Method Detail

getPurposeString

public String getPurposeString()

Description copied from interface: OptionHandler

Gets the purpose of this object

Specified by:

getPurposeString in interface OptionHandler

Overrides:

getPurposeString in class WaveformGenerator

Returns:

the string with the purpose of this object

prepareForUseImpl

protected void prepareForUseImpl(TaskMonitor monitor,
                     ObjectRepository repository)

Description copied from class: AbstractOptionHandler

This method describes the implementation of how to prepare this object for use. All classes that extends this class have to implement prepareForUseImpl and not prepareForUse since prepareForUse calls prepareForUseImpl.

Overrides:

prepareForUseImpl in class WaveformGenerator

Parameters:

monitor - the TaskMonitor to use

repository - the ObjectRepository to use

nextInstance

public weka.core.Instance nextInstance()

Description copied from interface: InstanceStream

Gets the next instance from this stream.

Specified by:

nextInstance in interface InstanceStream

Overrides:

nextInstance in class WaveformGenerator

Returns:

the next instance of this stream

getDescription

public void getDescription(StringBuilder sb,
                  int indent)

Description copied from interface: MOAObject

Returns a string representation of this object. Used in AbstractMOAObject.toString to give a string representation of the object.

Specified by:

getDescription in interface MOAObject

Overrides:

getDescription in class WaveformGenerator

Parameters:

sb - the stringbuilder to add the description

indent - the number of characters to indent
