sim.portrayal.grid.HexaSparseGridPortrayal2D
- All Implemented Interfaces:
- java.io.Serializable, Portrayal, Portrayal2D
public class HexaSparseGridPortrayal2D
- extends SparseGridPortrayal2D
Portrayal for hexagonal grids (each cell has six equally-distanced neighbors). It can draw
either continuous and descrete sparse fields.
The 'location' passed
into the DrawInfo2D handed to the SimplePortryal2D is an Int2D.

Field Summary |
static double |
HEXAGONAL_RATIO
The ratio of the width of a hexagon to its height: 1 / Sin(60 degrees), otherwise known as 2 / Sqrt(3) |
Method Summary |
java.lang.Object |
getClipLocation(DrawInfo2D fieldPortrayalInfo)
Returns an object representing the location in the field of the origin of the clip of the DrawInfo2D. |
java.awt.geom.Point2D.Double |
getLocationPosition(java.lang.Object location,
DrawInfo2D info)
Returns the position on-screen of the provided location in the underlying field. |
java.lang.Object |
getPositionLocation(java.awt.geom.Point2D.Double position,
DrawInfo2D info)
Returns the Location, in the parlance of the underlying Field, of the given position. |
Double2D |
getScale(DrawInfo2D info)
Returns the width and height, in pixels, of 1.0 x 1.0 units in the underlying field. |
protected void |
hitOrDraw(java.awt.Graphics2D graphics,
DrawInfo2D info,
Bag putInHere)
Instead of overriding the draw and hitObjects methods, you can optionally override
this method to provide both the draw(...) and hitObjects(...)
functionality in a single method, as it's common that these two methods have nearly
identical code. |
void |
setObjectPosition(java.lang.Object object,
java.awt.geom.Point2D.Double position,
DrawInfo2D fieldPortrayalInfo)
Moves (or tries to move) the object to an internal location equivalent to the given position on-screen of the
provided object, assuming that the object exists within the underlying field and that this
location is acceptable. |

setObjectPosition
public void setObjectPosition(java.lang.Object object,
java.awt.geom.Point2D.Double position,
DrawInfo2D fieldPortrayalInfo)
- Description copied from class:
FieldPortrayal2D
- Moves (or tries to move) the object to an internal location equivalent to the given position on-screen of the
provided object, assuming that the object exists within the underlying field and that this
location is acceptable. Optionally overridable. The default implementation does nothing.
- Overrides:
setObjectPosition
in class SparseGridPortrayal2D
getClipLocation
public java.lang.Object getClipLocation(DrawInfo2D fieldPortrayalInfo)
- Description copied from class:
FieldPortrayal2D
- Returns an object representing the location in the field of the origin of the clip of the DrawInfo2D.
This method calls getPositionLocation, which may or may not be implemented by the FieldPortrayal2D.
- Overrides:
getClipLocation
in class SparseGridPortrayal2D
getScale
public Double2D getScale(DrawInfo2D info)
- Description copied from class:
FieldPortrayal2D
- Returns the width and height, in pixels, of 1.0 x 1.0 units in the underlying field.
Optionally overridable. The default version thows an error if called.
- Overrides:
getScale
in class SparseGridPortrayal2D
getPositionLocation
public java.lang.Object getPositionLocation(java.awt.geom.Point2D.Double position,
DrawInfo2D info)
- Description copied from class:
FieldPortrayal2D
- Returns the Location, in the parlance of the underlying Field, of the given position.
If there is no such Location, then null is returned. Optionally overridable.
By default null is returned.
- Overrides:
getPositionLocation
in class SparseGridPortrayal2D
getLocationPosition
public java.awt.geom.Point2D.Double getLocationPosition(java.lang.Object location,
DrawInfo2D info)
- Description copied from class:
FieldPortrayal2D
- Returns the position on-screen of the provided location in the underlying field. Negative positions are acceptable.
If null is returned, then the portrayal is unable to perform the requested action on the given location.
Optionally overridable. The default implementation returns null.
- Overrides:
getLocationPosition
in class SparseGridPortrayal2D
hitOrDraw
protected void hitOrDraw(java.awt.Graphics2D graphics,
DrawInfo2D info,
Bag putInHere)
- Description copied from class:
FieldPortrayal2D
- Instead of overriding the draw and hitObjects methods, you can optionally override
this method to provide both the draw(...) and hitObjects(...)
functionality in a single method, as it's common that these two methods have nearly
identical code. You should test which operation to do
based on whether or not graphics is null (if it is, you're hitting, else you're drawing).
- Overrides:
hitOrDraw
in class SparseGridPortrayal2D
