Interface Result

  • public interface Result
    A result from executing a query.

    • Method Detail

      • getColumnNames

        String[] getColumnNames()
        Get the list of column names.
        Returns:
        the column names

      • getColumnSelectorNames

        String[] getColumnSelectorNames()
        Get the distinct selector names of all columns. The list is ordered as selectors appear in the result. For columns without selector, an empty entry (null) is used.
        Returns:
        the distinct selector names

      • getSelectorNames

        String[] getSelectorNames()
        Get the list of selector names.
        Returns:
        the selector names

      • getSize

        long getSize()
        Get the number of rows, if known. If the size is not known, -1 is returned.
        Returns:
        the size or -1 if unknown

      • getSize

        long getSize​(Result.SizePrecision precision,
             long max)
        Get the number of rows, if known. If the size is not known, -1 is returned.
        Parameters:
        precision - the required precision
        max - the maximum number that should be returned (Long.MAX_VALUE for unlimited). For EXACT, the cost of the operation is at most O(max). For approximations, the cost of the operation should be at most O(log max).
        Returns:
        the (approximate) size. If an implementation does know the exact value, it returns it (even if the value is higher than max). If the implementation does not know the value, and the child node count is higher than max, it returns Long.MAX_VALUE.
