LuciadLightspeedClass TLspIsTouchedQuery

java.lang.Object

com.luciad.view.lightspeed.query.ALspPaintQuery<Boolean>

com.luciad.view.lightspeed.query.TLspIsTouchedQuery

public class TLspIsTouchedQuery
extends ALspPaintQuery<Boolean>

Query to determine whether an object is touched.

If this query is used for an object that is currently not painted (ex. because it is outside the view) then this query determines whether the object would have been touched if it were painted.

The touched(com.luciad.view.lightspeed.layer.ALspWorldTouchInfo) methods may be called multiple times if the object is touched at multiple points. This implementation only keeps track of the first touched point. You can override this class if you want to handle all touched points.

Since:

2012.0

Constructor Detail

TLspIsTouchedQuery

public TLspIsTouchedQuery(Object aObject,
                          TLspPaintRepresentation aPaintRepresentation,
                          ILcdPoint aViewPoint,
                          double aSensitivity)

Creates a new is touched query.

Parameters:

aObject - the object that should be tested

aPaintRepresentation - the paint representation

aViewPoint - the view point

aSensitivity - the sensitivity

TLspIsTouchedQuery

public TLspIsTouchedQuery(TLspLabelID aLabel,
                          ILcdPoint aViewPoint,
                          double aSensitivity)

Creates a new is touched query for a label.

Parameters:

aLabel - the label that should be tested

aViewPoint - the view point

aSensitivity - the sensitivity

TLspIsTouchedQuery

public TLspIsTouchedQuery(TLspLabelID aLabel,
                          ILcdPoint aViewPoint,
                          double aSensitivity,
                          ALspLabelLocation aLabelLocation)

Creates a new is touched query for a label, for the given location. If this location is null, the label location is retrieved from the ILspLabelPlacer instead.

Parameters:

aLabel - the label that should be tested

aViewPoint - the view point

Method Detail

getObject

public Object getObject()

Returns the object that should be queried.

Returns:

the object

getLabel

public TLspLabelID getLabel()

Returns the label that should be queried.

Returns:

the label

getLabelLocation

public ALspLabelLocation getLabelLocation()

Returns the label location for the label that should be queried.

Returns:

the label location. Can be null.

getPaintRepresentation

public TLspPaintRepresentation getPaintRepresentation()

Returns the paint representation that should be queried.

Returns:

the paint representation

getViewPoint

public ILcdPoint getViewPoint()

Returns the view point that should be queried.

Returns:

the view point

getSensitivity

public double getSensitivity()

Returns the sensitivity in pixels.

Returns:

the sensitivity

getResult

public Boolean getResult()

Returns whether the object is touched.

Specified by:

getResult in class ALspPaintQuery<Boolean>

Returns:

true if the object is touched, false otherwise

touched

public boolean touched(ALspWorldTouchInfo aTouchInfo)

Returns:

true if the query should continue, false if it should stop

touched

public boolean touched(ALspViewTouchInfo aTouchInfo)

Called if the object is touched at a point in view coordinates.

Parameters:

aTouchInfo - the touch info

Returns:

true if the query should continue, false if it should stop

isTouched

public boolean isTouched()

Returns whether the object is touched.

Returns:

true if the object is touched, false otherwise

getTouchInfo

public ALspTouchInfo getTouchInfo()

Returns the touch info if the object is touched.

Returns:

the touch info or null
