MongoCollection (The Adobe AEM Quickstart and Web Application.)

Type Parameters:

TDocument - The type that this collection will encode documents from and decode documents to.
```
@ThreadSafe
public interface MongoCollection<TDocument>

The MongoCollection interface.
Note: Additions to this interface will not be considered to break binary compatibility.

MongoCollection is generic allowing for different types to represent documents. Any custom classes must have a Codec registered in the CodecRegistry.
