Returns a BAggregateArea that contains only primitive geometries. Any aggregates (e.g. BAggregateArea or BDonut) will be flattened, and their geometries added to this collection.

Initializes an instance of this object from a BByteArray.
| bytes | The BByteArray containing the byte representation for this object. | |
