Document (aika 0.19 API)

java.lang.Object
- network.aika.Document

All Implemented Interfaces:

Comparable<Document>
```
public class Document
extends Object
implements Comparable<Document>
```
The Document class represents a single document which may be either used for processing a text or as training input. A document consists of the raw text, the interpretations and the activations.
When the document is not needed any more, the method clearActivations must be called, since Aika only supports a single document per thread and model.

```
Removes the activations of this document from the model again.
