      • toStorageStrings

        public java.lang.String[] toStorageStrings​(java.lang.Throwable aValue)
        A Column implementation can provide its own text exchange format for the given objects. This method enables the Column to convert a value of the given type to a String array and via Column.fromStorageStrings(String[]) back to the value (bijective). This method supports data sinks (such as Amazon's SimpleDb) which provide dedicated support for multiple values in a row's entry: In case T is an array type, then the storage String representations of the elements in that array may be placed in dedicated entries of the returned String array. In case T is not an array type then the returned String array may contain just one value. In case data sinks (such as relational databases) are to be addressed which allow only a single value in a row's entry, then the method Column.toStorageString(Object) may be used instead.
        Specified by:
        toStorageStrings in interface Column<java.lang.Throwable>
        Parameters:
        aValue - the element to be converted to a String array.
        Returns:
        The String array representation of the value.

      • fromStorageStrings

        public java.lang.Throwable fromStorageStrings​(java.lang.String[] aStringValues)
                                       throws java.text.ParseException
        A Column implementation can provide its own text exchange format for the given objects. This method enables the Column to convert a String array value to a value of the given type and via Column.toStorageStrings(Object) back to the String array (bijective). This method supports data sinks (such as Amazon's SimpleDb) which provide dedicated support for multiple values in a row's entry: In case T is an array type, then the storage String representations of the elements in that array may be placed in dedicated entries of the provided String array. In case T is not an array type then the passed String array may contain just one value. In case data sinks (such as relational databases) are to be addressed which allow only a single value in a row's entry, then the method Column.fromStorageString(String) may be used instead.
        Specified by:
        fromStorageStrings in interface Column<java.lang.Throwable>
        Parameters:
        aStringValues - The value to be converted to a type instance.
        Returns:
        The type representation of the value.
        Throws:
        java.text.ParseException - in case parsing the String was not possible

      • toPrintable

        public java.lang.String toPrintable​(java.lang.Throwable aValue)
        A Column implementation can provide its own printable format of the given objects; for example a human readable text representation of the value (or in very specialized cases even enriched with ANSI escape codes). This method enables the Column to convert a value of the given type to a human readable text. The human readable text, in comparison to the method Object.toString() (or Column.toStorageString(Object)) is not intended to be converted back to the actual value (not bijective). This method may be used a Header instance's method HeaderRow.toPrintable(Record).
        Specified by:
        toPrintable in interface Column<java.lang.Throwable>
        Overrides:
        toPrintable in class AbstractColumn<java.lang.Throwable>
        Parameters:
        aValue - the element to be converted to a human readable text.
        Returns:
        The human readable representation of the value.

      • clone

        public java.lang.Object clone​()
                       throws java.lang.CloneNotSupportedException
        Overrides:
        clone in class AbstractColumn<java.lang.Throwable>
        Throws:
        java.lang.CloneNotSupportedException
