Class EnsembleLibrary

    java.lang.Object
      weka.classifiers.EnsembleLibrary

All Implemented Interfaces:
  java.io.Serializable, RevisionHandler

Direct Known Subclasses:
  EnsembleSelectionLibrary

    public class EnsembleLibrary

extends java.lang.Object
implements java.io.Serializable, RevisionHandler

This class represents a library of classifiers. This class follows the factory design pattern of creating LibraryModels when asked. It also has the methods necessary for saving and loading models from lists.

### createModel

    public EnsembleLibraryModel createModel(Classifier classifier)

  creates a LibraryModel from a string representing the command line invocation

  Parameters:
    `classifier` - the classifier to create a model from
  Returns:
    the generated model

### createModel

    public EnsembleLibraryModel createModel(java.lang.String modelString)

  This method takes a String argument defining a classifier and uses it to create a base Classifier.

  Parameters:
    `modelString` - the classifier string
  Returns:
    the generated model

### getModels

    public java.util.TreeSet getModels()

  getter for the set of models in this library

  Returns:
    the current models

### setModels

    public void setModels(java.util.TreeSet models)

  setter for the set of models in this library

  Parameters:

### clearModels

    public void clearModels()

  removes all models from the current library

### loadLibrary

    public static void loadLibrary(java.io.File selectedFile,
                                   javax.swing.JComponent dialogParent,
                                   EnsembleLibrary library)

  Loads and returns a library from the specified file

  Parameters:
    `selectedFile` - the file to load from
    `dialogParent` - the parent component
    `library` - will contain the data after loading

### loadLibrary

    public static void loadLibrary(java.io.File selectedFile,
                                   EnsembleLibrary library)
                            throws java.lang.Exception

  This method takes a model list file and a library object as arguments and Instantiates all of the models in the library list file. It is assumed that the passed library was an associated working directory and can take care of creating the model objects itself.

  Parameters:
    `selectedFile` - the file to load
    `library` - the library
  Throws:
    `java.lang.Exception` - if something goes wrong

### loadLibrary

                            throws java.lang.Exception

  This method takes an XML input stream and a library object as arguments and Instantiates all of the models in the stream. It is assumed that the passed library was an associated working directory and can take care of creating the model objects itself.

  Parameters:
    `stream` - the XML stream to load
    `library` - the library
  Throws:
    `java.lang.Exception` - if something goes wrong

### saveLibrary

    public static void saveLibrary(java.io.File selectedFile,
                                   EnsembleLibrary library,
                                   javax.swing.JComponent dialogParent)

  Saves the given library in the specified file. This saves only the specification of the models as a model list.

  Parameters:
    `selectedFile` - the file to save to
    `library` - the library to save
    `dialogParent` - the component parent

### addPropertyChangeListener

    public void addPropertyChangeListener(java.beans.PropertyChangeListener listener)

  Adds an object to the list of those that wish to be informed when the library changes.

  Parameters:
    `listener` - a new listener to add to the list
