```
public interface AdaptiveFeatureGenerator
```
An interface for generating features for name entity identification and for updating document level contexts.
Note:
Feature generation is not thread safe and a instance of a feature generator must only be called from one thread. The resources used by a feature generator are typically shared between man instances of features generators which are called from many threads and have to be thread safe.

Method Summary

All Methods Instance Methods Abstract Methods Default Methods
Modifier and Type	Method	Description
`default void`	`clearAdaptiveData()`	Informs the feature generator that the context of the adaptive data (typically a document) is no longer valid.
`void`	`createFeatures(java.util.List<java.lang.String> features, java.lang.String[] tokens, int index, java.lang.String[] previousOutcomes)`	Adds the appropriate features for the token at the specified index with the specified array of previous outcomes to the specified list of features.
`default void`	`updateAdaptiveData(java.lang.String[] tokens, java.lang.String[] outcomes)`	Informs the feature generator that the specified tokens have been classified with the corresponding set of specified outcomes.

  - createFeatures
```
void createFeatures(java.util.List<java.lang.String> features,
                    java.lang.String[] tokens,
                    int index,
                    java.lang.String[] previousOutcomes)
```
    Adds the appropriate features for the token at the specified index with the specified array of previous outcomes to the specified list of features.
    
    Parameters:
    
    features - The list of features to be added to.
    
    tokens - The tokens of the sentence or other text unit being processed.
    
    index - The index of the token which is currently being processed.
    
    previousOutcomes - The outcomes for the tokens prior to the specified index.
  - updateAdaptiveData
```
default void updateAdaptiveData(java.lang.String[] tokens,
                                java.lang.String[] outcomes)
```
    Informs the feature generator that the specified tokens have been classified with the corresponding set of specified outcomes.
    
    Parameters:
    
    tokens - The tokens of the sentence or other text unit which has been processed.
    
    outcomes - The outcomes associated with the specified tokens.
  - clearAdaptiveData
```
default void clearAdaptiveData()
```
    Informs the feature generator that the context of the adaptive data (typically a document) is no longer valid.
