Type Parameters:

X - The type of the feature description of a single instance.

All Superinterfaces:

IInstanceSchemaHandler

All Known Subinterfaces:

IDyadRankingInstance, ILabeledInstance, ILabelRankingInstance, IMultiLabelClassificationInstance, IRankingInstance<O>, IRegressionInstance, ISingleLabelClassificationInstance
```
public interface IInstance
extends IInstanceSchemaHandler
```
Instances implementing this interface have a feature description of the type X. Usually, feature descriptions are realized via double arrays. However, here it is also allowed to specify feature descriptions which are heteregoneous (e.g., a time series with single values) and may consist of complex objects (e.g., lists, arrays, graphs).
