- All Implemented Interfaces:
AxesSelector
public class WeightedAxesSelector extends java.lang.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.- Since:

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 javax.swing.JComboBox getWeightSelector()
Gets the combo box used to select weighting columns.- Returns:
- weight selector
-
getColumnSelectorPanel
public javax.swing.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 interfaceAxesSelector
- Returns:
- column selector panel
-
getColumnSelectors
public javax.swing.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 interfaceAxesSelector
- 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 interfaceAxesSelector
- 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 interfaceAxesSelector
-
addActionListener
public void addActionListener(java.awt.event.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 interfaceAxesSelector
- Parameters:
listener
- listener to add
-
removeActionListener
public void removeActionListener(java.awt.event.ActionListener listener)
Description copied from interface:AxesSelector
Removes a listener added byAxesSelector.addActionListener(java.awt.event.ActionListener)
.- Specified by:
removeActionListener
in interfaceAxesSelector
- Parameters:
listener
- listener to remove
-
getNdim
public int getNdim()
Description copied from interface:AxesSelector
Returns the number of columns in the table thatAxesSelector.getData()
will return.- Specified by:
getNdim
in interfaceAxesSelector
- 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 interfaceAxesSelector
- 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 dohashCode
too.- Specified by:
getData
in interfaceAxesSelector
- 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 interfaceAxesSelector
- 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 interfaceAxesSelector
- 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 interfaceAxesSelector
- 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 storenpoint
points, and itsPointStore.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'sAxesSelector.getData()
andAxesSelector.getErrorData()
methods.- Specified by:
createPointStore
in interfaceAxesSelector
- 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 interfaceAxesSelector
- 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
