public interface CircularRendererContext
A context providing information for rendering sequences into circular coordinate systems.
Note: All angles are measured in radians, using the normal Java graphics concepts of angles.
Method Summary | |
---|---|
double |
getAngle(int indx)
Return the angle for an index into a sequence. |
FeatureHolder |
getFeatures()
The features to render. |
int |
getIndex(double angle)
Calculate the position in the sequence relating to the angle. |
double |
getOffset()
Get the angle through which the origin of the sequence is rotated through. |
double |
getRadius()
Get the current radius at which data should be rendered. |
SymbolList |
getSymbols()
The SymbolList that is currently rendered by this context. |
Method Detail |

double getOffset()
This is equivalent to adding the offset to all calculated angles.
double getAngle(int indx)
indx
- the sequence offset
int getIndex(double angle)
angle
- the angle arround the circle
double getRadius()
SymbolList getSymbols()
FeatureHolder getFeatures()
