public abstract class ALcdObliqueCylindrical extends ALcdProjection implements ILcdObliqueCylindrical, Cloneable
An ALcdObliqueCylindrical is an ILcdProjection that is obtained by wrapping a cylinder around the globe.

An ALcdObliqueCylindrical has a standardParallel, which is determined by a latitude. For a tangent cylindrical projection, the standard parallel is the equator, i.e., aLat == 0.0

An ALcdObliqueCylindrical has a centralMeridian, which is determined by a longitude. The central meridian determines the position of the origin, which is always on the equator.

An ALcdObliqueCylindrical has an azimuth. The azimuth (east of north) determines the central line.

    • loadProperties

      public void loadProperties(String aPrefix, Properties aProperty) throws IllegalArgumentException
      Loads the 3 properties of an ALcdObliqueCylindrical: the centralMeridian, the azimuth and the standardParallel. This method will, given aPrefix, analyze the aProperties object to set the properties of this ALcdObliqueCylindrical. The values of following keys are retrieved:
      • <aPrefix><the name of the class that extends this abstract class>.centralMeridian
      • <aPrefix><the name of the class that extends this abstract class>.standardParallel
      • <aPrefix><the name of the class that extends this abstract class>.azimuth
      Specified by:
      loadProperties in interface ILcdProjection
      Parameters:
      aPrefix - prefix of the property names.
      aProperty - Properties object containing the serialized properties.
      Throws:
      IllegalArgumentException - if the projection cannot be created.

    • writePropertiesSFCT

      public void writePropertiesSFCT(String aPrefix, Properties aPropertySFCT)
      Writes the 3 properties of an ALcdObliqueCylindrical: the centralMeridian, the azimuth and the standardParallel. This method will, given aPrefix, store the properties of this ALcdObliqueCylindrical into the aProperties object. The values of following keys are stored:
      • <aPrefix><the name of the class that extends this abstract class>.centralMeridian
      • <aPrefix><the name of the class that extends this abstract class>.standardParallel
      • <aPrefix><the name of the class that extends this abstract class>.azimuth

      writePropertiesSFCT in interface ILcdProjection
      Parameters:
      aPrefix - prefix for the property names.
      aPropertySFCT - Properties object to store the serialized properties by side effect.

    • calculateCachedValues

      protected void calculateCachedValues()
      Constants based on the longitude, latitude, standard parallel, and azimuth of the projection don't have to be recalculated every time a method is called. They only have to be calculated when the projection properties change. Within the methods the precalculated values then can be used in order to gain efficiency.

    • hashCode

      public int hashCode()
      Overrides:
      hashCode in class Object

    • equals

      public boolean equals(Object aObject)
      Description copied from interface: ILcdProjection
      Checks if this ILcdProjection equals some other Object.
      Specified by:

      Parameters:
      aObject - Object to compare with.
      Returns:
      true if the Object is an instance of the same ILcdProjection class and having the same projection properties, false otherwise.
