Method Summary
 void addActionListener(ActionListener listener)
          Adds a listener which is notified when any of the selections made by this component changes.
 AxisEditor[] createAxisEditors()
          Constructs an array of AxisEditor objects suitable for modifying the axes which are defined by this selector.
 PointStore createPointStore(int npoint)
          Returns a PointStore suitable for storing coordinate and error information generated by the current state of this selector.
 JComponent getColumnSelectorPanel()
          Returns the panel which contains column selectors and any other UI components that the concrete subclass wants to place.
 JComboBox[] getColumnSelectors()
          Returns the array of combo boxes which are used to select column or other values.
 uk.ac.starlink.table.StarTable getData()
          Returns a StarTable which corresponds to the data in the columns selected by the current selections on this object.
 uk.ac.starlink.table.StarTable getErrorData()
          Returns a StarTable which corresponds to the error data defined by the current selections.

          Returns the error modes currently in force for this selector.
 uk.ac.starlink.table.StarTable getLabelData()
          Returns a StarTable whose single column contains a label for each point.
 int getNdim()
          Returns the number of columns in the table that getData() will return.
 void initialiseSelectors()
          Hint to set up the values of the column selectors to a sensible value.
 boolean isReady()
          Indicates whether this selector has enough state filled in to be able to specify some point data.

Method Detail

getColumnSelectorPanel

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

Returns:
column selector panel

getColumnSelectors

JComboBox[] getColumnSelectors()
Returns the array of combo boxes which are used to select column or other values.

Returns:
array of column selector combo boxes

setTable

void setTable(TopcatModel tcModel)
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.

Parameters:
tcModel - table for which selectors must be configured

initialiseSelectors

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


addActionListener

void addActionListener(ActionListener listener)
Adds a listener which is notified when any of the selections made by this component changes.

Parameters:
listener - listener to add

removeActionListener

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

Parameters:
listener - listener to remove

getNdim

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

Returns:
dimensionality

isReady

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

Returns:
true iff properly filled in

getData

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

Returns:
table containing the data from the current selection

getErrorData

uk.ac.starlink.table.StarTable getErrorData()
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 getData() about table equality - the same constraints apply.

Returns:
error data table

getLabelData

uk.ac.starlink.table.StarTable getLabelData()
Returns a StarTable whose single column contains a label for each point.

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

Returns:
label table

createAxisEditors

AxisEditor[] createAxisEditors()
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.

Returns:
array of new AxisEditors

createPointStore

PointStore createPointStore(int npoint)
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 getData() and getErrorData() methods.

Parameters:
npoint - number of points to store
Returns:
new point store

getErrorModes

uk.ac.starlink.ttools.plot.ErrorMode[] getErrorModes()
Returns the error modes currently in force for this selector.

Returns:
error mode array
