- org.apache.druid.query.groupby.ResultRow

```
public final class ResultRow
extends Object
```
Used by GroupByQuery for results. Each row is positional, and has the following fields, in order: - Timestamp (optional; only if granularity != ALL) - Dimensions (in order) - Aggregators (in order) - Post-aggregators (optional; in order, if present) ResultRows may sometimes be created without space reserved for post-aggregators, in contexts where it is known that post-aggregators will not be computed.

```
public static ResultRow of(Object... row)
```
    Create a row from an array of objects.
  - create
```
public static ResultRow create(int size)
```
    Create a row of a certain size, initialized to all nulls.
  - fromLegacyRow
```
public static ResultRow fromLegacyRow(Row row,
                                      GroupByQuery query)
```
    Create a row based on a legacy Row that was generated by a given GroupByQuery. This is useful for deserializing rows that have come off the wire in the older format. (In the past, GroupBy query results were sequences of Row, not ResultRow.)
    
    Parameters:
    
    row - legacy row
    
    query - query corresponding to the output ResultRow
  - getArray
```
public Object[] getArray()
```
    Get the backing array for this row (not a copy).
  - set
```
public void set(int i,
                @Nullable
                Object o)
```
  - get
```
@Nullable
public Object get(int i)
```
  - getLong
```
public long getLong(int i)
```
  - length
```
public int length()
```
  - copy
```
public ResultRow copy()
```
    Returns a copy of this row. The backing array will be copied as well.
  - toMap
```
public Map<String,Object> toMap(GroupByQuery query)
```
    Returns a Map representation of the data in this row. Does not include the timestamp.
  - toMapBasedRow
```
public MapBasedRow toMapBasedRow(GroupByQuery query)
```
    Returns a Row representation of the data in this row.
  - equals
```
public boolean equals(Object o)
```
    Overrides:
    
    equals in class Object
  - hashCode
```
public int hashCode()
```
    Overrides:
    
    hashCode in class Object
  - toString
```
public String toString()
```
    Overrides:
    
    toString in class Object
