    • 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
    • projectInverse

      public ProjCoordinate projectInverse(double xyx, double xyy, ProjCoordinate lp)
      Description copied from class: Projection
      Computes the inverse projection of a given point (i.e. from projection space to geographics). This should be overridden for all projections.
      Overrides:
      projectInverse in class Projection
      Parameters:
      xyx - the projected x ordinate (in coordinate system units)
      xyy - the projected y ordinate (in coordinate system units)
      lp - the inverse-projected geographic coordinate (in radians)
      Returns:
      the target coordinate
    • hasInverse

      public boolean hasInverse()
      Description copied from class: Projection
      Tests whether this projection has an inverse. If this method returns true then the Projection.inverseProject(ProjCoordinate, ProjCoordinate) and Projection.inverseProjectRadians(ProjCoordinate, ProjCoordinate) methods will return meaningful results.
      Overrides:
      hasInverse in class Projection
      Returns:
      true if this projection has an inverse
    • equals

      public boolean equals(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
