m_Classifiers

protected Classifier[] m_Classifiers
Array for storing the generated base classifiers.

Constructor Detail

MultipleClassifiersCombiner

public MultipleClassifiersCombiner()
Method Detail

listOptions

public java.util.Enumeration listOptions()
Returns an enumeration describing the available options

Specified by:
listOptions in interface OptionHandler
Overrides:
listOptions in class Classifier
Returns:
an enumeration of all the available options

setOptions

public void setOptions(java.lang.String[] options)
                throws java.lang.Exception
Parses a given list of options. Valid options are:

-B classifierstring
Classifierstring should contain the full class name of a scheme included for selection followed by options to the classifier (required, option should be used once for each classifier).

Specified by:
setOptions in interface OptionHandler
Overrides:
setOptions in class Classifier
Parameters:
options - the list of options as an array of strings
Throws:
java.lang.Exception - if an option is not supported

getOptions

public java.lang.String[] getOptions()
Gets the current settings of the Classifier.

Specified by:
getOptions in interface OptionHandler
Overrides:
getOptions in class Classifier
Returns:
an array of strings suitable for passing to setOptions

classifiersTipText

public java.lang.String classifiersTipText()
Returns the tip text for this property

Returns:
tip text for this property suitable for displaying in the explorer/experimenter gui

setClassifiers

public void setClassifiers(Classifier[] classifiers)
Sets the list of possible classifers to choose from.

Parameters:
classifiers - an array of classifiers with all options set.

getClassifiers

public Classifier[] getClassifiers()
Gets the list of possible classifers to choose from.

Returns:
the array of Classifiers

getClassifier

public Classifier getClassifier(int index)
Gets a single classifier from the set of available classifiers.

Parameters:
index - the index of the classifier wanted
Returns:
the Classifier

getClassifierSpec

protected java.lang.String getClassifierSpec(int index)
Gets the classifier specification string, which contains the class name of the classifier and any options to the classifier

Parameters:
index - the index of the classifier string to retrieve, starting from 0.
Returns:
the classifier string, or the empty string if no classifier has been assigned (or the index given is out of range).
