Class SimpleCRS

Object

SimpleIdentifiedObject

SimpleCRS

All Implemented Interfaces:

Identifier, CoordinateReferenceSystem, SingleCRS, CoordinateSystem, IdentifiedObject, ReferenceIdentifier, ReferenceSystem

Direct Known Subclasses:

SimpleCRS.Geographic, SimpleCRS.Temporal, SimpleCRS.Vertical

public abstract class SimpleCRS
extends SimpleIdentifiedObject
implements SingleCRS, CoordinateSystem

A CoordinateReferenceSystem abstract base class. This class does not make distinction between Coordinate System and Coordinate Reference System, so we implement the two interfaces by the same class.

Since:

3.1

axes

protected final CoordinateSystemAxis[] axes

The coordinate system axes. The length of this array is the coordinate system dimension.

• getDimension()
• getAxis(int)

Constructor Details

SimpleCRS

public SimpleCRS(Citation authority,
 String name,
 CoordinateSystemAxis... axes)

Creates a new CRS for the given name, datum and axes.

Parameters:

authority - organization responsible for definition of the CRS, or null.

name - the name of the new CRS.

axes - the axes to be returned by getAxis(int). The length of this array is the coordinate system dimension.

Method Details

getCoordinateSystem

public CoordinateSystem getCoordinateSystem()

Returns the coordinate system, which is represented directly by this implementation class since it does not distinguish CS and CRS.

Specified by:

getCoordinateSystem in interface CoordinateReferenceSystem

Specified by:

getCoordinateSystem in interface SingleCRS

Returns:

the coordinate system.

getDimension

public final int getDimension()

Returns the dimension of the coordinate system.

Specified by:

getDimension in interface CoordinateSystem

Returns:

the dimension of the coordinate system.

getAxis

public final CoordinateSystemAxis getAxis(int dimension)
                                   throws IndexOutOfBoundsException

Returns the coordinate axis at the given dimension.

Specified by:

getAxis in interface CoordinateSystem

Parameters:

dimension - the zero based index of axis.

Returns:

the axis at the specified dimension.

Throws:

IndexOutOfBoundsException - if dimension is out of bounds.

equals

public boolean equals(Object object)

Compares this CRS with the given object for equality.

Overrides:

equals in class SimpleIdentifiedObject

Parameters:

object - the object to compare with this SimpleCRS.

Returns:

true if the given object is equal to this object.
