Class BaseToolFactory

java.lang.Object

opennlp.tools.util.BaseToolFactory

Direct Known Subclasses:

ChunkerFactory, POSTaggerFactory, TokenizerFactory, TokenNameFinderFactory

public abstract class BaseToolFactory
extends Object

Base class for all tool factories. Extensions of this class should:

• implement an empty constructor (TODO is it necessary?)
• implement a constructor that takes the ArtifactProvider and calls BaseToolFactory(Map)
• override createArtifactMap() and createArtifactSerializersMap() methods if necessary.

Constructor Details

BaseToolFactory

public BaseToolFactory()

All sub-classes should have an empty constructor

Method Details

createArtifactSerializersMap

public Map<String,ArtifactSerializer> createArtifactSerializersMap()

Creates a Map with pairs of keys and ArtifactSerializer. The models implementation should call this method from BaseModel#createArtifactSerializersMap

The base implementation will return a HashMap that should be populated by sub-classes.

createArtifactMap

public Map<String,Object> createArtifactMap()

Creates a Map with pairs of keys and objects. The models implementation should call this constructor that creates a model programmatically.

The base implementation will return a HashMap that should be populated by sub-classes.

createManifestEntries

public Map<String,String> createManifestEntries()

Creates the manifest entries that will be added to the model manifest

Returns:

the manifest entries to added to the model manifest

validateArtifactMap

public abstract void validateArtifactMap()
                                  throws InvalidFormatException

Validates the parsed artifacts. If something is not valid subclasses should throw an InvalidFormatException. Note: Subclasses should generally invoke super.validateArtifactMap at the beginning of this method.

Throws:

InvalidFormatException

create

public static BaseToolFactory create(String subclassName,
 ArtifactProvider artifactProvider)
                              throws InvalidFormatException

Throws:

InvalidFormatException

create

public static BaseToolFactory create(Class<? extends BaseToolFactory> factoryClass,
 ArtifactProvider artifactProvider)
                              throws InvalidFormatException

Throws:

InvalidFormatException
