Method Detail

constructCopy

public Projection constructCopy()

Description copied from class: AbstractProjection

copy constructor - avoid clone !!

Specified by:

constructCopy in class AbstractProjection

Returns:

a copy of this Projection.

paramsToString

public String paramsToString()

Description copied from interface: Projection

String representation of the projection parameters.

Specified by:

paramsToString in interface Projection

Specified by:

paramsToString in class AbstractProjection

latLonToProj

public ProjectionPoint latLonToProj(LatLonPoint latlon)

Description copied from interface: Projection

Convert a LatLonPoint to projection coordinates.

projToLatLon

public LatLonPoint projToLatLon(ProjectionPoint ppt)

Description copied from interface: Projection

Convert projection coordinates to a LatLonPoint.

crossSeam

public boolean crossSeam(ProjectionPoint pt1,
                         ProjectionPoint pt2)

Description copied from interface: Projection

Does the line between these two points cross the projection "seam", which is a discontinuity in the function latlon <-> projection plane

Parameters:

pt1 - the line goes between these two points

pt2 - the line goes between these two points

Returns:

false if there is no seam, or the line does not cross it.

equals

public boolean equals(Object o)

Overrides:

equals in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object
