Constructor Detail

ClassifierFactory

private ClassifierFactory()
                   throws java.io.IOException,
                          TrainingDataException

Creates a new instance of ClassifierFactory.

Throws:

java.io.IOException

TrainingDataException

Method Detail

resetDefaultDataProp

public static void resetDefaultDataProp()

Resets the data property file to the default data property file.

setDataProp

public static void setDataProp(java.lang.String properties,
                               boolean relative)

Sets the property file which contains the mapping of the training files. The actually training data files should be in the same directory as this property file. To override the default property location, this method must be called before the first ClassifierFactory.getFactory() call.

getFactory

public static ClassifierFactory getFactory()
                                    throws java.io.IOException,
                                           TrainingDataException

Returns a factory with the training information. This method initialize all the training information. Note: the ClassifierFactory.setDataProp() static method must be called before this method if default property file will not be used.

Throws:

java.io.IOException

TrainingDataException

getNonDefaultFactory

private static ClassifierFactory getNonDefaultFactory()
                                               throws java.io.IOException,
                                                      TrainingDataException

Returns a factory with the training information for the non-default training data files.

Throws:

java.io.IOException

TrainingDataException

convert

private static java.lang.String convert(java.lang.String key)
                                 throws java.io.IOException

Retrieves appropriate value from the property file.

Throws:

java.io.IOException
