Method Detail

getHeader

public InstancesHeader getHeader()

Description copied from interface: InstanceStream

Gets the header of this stream. This is useful to know attributes and classes. InstancesHeader is an extension of weka.Instances.

Returns:

the header of this stream

estimatedRemainingInstances

public long estimatedRemainingInstances()

Description copied from interface: InstanceStream

Gets the estimated number of remaining instances in this stream

Returns:

the estimated number of instances to get from this stream

hasMoreInstances

public boolean hasMoreInstances()

Description copied from interface: InstanceStream

Gets whether this stream has more instances to output. This is useful when reading streams from files.

Returns:

true if this stream has more instances to output

isRestartable

public boolean isRestartable()

Description copied from interface: InstanceStream

Gets whether this stream can restart.

Returns:

true if this stream can restart

prepareForUseImpl

public 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.

Specified by:

prepareForUseImpl in class AbstractOptionHandler

Parameters:

monitor - the TaskMonitor to use

repository - the ObjectRepository to use

restart

public void restart()

Description copied from interface: InstanceStream

Restarts this stream. It must be similar to starting a new stream from scratch.

generateHeader

protected void generateHeader()

initKernels

protected void initKernels()

nextInstance

public weka.core.Instance nextInstance()

Description copied from interface: InstanceStream

Gets the next instance from this stream.

Returns:

the next instance of this stream

getGeneratingClusters

public Clustering getGeneratingClusters()

getMicroClustering

public Clustering getMicroClustering()

getDescription

public void getDescription(StringBuilder sb,
                  int indent)

TOOLS

Parameters:

sb - the stringbuilder to add the description

indent - the number of characters to indent

addClusterChangeListener

public void addClusterChangeListener(ClusterEventListener l)

Add a listener

removeClusterChangeListener

public void removeClusterChangeListener(ClusterEventListener l)

Remove a listener

fireClusterChange

protected void fireClusterChange(long timestamp,
                     String type,
                     String message)

Fire a ClusterChangeEvent to all registered listeners

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 AbstractOptionHandler

Returns:

the string with the purpose of this object

getParameterString

public String getParameterString()
