All Known Implementing Classes:
SubCircularRendererContext

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 Detail

getOffset

double getOffset()
Get the angle through which the origin of the sequence is rotated through.

This is equivalent to adding the offset to all calculated angles.

Returns:
the rotation offset

getAngle

double getAngle(int indx)
Return the angle for an index into a sequence.

Parameters:
indx - the sequence offset
Returns:
the angle this offset is to be rendered to

getIndex

int getIndex(double angle)
Calculate the position in the sequence relating to the angle.

Parameters:
angle - the angle arround the circle
Returns:
the index of the symbol rendered at that angle

getRadius

double getRadius()
Get the current radius at which data should be rendered.

Returns:
the radius

getSymbols

SymbolList getSymbols()
The SymbolList that is currently rendered by this context.

Returns:
the Sequence value

getFeatures

FeatureHolder getFeatures()
The features to render.

Returns:
a FeatureHolder with the Features to render
