parameter will be Java-Null. If Json-Null was found, then this parameter should be JsonValue.NULL
        methodReturnJavaType - Class ReadJSON will always provide the ultimate Java-Type that is to be returned by the method where this exception is being thrown.
        endingNote - The distinct message for the exception sub-class.

        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.)
        errorSourceJsonArray - The JsonArray from which the element is being retrieved / extracted.
        index - This is the JsonArray index from which the element is being retrieved / extracted.
        expectedJsonType - This is the Json-Type that was expected to be retrieved from JsonArray.
