Interface ContourPlot.Renderable

All Known Implementing Classes:

ContourPlot.Legend, ContourPlot.Lines, ContourPlot.Points, ContourPlot.Text, ContourPlot.Triangles

Enclosing class:

ContourPlot

public static interface ContourPlot.Renderable

Interface for an object that can be rendered by a ContourPlot.Renderer e.g. the ContourPlot.GenericRenderer. It is intended for objects that contain openGL resources such as a

invalid reference

VertexArray

for example. For this reason the interface extends the AutoCloseable interface for disposing of GL resources on

invalid reference

#close()

. Its state can be dirty (isDirty()) which means that the GL resources are not in sync with the object and implies that a call to the

invalid reference

#updateGL(boolean)

method is necessary before rendering. The

invalid reference

#initGL()

method has to be called once before the first rendering to allocate required GL resources.

Method Summary

Modifier and Type	Method	Description
boolean	intersects(Rectangle2D rect)	tests if this ContourPlot.Renderable intersects or contains the specified rectangle.
boolean	isDirty()	if true, indicates that a call to invalid reference #updateGL(boolean) is necessary to sync this objects GL resources to its current state.
default boolean	isHidden()	Indicates whether this Renderable is hidden i.e. will not be drawn.

Method Details

intersects

boolean intersects(Rectangle2D rect)

tests if this ContourPlot.Renderable intersects or contains the specified rectangle.

Parameters:

rect - rectangle to test

Returns:

true when intersecting

isHidden

default boolean isHidden()

Indicates whether this Renderable is hidden i.e. will not be drawn.

Returns:

true when hidden

isDirty

boolean isDirty()

if true, indicates that a call to

invalid reference

#updateGL(boolean)

is necessary to sync this objects GL resources to its current state.

Returns:

true if dirty
