Constructor Details

GenericRenderer

public GenericRenderer()

Method Details

addItemToRender

public ContourPlot.GenericRenderer<T> addItemToRender(T item)

Adds an item to this renderer's itemsToRender list. The renderer will take care of calling

invalid reference

Renderable#initGL()

during its

invalid reference

#render(int, int, int, int)

method and will as well call

invalid reference

Renderable#updateGL(boolean)

if ContourPlot.Renderable.isDirty().

Parameters:

item - to add

Returns:

this for chaining

removeItemToRender

public boolean removeItemToRender(T item)

Removes an item from this renderer's itemsToRender list.

Parameters:

item - to remove

Returns:

true when successfully removed, else false (e.g. when not contained in list)

isEnabled

public boolean isEnabled()

Description copied from interface: ContourPlot.Renderer

Whether this renderer is enabled or not. By default a renderer is enabled and will render upon

invalid reference

#render(int, int, int, int)

or

invalid reference

#renderSVG(org.w3c.dom.Document, org.w3c.dom.Element, int, int)

. When disabled those methods return right away and will not render anything.

Specified by:

isEnabled in interface ContourPlot.Renderer

Returns:

true when active

getItemsToRender

public LinkedList<T> getItemsToRender()

Returns:

the list of items to render.

setView

public void setView(Rectangle2D view)

Description copied from interface: ContourPlot.AdaptableView

Sets the view rectangle that is the range of coordinates to be projected onto the view port.

For example when setting a view rectangle of (x=-1,y=-1,w=2,h=2) given a viewport of size (w=100,h=100), then a point with coordinates (x=0,y=0) will be projected to (x=50,y=50) on the viewport. A point with coordinates (x=-1,y=-1) will be projected to (x=0,y=0).

When setting the view rectangle to null, then no projection is happening and the coordinates are mapped directly to view port coordinates. E.g. coordinates (40,40) will be (40,40) on the viewport, as if the view rectangles size was coupled to the viewport size.

Specified by:

setView in interface ContourPlot.AdaptableView

Parameters:

view - the view rectangle (can be null)
