      • createResultSetRowsForArrayData

        private java.util.List<java.util.List<java.lang.Object>> createResultSetRowsForArrayData​(java.lang.Iterable<java.lang.Object> elements)
        Creates the row-level view over the values that will make up an Array. The Iterator has a row per Array element, each row containing two columns. The second column is the array element and the first column is the offset into the array of that array element (one-based, not zero-based).

        The ordering of the rows is not guaranteed to be in the same order as the array elements.

        A list of elements: 

        [1, 2, 3]

        might be converted into 

        Iterator{ [1, 1], [2, 2], [3, 3] }
        Parameters:
        elements - The elements of an array.

      • createRowForArrayData

        private java.util.Iterator<java.util.List<java.lang.Object>> createRowForArrayData​(java.util.List<java.lang.Object> elements)
        Creates an row-level view over the values that will make up an Array. The Iterator has one entry which has a list that also has one entry.

        A provided list of elements 

        [1, 2, 3]

        would be converted into 

        Iterator{ [ [1,2,3] ] }
        Parameters:
        elements - The elements of an array
