Interface CircularRendererContext

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 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

getOffset

public 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

public 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

public 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

public double getRadius()

Get the current radius at which data should be rendered.

Returns:

the radius

getSymbols

public SymbolList getSymbols()

The SymbolList that is currently rendered by this context.

Returns:

the Sequence value

getFeatures

public FeatureHolder getFeatures()

The features to render.

Returns:

a FeatureHolder with the Features to render
