      • setAttribute

        void setAttribute​(String name,
                  Object value)
        Adds a new query attribute to the list of query attributes. Implementations must validate the type of the given the object and reject it or replace it by another representation if not supported, by its String version, for example. Query attribute names are not checked for duplication.
        参数:
        name - the query attribute name.
        value - the query attribute value.

      • getCount

        int getCount()
        Get the count of query attributes in the list.
        返回:
        the number of query attributes existing in the list.

      • getAttributeValue

        BindValue getAttributeValue​(int index)
        Returns an internal representation of the query attribute in the given position of the query attributes list. It's implementation dependent what to do when the index value is invalid.
        参数:
        index - the position of the query attribute value to return.
        返回:
        the BindValue in the given position of the query attributes list.
