Class DefaultEngineeringCRS

    • Field Detail

      • wildcard

        protected boolean wildcard
        Marks the CRS as a wildcard one. Wildcard CRS will transform to any other CRS with the identity transform
      • CARTESIAN_2D

        public static final DefaultEngineeringCRS CARTESIAN_2D
        A two-dimensional cartesian coordinate reference system with x, y axis in metres. By default, this CRS has no transformation path to any other CRS (i.e. a map using this CS can't be reprojected to a geographic coordinate reference system for example).
      • CARTESIAN_3D

        public static final DefaultEngineeringCRS CARTESIAN_3D
        A three-dimensional cartesian coordinate reference system with x, y, z axis in metres. By default, this CRS has no transformation path to any other CRS (i.e. a map using this CS can't be reprojected to a geographic coordinate reference system for example).
      • GENERIC_2D

        public static final DefaultEngineeringCRS GENERIC_2D
        A two-dimensional wildcard coordinate system with x, y axis in metres. At the difference of CARTESIAN_2D, this coordinate system is treated specially by the default coordinate operation factory with loose transformation rules: if no transformation path were found (for example through a derived CRS), then the transformation from this CRS to any CRS with a compatible number of dimensions is assumed to be the identity transform. This CRS is usefull as a kind of wildcard when no CRS were explicitly specified.
      • GENERIC_3D

        public static final DefaultEngineeringCRS GENERIC_3D
        A three-dimensional wildcard coordinate system with x, y, z axis in metres. At the difference of CARTESIAN_3D, this coordinate system is treated specially by the default coordinate operation factory with loose transformation rules: if no transformation path were found (for example through a derived CRS), then the transformation from this CRS to any CRS with a compatible number of dimensions is assumed to be the identity transform.

    • Constructor Detail

      • DefaultEngineeringCRS

        public DefaultEngineeringCRS​(EngineeringCRS crs)
        Constructs a new enginnering CRS with the same values than the specified one. This copy constructor provides a way to wrap an arbitrary implementation into a Geotools one or a user-defined one (as a subclass), usually in order to leverage some implementation-specific API. This constructor performs a shallow copy, i.e. the properties are not cloned.
        Parameters:
        crs - The CRS to copy.
        Since:
        2.2
      • DefaultEngineeringCRS

        public DefaultEngineeringCRS​(String name,
                                     EngineeringDatum datum,
                                     CoordinateSystem cs)
        Constructs an engineering CRS from a name.
        Parameters:
        name - The name.
        datum - The datum.
        cs - The coordinate system.
      • DefaultEngineeringCRS

        public DefaultEngineeringCRS​(Map<String,​?> properties,
                                     EngineeringDatum datum,
                                     CoordinateSystem cs)
        Constructs an engineering CRS from a set of properties. The properties are given unchanged to the super-class constructor.
        Parameters:
        properties - Set of properties. Should contains at least "name".
        datum - The datum.
        cs - The coordinate system.
      • DefaultEngineeringCRS

        public DefaultEngineeringCRS​(Map<String,​?> properties,
                                     EngineeringDatum datum,
                                     CoordinateSystem cs,
                                     boolean wildcard)
        Constructs an engineering CRS from a set of properties. The properties are given unchanged to the super-class constructor.
        Parameters:
        properties - Set of properties. Should contains at least "name".
        datum - The datum.
        cs - The coordinate system.
        wildcard - When true the CRS will transform to any other CRS with the identity transform
    • Method Detail

      • hashCode

        public int hashCode()
        Returns a hash value for this derived CRS.
        Overrides:
        hashCode in class AbstractSingleCRS
        Returns:
        The hash code value. This value doesn't need to be the same in past or future versions of this class.
      • equals

        public boolean equals​(AbstractIdentifiedObject object,
                              boolean compareMetadata)
        Compares the specified object to this CRS for equality. This method is overridden because, otherwise, CARTESIAN_xD and GENERIC_xD would be considered equals when metadata are ignored.
        Overrides:
        equals in class AbstractSingleCRS
        Parameters:
        object - The object to compare to this.
        compareMetadata - true for performing a strict comparaison, or false for comparing only properties relevant to transformations.
        Returns:
        true if both objects are equal.
      • isWildcard

        public boolean isWildcard()
        Returns true if this is a wildcard CRS, that is, one that will transform from and to any other CRS using the identity transformation
