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 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
