TrackLayer
public TrackLayer(java.util.Collection<Track> tracks)
- Creates a new
TrackLayer
with the specified tracks
in its internal collection.
- Parameters:
tracks
- Collection of Tracks
to add to this layer's internal collection.
doDraw
protected abstract void doDraw(DrawContext dc,
TrackPointIterator trackPoints,
java.awt.Point pickPoint)
doPick
protected void doPick(DrawContext dc,
java.awt.Point pickPoint)
- Overrides:
doPick
in class AbstractLayer
doRender
protected void doRender(DrawContext dc)
- Specified by:
doRender
in class AbstractLayer
getBoundingSector
public Sector getBoundingSector()
getElevation
public double getElevation()
getLowerLimit
public int getLowerLimit()
getNumPoints
public int getNumPoints()
getTracks
public java.lang.Iterable<Track> getTracks()
- Returns the Iterable of Tracks currently in use by this layer.
If the caller has specified a custom Iterable via
setTrackIterable(java.lang.Iterable)
, this will returns a reference
to that Iterable. If the caller passed setTrackIterable
a null parameter,
or if setTrackIterable
has not been called, this returns a view of this layer's internal
collection of Tracks.
- Returns:
- Iterable of currently active Tracks.
getUpperLimit
public int getUpperLimit()
isOverrideElevation
public boolean isOverrideElevation()
iterator
public TrackPointIterator iterator()
setBoundingSector
public void setBoundingSector(Sector boundingSector)
setElevation
public void setElevation(double markerElevation)
setLowerLimit
public void setLowerLimit(int lowerLimit)
setOverrideElevation
public void setOverrideElevation(boolean overrideElevation)
setTrackIterable
public void setTrackIterable(java.lang.Iterable<Track> trackIterable)
- Overrides the collection of currently active Tracks with the specified
trackIterable
.
This layer will maintain a reference to trackIterable
strictly for picking and rendering.
This layer will not modify the Iterable reference. However, this will clear
the internal collection of Tracks, and will prevent any modification to its contents via
setTracks
.
If the specified trackIterable
is null, this layer will revert to maintaining its internal
collection.
- Parameters:
trackIterable
- Iterable to use instead of this layer's internal collection, or null to use this
layer's internal collection.
setTracks
public void setTracks(java.util.Collection<Track> tracks)
- Sets the specified
tracks
as this layer's internal collection.
If this layer's internal collection has been overriden with a call to setTrackIterable(java.lang.Iterable)
,
this will throw an exception.
- Parameters:
tracks
- List of Tracks to use.
- Throws:
java.lang.IllegalArgumentException
- If tracks
is null.
java.lang.IllegalStateException
- If a custom Iterable has been specified by a call to setTrackIterable
.
setUpperLimit
public void setUpperLimit(int upperLimit)
toString
public java.lang.String toString()
- Overrides:
toString
