```

Reverse the order of the elements in the given GroupedScalar\<any, any>

#### Parameters

<table><thead><tr><th width="172">Parameter</th><th>Description</th></tr></thead><tbody><tr><td>group</td><td>A GroupedScalar of type &#x3C;any, any></td></tr></tbody></table>

#### Returns

Returns the given group in reversed order with type GroupedScalar\<any, any>.

### REVERSE(GroupedVector\<any, any>)

```java
REVERSE(group: GroupedVector<any,any>): GroupedVector<any,any>
```

Reverse the order of the elements in the given GroupedVector\<any, any>

#### Parameters

<table><thead><tr><th width="172">Parameter</th><th>Description</th></tr></thead><tbody><tr><td>group</td><td>A GroupedVector of type &#x3C;any, any></td></tr></tbody></table>
