Method Detail

getDescription

public void getDescription(java.lang.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

Parameters:

sb - the stringbuilder to add the description

indent - the number of characters to indent

prepareForUseImpl

protected void prepareForUseImpl(TaskMonitor tm,
                                 ObjectRepository or)

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:

tm - the TaskMonitor to use

or - the ObjectRepository to use

getHeader

public InstancesHeader getHeader()

Description copied from interface: ExampleStream

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

Specified by:

getHeader in interface ExampleStream<Example<Instance>>

Returns:

the header of this stream

estimatedRemainingInstances

public long estimatedRemainingInstances()

Description copied from interface: ExampleStream

Gets the estimated number of remaining instances in this stream

Specified by:

estimatedRemainingInstances in interface ExampleStream<Example<Instance>>

Returns:

the estimated number of instances to get from this stream

hasMoreInstances

public boolean hasMoreInstances()

Description copied from interface: ExampleStream

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

Specified by:

hasMoreInstances in interface ExampleStream<Example<Instance>>

Returns:

true if this stream has more instances to output

nextInstance

public InstanceExample nextInstance()

Description copied from interface: ExampleStream

Gets the next example from this stream.

Specified by:

nextInstance in interface ExampleStream<Example<Instance>>

Returns:

the next example of this stream

isRestartable

public boolean isRestartable()

Description copied from interface: ExampleStream

Gets whether this stream can restart.

Specified by:

isRestartable in interface ExampleStream<Example<Instance>>

Returns:

true if this stream can restart

restart

public void restart()

Description copied from interface: ExampleStream

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

Specified by:

restart in interface ExampleStream<Example<Instance>>
