# `GSShapeGroup containsShape:`

*Instance Method*

Returns whether the given shape is a member of the group.

## Declaration

```swift
func containsShape(_ shape: GSShape) -> Bool
```

```objc
- (BOOL) containsShape:(GSShape *) shape;
```

```python
containsShape_(shape: GSShape) -> bool
```

## Discussion

> **Complexity**
> O(log(*n*)) where *n* is the number of members of the group. O(*n*) when the group or shape has a layer of `nil`.
