This factory is mostly used by application expecting geographic coordinates in (<var>longitude</var>, <var>latitude</var>) order, while most geographic CRS specified in the <A HREF="http://www.epsg.org">EPSG database</A> use the opposite axis order. <p> It is better to avoid this class if you can. This class exists primarily for compatibility with external data or applications that assume (<var>longitude</var>, <var>latitude</var>) axis order no matter what the EPSG database said, for example Shapefiles. <p> The axis order can be specified at construction time as an array of axis directions. If no such array is explicitly specified, then the default order is East, East-North-East, North-East, North-North-East, North, Up, Geocentric X, Geocentric Y, Geocentric Z, Column, Row, Display right, Display up and Future. This means that, for example, axis with East or West direction will be placed before any axis with North or South direction. Axis directions not specified in the table (for example <CODE>OTHER</CODE>) will be ordered last. This is somewhat equivalent to the ordering of <A HREF="http://java.sun.com/j2se/1.4/docs/api/java/lang/Double.html#NaN" title="class or interface in java.lang"><CODE>NaN</CODE></A> values in an array of . <p> <strong>Notes:</strong> <ul> <li>This class compares only the "absolute" axis directions, so North and South are considered equivalent.</li> <li>The default direction order may changes in future Geotools version in order to fit what appears to be the most common usage on the market.</li> <li>The actual axis ordering is determined by the <A HREF="../../../../org/geotools/referencing/factory/OrderedAxisAuthorityFactory.html#compare(java.lang.Object, java.lang.Object)"><CODE>compare</CODE></A> method implementation. Subclasses may override this method if the want to provide a more sophesticated axis ordering.</li> </ul> <p> For some authority factories, an instance of this class can be obtained by passing a <A HREF="../../../../org/geotools/factory/Hints.html#FORCE_LONGITUDE_FIRST_AXIS_ORDER"><CODE>FORCE_LONGITUDE_FIRST_AXIS_ORDER</CODE></A> hint to the <code><A HREF="../../../../org/geotools/referencing/FactoryFinder.html#getCRSAuthorityFactory(java.lang.String, org.geotools.factory.Hints)">FactoryFinder.getCRSAuthorityFactory</A>(...)</code> method. Whatever this hint is supported or not is authority dependent. Example: <blockquote><pre> Hints hints = new Hints(Hints.FORCE_LONGITUDE_FIRST_AXIS_ORDER, Boolean.TRUE); CRSAuthorityFactory factory = FactoryFinder.getCRSAuthorityFactory("EPSG", hints); CoordinateReferenceSystem crs = factory.createCoordinateReferenceSystem("EPSG:4326"); </pre></blockquote> This class is named <cite>ordered axis authority factory</cite> instead of something like <cite>longitude first axis order</cite> because the axis order can be user-supplied. The (<var>longitude</var>, <var>latitude</var>) order just appears to be the default one.<P><P><DL><DT><B>Since:</B></DT> <DD>2.2</DD><DT><B>Author:</B></DT> <DD>Martin Desruisseaux</DD><DT><B>See Also:</B><DD><A HREF="../../../../org/geotools/factory/Hints.html#FORCE_LONGITUDE_FIRST_AXIS_ORDER"><CODE>Hints.FORCE_LONGITUDE_FIRST_AXIS_ORDER</CODE></A>, <A HREF="../../../../org/geotools/factory/Hints.html#FORCE_STANDARD_AXIS_UNITS"><CODE>Hints.FORCE_STANDARD_AXIS_UNITS</CODE></A><DT><B>Tutorial:</B></DT><DD><A HREF="http://docs.codehaus.org/display/GEOTOOLS/The+axis+order+issue">The axis order issue</A></DD><DT><B>Module:</B></DT><DD><CODE><B>module/referencing</B></CODE> (<A HREF="http://maven.geotools.fr/repository/org/geotools/gt2-referencing/"><CODE>gt2-referencing.jar</CODE></A>) (<A HREF="http://maven.geotools.fr/reports/referencing/index.html">Maven report</A>) (<A HREF="http://svn.geotools.org/geotools/tags/2.3.2/module/referencing/src/org/geotools/referencing/factory/OrderedAxisAuthorityFactory.java">SVN head</A>)</DD></DL><HR><P><!-- ======== NESTED CLASS SUMMARY ======== --><!-- =========== FIELD SUMMARY =========== --><A NAME="field_summary"><!-- --></A><TABLE BORDER="1" WIDTH="100%" CELLPADDING="3" CELLSPACING="0" SUMMARY=""><TR BGCOLOR="#CCCCFF" CLASS="TableHeadingColor"><TD COLSPAN=2><FONT SIZE="+2"><B>Field Summary</B></FONT></TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE>protected boolean</CODE></FONT></TD><TD><CODE><B><A HREF="../../../../org/geotools/referencing/factory/OrderedAxisAuthorityFactory.html#forceStandardDirections">forceStandardDirections</A></B></CODE><BR> if this authority factory should also force the axis to their standard direction. </TD></TR><TR BGCOLOR="white" CLASS="TableRowColor">⌨️ 快捷键说明
