All methods first looks if a previously created object exists for the given code. If such an object exists, it is returned. Otherwise, the object creation is delegated to the <A HREF="../../../../org/geotools/referencing/factory/AbstractAuthorityFactory.html" title="class in org.geotools.referencing.factory">authority factory</A> specified at creation time, and the result is cached in this buffered factory. <p> Objects are cached by strong references, up to the amount of objects specified at construction time. If a greater amount of objects are cached, the oldest ones will be retained through a <A HREF="http://java.sun.com/j2se/1.4/docs/api/java/lang/ref/WeakReference.html" title="class or interface in java.lang.ref">weak reference</A> instead of a strong one. This means that this buffered factory will continue to returns them as long as they are in use somewhere else in the Java virtual machine, but will be discarted (and recreated on the fly if needed) otherwise.<P><P><DL><DT><B>Since:</B></DT> <DD>2.1</DD><DT><B>Author:</B></DT> <DD>Martin Desruisseaux</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/BufferedAuthorityFactory.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></TABLE> <A NAME="fields_inherited_from_class_ReferencingFactory"><!-- --></A><TABLE BORDER="1" WIDTH="100%" CELLPADDING="3" CELLSPACING="0" SUMMARY=""><TR BGCOLOR="#EEEEFF" CLASS="TableSubHeadingColor"><TD><B>Fields inherited from class <A HREF="../../../../org/geotools/referencing/factory/ReferencingFactory.html" title="class in org.geotools.referencing.factory">ReferencingFactory</A></B></TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD><CODE><A HREF="../../../../org/geotools/referencing/factory/ReferencingFactory.html#LOGGER">LOGGER</A></CODE></TD></TR></TABLE> <A NAME="fields_inherited_from_class_AbstractFactory"><!-- --></A><TABLE BORDER="1" WIDTH="100%" CELLPADDING="3" CELLSPACING="0" SUMMARY=""><TR BGCOLOR="#EEEEFF" CLASS="TableSubHeadingColor"><TD><B>Fields inherited from class <A HREF="../../../../org/geotools/factory/AbstractFactory.html" title="class in org.geotools.factory">AbstractFactory</A></B></TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD><CODE><A HREF="../../../../org/geotools/factory/AbstractFactory.html#hints">hints</A>, <A HREF="../../../../org/geotools/factory/AbstractFactory.html#MAXIMUM_PRIORITY">MAXIMUM_PRIORITY</A>, <A HREF="../../../../org/geotools/factory/AbstractFactory.html#MINIMUM_PRIORITY">MINIMUM_PRIORITY</A>, <A HREF="../../../../org/geotools/factory/AbstractFactory.html#NORMAL_PRIORITY">NORMAL_PRIORITY</A>, <A HREF="../../../../org/geotools/factory/AbstractFactory.html#priority">priority</A></CODE></TD></TR></TABLE> ⌨️ 快捷键说明
