Field Detail

m_Owner

protected SpreadSheetRowPanel m_Owner

the owner of this detector.

Constructor Detail

SpreadSheetRowPointHitDetector

public SpreadSheetRowPointHitDetector(SpreadSheetRowPanel owner)

Initializes the hit detector.

Parameters:

owner - the panel that uses this detector

Method Detail

globalInfo

public String globalInfo()

Returns a string describing the object.

Specified by:

globalInfo in interface GlobalInfoSupporter

Specified by:

globalInfo in class AbstractOptionHandler

Returns:

a description suitable for displaying in the gui

getOwner

public SpreadSheetRowPanel getOwner()

Returns the owner.

Returns:

the owning panel

findEnclosingAttributeIndices

protected int[] findEnclosingAttributeIndices(SpreadSheetRow row,
                                              double x)

Determines the enclosing attribute indices for the given x value. If the given x happens to be an exact point, then this points will be stored at index 0. If no index could be determined, then -1 will be stored.

Parameters:

row - the underlying row

x - the x on the plot

Returns:

the indices

findClosestAttributeIndex

protected int findClosestAttributeIndex(SpreadSheetRow row,
                                        double x)

Returns the closest attribute index for the given x.

Parameters:

row - the underlying Row

x - the x to get the index for

Returns:

the index

findSpreadSheetRowPoint

protected SpreadSheetRowPoint findSpreadSheetRowPoint(SpreadSheetRow inst,
                                                      int index)

Returns the Row point at the specified position.

Parameters:

inst - the Row data structure to search

index - the attribute index (original dataset)

Returns:

the RowPoint, null if not found

isHit

protected List<SpreadSheetRowPoint> isHit(MouseEvent e)

Checks for a hit.

For calculating distance between point and line, see here

Specified by:

isHit in class AbstractHitDetector<List<SpreadSheetRowPoint>,String>

Parameters:

e - the MouseEvent (for coordinates)

Returns:

the associated object with the hit, otherwise null

processHit

protected String processHit(MouseEvent e,
                            List<SpreadSheetRowPoint> hit)

Performs the action when a hit is detected.

Specified by:

processHit in class AbstractHitDetector<List<SpreadSheetRowPoint>,String>

Parameters:

e - the MouseEvent (for coordinates)

hit - the object that got determined by the hit

Returns:

the generated appendix for the tiptext

cleanUp

public void cleanUp()

Cleans up data structures, frees up memory.

Specified by:

cleanUp in interface CleanUpHandler

Overrides:

cleanUp in class AbstractHitDetector<List<SpreadSheetRowPoint>,String>
