    • query

      protected final Query query

  • Method Details

    • getColumnNames

      public String[] getColumnNames()
      Description copied from interface: Result
      Get the list of column names.
      Specified by:
      getColumnNames in interface Result
      Returns:
      the column names

    • getColumnSelectorNames

      public String[] getColumnSelectorNames()
      Description copied from interface: Result
      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.
      Specified by:
      getColumnSelectorNames in interface Result
      Returns:
      the distinct selector names

    • getSelectorNames

      public String[] getSelectorNames()
      Description copied from interface: Result
      Get the list of selector names.
      Specified by:
      getSelectorNames in interface Result
      Returns:
      the selector names

    • getRows

      public Iterable<? extends ResultRow> getRows()
      Description copied from interface: Result
      Get the rows.
      Specified by:
      getRows in interface Result
      Returns:
      the rows

    • getSize

      public long getSize()
      Description copied from interface: Result
      Get the number of rows, if known. If the size is not known, -1 is returned.
      Specified by:
      getSize in interface Result
      Returns:
      the size or -1 if unknown

    • getSize

      public long getSize(Result.SizePrecision precision, long max)
      Description copied from interface: Result
      Get the number of rows, if known. If the size is not known, -1 is returned.
      Specified by:
      getSize in interface Result
      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.
