Interface Globe2D

All Known Implementing Classes:

EarthFlat, FlatGlobe

public interface Globe2D

An interface for controlling aspects of a 2D Globe.

Method Summary

Modifier and Type	Method and Description
int	getOffset()
GeographicProjection	getProjection() Returns the geographic projection for this globe.
boolean	isContinuous() Indicates whether it makes sense to treat the associated projection as contiguous with itself.
void	setContinuous(boolean continuous) Specifies whether to treat the associated projection as contiguous with itself.
void	setOffset(int offset) Indicates an offset to apply to Cartesian points computed by this globe.
void	setProjection(GeographicProjection projection) Specifies the geographic projection for this globe.

Method Detail

getOffset

int getOffset()

getProjection

GeographicProjection getProjection()

Returns the geographic projection for this globe.

Returns:

The geographic projection for this globe.

isContinuous

boolean isContinuous()

Indicates whether it makes sense to treat the associated projection as contiguous with itself. If true, the scene controller will make the implementing globe appear to scroll continuously horizontally.

Returns:

true if it makes sense to treat the associated projection as continuous, otherwise false.

setContinuous

void setContinuous(boolean continuous)

Specifies whether to treat the associated projection as contiguous with itself. If true, the scene controller will make the implementing globe appear to scroll continuously horizontally. Calling this method overrides the associated projection's value for this field.

Parameters:

continuous - true if it makes sense to treat the associated projection as continuous, otherwise false.

GeographicProjection.isContinuous()

setOffset

void setOffset(int offset)

Indicates an offset to apply to Cartesian points computed by this globe. The offset is in units of globe widths, e.g., an offset of one indicates a Cartesian offset of the globe's width in meters.

Parameters:

offset - The offset to apply, in units of globe widths.

setProjection

void setProjection(GeographicProjection projection)

Specifies the geographic projection for this globe. The geographic projection converts geographic positions to Cartesian coordinates and back. Implementations of this interface define their default projection.

Parameters:

projection - The projection to apply to this globe.

Throws:

IllegalArgumentException - if the projection is null.
