Class WeightedAxesSelector

java.lang.Object
  uk.ac.starlink.topcat.plot.WeightedAxesSelector

All Implemented Interfaces:

AxesSelector

public class WeightedAxesSelector
extends Object
implements AxesSelector

AxesSelector implementation which adds a weighting axis to the basic ones. The output is the same as that of the supplied base selector, but if weighting is in effect an additional weighting column is added.

Constructor Detail

WeightedAxesSelector

public WeightedAxesSelector(AxesSelector baseSelector)

Constructor.

Parameters:

baseSelector - selector without weighting on which this is based

Method Detail

enableWeights

public void enableWeights(boolean weightEnabled)

Sets whether the weighting selector is visible, and also whether any selection in it affects the output of this selector.

Parameters:

weightEnabled - true iff weighting is enabled

getWeightSelector

public JComboBox getWeightSelector()

Gets the combo box used to select weighting columns.

Returns:

weight selector

getColumnSelectorPanel

public JComponent getColumnSelectorPanel()

Description copied from interface: AxesSelector

Returns the panel which contains column selectors and any other UI components that the concrete subclass wants to place.

Specified by:

getColumnSelectorPanel in interface AxesSelector

Returns:

column selector panel

getColumnSelectors

public JComboBox[] getColumnSelectors()

Description copied from interface: AxesSelector

Returns the array of combo boxes which are used to select column or other values.

Specified by:

getColumnSelectors in interface AxesSelector

Returns:

array of column selector combo boxes

setTable

public void setTable(TopcatModel tcModel)

Description copied from interface: AxesSelector

Set up column selectors correctly for the given model. This will involve setting the column selector models appropriately. If the submitted table is null, then the selector models should be unselected.

Specified by:

setTable in interface AxesSelector

Parameters:

tcModel - table for which selectors must be configured

initialiseSelectors

public void initialiseSelectors()

Description copied from interface: AxesSelector

Hint to set up the values of the column selectors to a sensible value. An implementation which does nothing is legal.

Specified by:

initialiseSelectors in interface AxesSelector

addActionListener

public void addActionListener(ActionListener listener)

Description copied from interface: AxesSelector

Adds a listener which is notified when any of the selections made by this component changes.

Specified by:

addActionListener in interface AxesSelector

Parameters:

listener - listener to add

removeActionListener

public void removeActionListener(ActionListener listener)

Description copied from interface: AxesSelector

Removes a listener added by AxesSelector.addActionListener(java.awt.event.ActionListener).

Specified by:

removeActionListener in interface AxesSelector

Parameters:

listener - listener to remove

getNdim

public int getNdim()

Description copied from interface: AxesSelector

Returns the number of columns in the table that AxesSelector.getData() will return.

Specified by:

getNdim in interface AxesSelector

Returns:

dimensionality

isReady

public boolean isReady()

Description copied from interface: AxesSelector

Indicates whether this selector has enough state filled in to be able to specify some point data.

Specified by:

isReady in interface AxesSelector

Returns:

true iff properly filled in

getData

public uk.ac.starlink.table.StarTable getData()

Description copied from interface: AxesSelector

Returns a StarTable which corresponds to the data in the columns selected by the current selections on this object.

Note: for performance reasons, it is imperative that two tables returned from this method must match according to the Object.equals(java.lang.Object) method if they are known to contain the same cell data (i.e. if the state of this selector has not changed in the mean time). Don't forget to do hashCode too.

Specified by:

getData in interface AxesSelector

Returns:

table containing the data from the current selection

getErrorData

public uk.ac.starlink.table.StarTable getErrorData()

Description copied from interface: AxesSelector

Returns a StarTable which corresponds to the error data defined by the current selections. The details of how the table columns are laid out are down to the concrete subclass.

See the notes in AxesSelector.getData() about table equality - the same constraints apply.

Specified by:

getErrorData in interface AxesSelector

Returns:

error data table

getLabelData

public uk.ac.starlink.table.StarTable getLabelData()

Description copied from interface: AxesSelector

Returns a StarTable whose single column contains a label for each point.

See the notes in AxesSelector.getData() about table equality - the same constraints apply.

Specified by:

getLabelData in interface AxesSelector

Returns:

label table

createAxisEditors

public AxisEditor[] createAxisEditors()

Description copied from interface: AxesSelector

Constructs an array of AxisEditor objects suitable for modifying the axes which are defined by this selector. The number of them is often, but not necessarily, the same as the dimensionality of this selector.

Specified by:

createAxisEditors in interface AxesSelector

Returns:

array of new AxisEditors

createPointStore

public PointStore createPointStore(int npoint)

Description copied from interface: AxesSelector

Returns a PointStore suitable for storing coordinate and error information generated by the current state of this selector. The store will have to store npoint points, and its PointStore.storePoint(java.lang.Object[], java.lang.Object[], java.lang.String) method will be called with the result of acquiring rows from the tables got from this selector's AxesSelector.getData() and AxesSelector.getErrorData() methods.

Specified by:

createPointStore in interface AxesSelector

Parameters:

npoint - number of points to store

Returns:

new point store

getErrorModes

public uk.ac.starlink.ttools.plot.ErrorMode[] getErrorModes()

Description copied from interface: AxesSelector

Returns the error modes currently in force for this selector.

Specified by:

getErrorModes in interface AxesSelector

Returns:

error mode array

hasWeights

public boolean hasWeights()

Indicates whether non-unit weighting is in effect.

Returns:

if false, every element of the weighting column will be unity
