Constant Field Values

m_RelationNameLab

protected JLabel m_RelationNameLab

Displays the name of the relation

m_NumInstancesLab

protected JLabel m_NumInstancesLab

Displays the number of instances

m_NumAttributesLab

protected JLabel m_NumAttributesLab

Displays the number of attributes

m_sumOfWeightsLab

protected JLabel m_sumOfWeightsLab

Displays the sum of instance weights

m_Instances

protected weka.core.Instances m_Instances

The instances we're playing with

m_showZeroInstancesAsUnknown

protected boolean m_showZeroInstancesAsUnknown

Whether to display 0 or ? for the number of instances in cases where a dataset has only structure. Depending on where this panel is used from, the user may have loaded a dataset with no instances or a Loader that can read incrementally may be being used (in which case we don't know how many instances are in the dataset... yet).

Constructor Detail

InstancesSummaryPanel

public InstancesSummaryPanel()

Creates the instances panel with no initial instances.

Method Detail

setShowZeroInstancesAsUnknown

public void setShowZeroInstancesAsUnknown(boolean zeroAsUnknown)

Set whether to show zero instances as unknown (i.e. "?" rather than zero). This is useful if header information has been read and the instances themselves will be loaded incrementally.

Parameters:

zeroAsUnknown - true if zero instances will be displayed as "unknown", i.e. "?"

getShowZeroInstancesAsUnknown

public boolean getShowZeroInstancesAsUnknown()

Get whether to show zero instances as unknown (i.e. "?" rather than zero). This is useful if header information has been read and the instances themselves will be loaded incrementally.

Returns:

true if zero instances will be displayed as "unknown", i.e. "?"

setInstances

public void setInstances(weka.core.Instances inst)

Tells the panel to use a new set of instances.

Parameters:

inst - a set of Instances, null to unset

main

public static void main(String[] args)

Tests out the instance summary panel from the command line.

Parameters:

args - optional name of dataset to load
