Class SubTypes

java.lang.Object

org.apache.sis.referencing.crs.SubTypes

All Implemented Interfaces:

Comparator<Object>

final class SubTypes
extends Object
implements Comparator<Object>

Implementation of AbstractCRS methods that require knowledge about subclasses. Those methods are defined in a separated static class for avoiding class loading of all coordinate reference system implementations before necessary.

This class currently provides implementation for the following methods:

• AbstractCRS.castOrCopy(CoordinateReferenceSystem)
• DefaultCompoundCRS.forConvention(AxesConvention)

Since:

0.4

Version:

0.7

Field Summary

Fields

Modifier and Type	Field	Description
(package private) static final Comparator<Object>	BY_TYPE	A comparator for sorting CRS objects by their types.
private static final Class<?>[]	TYPE_ORDER	CRS types to sort first in a compound CRS.

Method Summary

Modifier and Type	Method	Description
(package private) static AbstractCRS	castOrCopy(org.opengis.referencing.crs.CoordinateReferenceSystem object)	Returns a SIS implementation for the given coordinate reference system.

Field Details

TYPE_ORDER

private static final Class<?>[] TYPE_ORDER

CRS types to sort first in a compound CRS. Any type not in this list will be sorted last. Used for implementation of BY_TYPE comparator.

BY_TYPE

static final Comparator<Object> BY_TYPE

A comparator for sorting CRS objects by their types. The comparison sorts projected CRS first, followed by geodetic, vertical then temporal CRS.

Constructor Details

SubTypes

private SubTypes()

Do not allow instantiation of this class (except the singleton).

Method Details

indexOf

private static int indexOf(Object object)

Returns the index of the interface implemented by the given object.

compare

public int compare(Object o1,
 Object o2)

Implementation of BY_TYPE comparator.

Specified by:

compare in interface Comparator<Object>

castOrCopy

static AbstractCRS castOrCopy(org.opengis.referencing.crs.CoordinateReferenceSystem object)

Returns a SIS implementation for the given coordinate reference system.
