Interface Result

public interface Result
A result from executing a query.

  • Method Details

    • 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

    • getRows

      Iterable<? extends ResultRow> getRows()
      Get the rows.
      Returns:
      the rows

    • 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.
