Class DefaultEngineeringCRS

All Implemented Interfaces:
Serializable, Formattable, Deprecable, Lenient­Comparable, Printable, Coordinate­Reference­System, Engineering­CRS, Single­CRS, Identified­Object, Reference­System

public class DefaultEngineeringCRS extends AbstractCRS implements EngineeringCRS
A 1-, 2- or 3-dimensional contextually local coordinate reference system. It can be divided into two broad categories:
  • earth-fixed systems applied to engineering activities on or near the surface of the earth;
  • CRSs on moving platforms such as road vehicles, vessels, aircraft, or spacecraft.

Used with datum type: Engineering.
Used with coordinate system types: Affine, Cartesian, Cylindrical, Linear. Polar, Spherical or User Defined.

Immutability and thread safety

This class is immutable and thus thread-safe if the property values (not necessarily the map itself), the coordinate system and the datum instances given to the constructor are also immutable. Unless otherwise noted in the javadoc, this condition holds if all components were created using only SIS factories and static constants.
Since:
0.4

    • castOrCopy

      public static DefaultEngineeringCRS castOrCopy(EngineeringCRS object)
      Returns a SIS coordinate reference system implementation with the same values as the given arbitrary implementation. If the given object is null, then this method returns null. Otherwise if the given object is already a SIS implementation, then the given object is returned unchanged. Otherwise a new SIS implementation is created and initialized to the attribute values of the given object.
      Parameters:
      object - the object to get as a SIS implementation, or null if none.
      Returns:
      a SIS implementation containing the values of the given object (may be the given object itself), or null if the argument was null.
    • getInterface

      public Class<? extends EngineeringCRS> getInterface()
      Returns the GeoAPI interface implemented by this class. The SIS implementation returns Engineering­CRS​.class.

      Note for implementers

      Subclasses usually do not need to override this method since GeoAPI does not define Engineering­CRS sub-interface. Overriding possibility is left mostly for implementers who wish to extend GeoAPI with their own set of interfaces.
      Returns:
      Engineering­CRS​.class or a user-defined sub-interface.
    • getDatum

      public EngineeringDatum getDatum()
      Returns the identification of the origin of this engineering (or local) CRS. This property may be null if this CRS is related to an object identified only by a datum ensemble.
      Specified by:
      get­Datum in interface Engineering­CRS
      Specified by:
      get­Datum in interface Single­CRS
      Returns:
      the engineering datum, or null if this CRS is related to an object identified only by a datum ensemble.
    • getDatumEnsemble

      public DefaultDatumEnsemble<EngineeringDatum> getDatumEnsemble()
      Returns a collection of datums which, for low accuracy requirements, may be considered to be insignificantly different from each other. This property may be null if this CRS is related to an object identified only by a single datum.
      Warning: in a future SIS version, the return type may be changed to the org​.opengis​.referencing​.datum​.Datum­Ensemble interface. This change is pending GeoAPI revision.
      Returns:
      the datum ensemble, or null if this CRS is related to an object identified only by a single datum.

    • forConvention

      public DefaultEngineeringCRS forConvention(AxesConvention convention)
      Returns a CRS equivalent to this one but with axes rearranged according the given convention. If this CRS is already compatible with the given convention, then this method returns this.
      Overrides:
      for­Convention in class Abstract­CRS
      Parameters:
      convention - the axes convention for which a coordinate reference system is desired.
      Returns:
      a coordinate reference system compatible with the given convention (may be this).

    • formatTo

      protected String formatTo(Formatter formatter)
      Formats this CRS as a Well Known Text Engineering­CRS[…] element.
      Overrides:
      format­To in class Abstract­CRS
      Parameters:
      formatter - the formatter where to format the inner content of this WKT element.
      Returns:
      "Engineering­CRS" (WKT 2) or "Local_CS" (WKT 1).
