Constructor Detail

POSTaggerFactory

public POSTaggerFactory()

Creates a POSTaggerFactory that provides the default implementation of the resources.

POSTaggerFactory

public POSTaggerFactory(Dictionary ngramDictionary,
                        TagDictionary posDictionary)

Parameters:

ngramDictionary -

posDictionary -

Method Detail

init

protected void init(Dictionary ngramDictionary,
                    TagDictionary posDictionary)

createArtifactSerializersMap

public Map<String,ArtifactSerializer> createArtifactSerializersMap()

Description copied from class: BaseToolFactory

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.

Overrides:

createArtifactSerializersMap in class BaseToolFactory

createArtifactMap

public Map<String,Object> createArtifactMap()

Description copied from class: BaseToolFactory

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.

Overrides:

createArtifactMap in class BaseToolFactory

Throws:

InvalidFormatException

validateArtifactMap

public void validateArtifactMap()
                         throws InvalidFormatException

Description copied from class: BaseToolFactory

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.

Specified by:

validateArtifactMap in class BaseToolFactory

Throws:

InvalidFormatException
