For example <code><CODE>CRSFactory</CODE>.class</code> is a category, and <code><CODE>MathTransformFactory</CODE>.class</code> is an other category. <p> For each category, implementations are registered in a file placed in the directory, as specified in the <A HREF="http://java.sun.com/j2se/1.4/docs/api/javax/imageio/spi/ServiceRegistry.html" title="class or interface in javax.imageio.spi"><CODE>ServiceRegistry</CODE></A> javadoc. Those files are usually bundled into the JAR file distributed by the vendor. If the same file appears many time in different JARs, they are processed as if their content were merged. <p> Example use: <blockquote><pre> Set categories = Collections.singleton(new Class[] {MathTransformProvider.class}); FactoryRegistry registry = new FactoryRegistry(categories); // get the providers Iterator providers = registry.getProviders(MathTransformProvider.class) </pre></blockquote> <p> <strong>NOTE: This class is not thread safe</strong>. Users are responsable for synchronisation. This is usually done in an utility class wrapping this service registry (e.g. <A HREF="../../../org/geotools/referencing/FactoryFinder.html" title="class in org.geotools.referencing"><CODE>FactoryFinder</CODE></A>).<P><P><DL><DT><B>Since:</B></DT> <DD>2.1</DD><DT><B>Author:</B></DT> <DD>Martin Desruisseaux, Richard Gould, Jody Garnett</DD><DT><B>See Also:</B><DD><A HREF="../../../org/geotools/referencing/FactoryFinder.html" title="class in org.geotools.referencing"><CODE>FactoryFinder</CODE></A>, <A HREF="../../../org/geotools/coverage/FactoryFinder.html" title="class in org.geotools.coverage"><CODE>FactoryFinder</CODE></A><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/factory/FactoryRegistry.java">SVN head</A>)</DD></DL><HR><P><!-- ======== NESTED CLASS SUMMARY ======== --><A NAME="nested_class_summary"><!-- --></A><TABLE BORDER="1" WIDTH="100%" CELLPADDING="3" CELLSPACING="0" SUMMARY=""><TR BGCOLOR="#CCCCFF" CLASS="TableHeadingColor"><TD COLSPAN=2><FONT SIZE="+2"><B>Nested Class Summary</B></FONT></TD></TR></TABLE> <A NAME="nested_classes_inherited_from_class_javax.imageio.spi.ServiceRegistry"><!-- --></A><TABLE BORDER="1" WIDTH="100%" CELLPADDING="3" CELLSPACING="0" SUMMARY=""><TR BGCOLOR="#EEEEFF" CLASS="TableSubHeadingColor"><TD><B>Nested classes inherited from class <A HREF="http://java.sun.com/j2se/1.4/docs/api/javax/imageio/spi/ServiceRegistry.html" title="class or interface in javax.imageio.spi">ServiceRegistry</A></B></TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD><CODE><A HREF="http://java.sun.com/j2se/1.4/docs/api/javax/imageio/spi/ServiceRegistry.Filter.html" title="class or interface in javax.imageio.spi">ServiceRegistry.Filter</A></CODE></TD></TR></TABLE> <!-- =========== 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 static <A HREF="http://java.sun.com/j2se/1.4/docs/api/java/util/logging/Logger.html" title="class or interface in java.util.logging">Logger</A></CODE></FONT></TD><TD><CODE><B><A HREF="../../../org/geotools/factory/FactoryRegistry.html#LOGGER">LOGGER</A></B></CODE><BR> The logger for all events related to factory registry.</TD></TR></TABLE> <!-- ======== CONSTRUCTOR SUMMARY ======== --><A NAME="constructor_summary"><!-- --></A><TABLE BORDER="1" WIDTH="100%" CELLPADDING="3" CELLSPACING="0" SUMMARY=""><TR BGCOLOR="#CCCCFF" CLASS="TableHeadingColor"><TD COLSPAN=2><FONT SIZE="+2"><B>Constructor Summary</B></FONT></TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD><CODE><B><A HREF="../../../org/geotools/factory/FactoryRegistry.html#FactoryRegistry(java.util.Collection)">FactoryRegistry</A></B>(<A HREF="http://java.sun.com/j2se/1.4/docs/api/java/util/Collection.html" title="class or interface in java.util">Collection</A> categories)</CODE><BR> Constructs a new registry for the specified categories.</TD></TR></TABLE> <!-- ========== METHOD SUMMARY =========== -->⌨️ 快捷键说明
