getPurposeString
public String getPurposeString()
Description copied from class:AbstractOptionHandler
Dictionary with option texts and objects- Specified by:
getPurposeString
in interfaceOptionHandler
- Overrides:
getPurposeString
in classAbstractOptionHandler
- 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 implementprepareForUseImpl
and notprepareForUse
sinceprepareForUse
callsprepareForUseImpl
.- Specified by:
prepareForUseImpl
in classAbstractOptionHandler
- Parameters:
monitor
- the TaskMonitor to userepository
- the ObjectRepository to use
-
estimatedRemainingInstances
public long estimatedRemainingInstances()
Description copied from interface:ExampleStream
Gets the estimated number of remaining instances in this stream- Specified by:
estimatedRemainingInstances
in interfaceExampleStream<Example<Instance>>
- Returns:
- the estimated number of instances to get from this stream
-
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 interfaceExampleStream<Example<Instance>>
- Returns:
- the header of 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 interfaceExampleStream<Example<Instance>>
- Returns:
- true if this stream has more instances to output
-
isRestartable
public boolean isRestartable()
Description copied from interface:ExampleStream
Gets whether this stream can restart.- Specified by:
isRestartable
in interfaceExampleStream<Example<Instance>>
- Returns:
- true if this stream can restart
-
nextInstance
public InstanceExample nextInstance()
Description copied from interface:ExampleStream
Gets the next example from this stream.- Specified by:
nextInstance
in interfaceExampleStream<Example<Instance>>
- Returns:
- the next example of this stream
-
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 interfaceExampleStream<Example<Instance>>
-
getDescription
public void getDescription(StringBuilder sb, int indent)
Description copied from interface:MOAObject
Returns a string representation of this object. Used inAbstractMOAObject.toString
to give a string representation of the object.- Specified by:
getDescription
in interfaceMOAObject
- Parameters:
sb
- the stringbuilder to add the descriptionindent
- the number of characters to indent
-
defineImmutableCapabilities
public ImmutableCapabilities defineImmutableCapabilities()
Description copied from interface:CapabilitiesHandler
Defines the set of capabilities the object has. Should be overridden if the object's capabilities do not change.- Specified by:
defineImmutableCapabilities
in interfaceCapabilitiesHandler
- Specified by:
defineImmutableCapabilities
in interfaceExampleStream<Example<Instance>>
- Returns:
- The capabilities of the object.
