      • project

        public ProjCoordinate project​(double lplam,
                                      double lpphi,
                                      ProjCoordinate xy)
        Description copied from class: Projection
        Computes the projection of a given point (i.e. from geographics to projection space). This should be overridden for all projections.
        Overrides:
        project in class Projection
        Parameters:
        lplam - the geographic x ordinate (in radians)
        lpphi - the geographic y ordinatee (in radians)
        xy - the projected coordinate (in coordinate system units)
        Returns:
        the target coordinate
      • setW

        public void setW​(double w)
      • getW

        public double getW()
      • initialize

        public void initialize()
        Description copied from class: Projection
        Initialize the projection. This should be called after setting parameters and before using the projection. This is for performance reasons as initialization may be expensive.
        Overrides:
        initialize in class Projection
      • isConformal

        public boolean isConformal()
        Returns true if this projection is conformal
        Overrides:
        isConformal in class Projection
        Returns:
        true if this projection is conformal
      • equals

        public boolean equals​(java.lang.Object that)
        Description copied from class: Projection
        Represents quality between possible outputs of Projection.project(ProjCoordinate, ProjCoordinate). Subclasses of Projection should capture additional state that is used in the project method and delgate to base. Note: The name of the projection is not part of equality.
        Overrides:
        equals in class Projection
      • hashCode

        public int hashCode()
        Description copied from class: Projection
        Hash of those fields considered in Projection equalituy. Subclasses that override equality should override hashCode.
        Overrides:
        hashCode in class Projection
