# append(referenceOf:optimizeDepth:)

Append a reference to a range of another block buffer.

```
mutating func append(referenceOf other: consuming CMMutableDataBlockBuffer, optimizeDepth: Bool = true)
```

## Parameters

`optimizeDepth`

Keep the depth of buffer reference graph to a minimum.

## Discussion

The range within the block buffer is not required to be contiguous. Providing out of bounds range will result in
a precondition failure.
