The OGC srid corresponds more closely to the DB2 'csid' value. This makes life quite confusing because the DB2 'srid' is needed to construct geometries in the database. GeoTools needs the 'csid' which generally corresponds to an EPSG coordinate system identifier in order to create an OGC coordinate system reference. </b> </p> <p> <b> We also assume that there is a single 'srid' associated with all the geometries in a particular geometry column. This is not required by DB2. </b> </p> <p> Do we need to consider freeing this up at some point as the HashMap of catalogs is stored in a class variable? </p><P><P><DL><DT><B>Author:</B></DT> <DD>David Adler - IBM Corporation</DD><DT><B>Module:</B></DT><DD><CODE><B>plugin/db2</B></CODE> (<A HREF="http://maven.geotools.fr/repository/org/geotools/gt2-db2/"><CODE>gt2-db2.jar</CODE></A>) (<A HREF="http://maven.geotools.fr/reports/db2/index.html">Maven report</A>) (<A HREF="http://svn.geotools.org/geotools/tags/2.3.2/plugin/db2/src/org/geotools/data/db2/DB2SpatialCatalog.java">SVN head</A>)</DD></DL><HR><P><!-- ======== NESTED CLASS SUMMARY ======== --><!-- =========== FIELD SUMMARY =========== --><!-- ======== CONSTRUCTOR SUMMARY ======== --><!-- ========== METHOD SUMMARY =========== --><A NAME="method_summary"><!-- --></A><TABLE BORDER="1" WIDTH="100%" CELLPADDING="3" CELLSPACING="0" SUMMARY=""><TR BGCOLOR="#CCCCFF" CLASS="TableHeadingColor"><TD COLSPAN=2><FONT SIZE="+2"><B>Method Summary</B></FONT></TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE>static <A HREF="http://java.sun.com/j2se/1.4/docs/api/java/lang/String.html" title="class or interface in java.lang">String</A></CODE></FONT></TD><TD><CODE><B><A HREF="../../../../org/geotools/data/db2/DB2SpatialCatalog.html#geomID(java.lang.String, java.lang.String, java.lang.String)">geomID</A></B>(<A HREF="http://java.sun.com/j2se/1.4/docs/api/java/lang/String.html" title="class or interface in java.lang">String</A> tableSchema, <A HREF="http://java.sun.com/j2se/1.4/docs/api/java/lang/String.html" title="class or interface in java.lang">String</A> tableName, <A HREF="http://java.sun.com/j2se/1.4/docs/api/java/lang/String.html" title="class or interface in java.lang">String</A> columnName)</CODE><BR> A convenience method to nicely format the schema, table and column name.</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE>static <A HREF="../../../../org/geotools/data/db2/DB2SpatialCatalog.html" title="class in org.geotools.data.db2">DB2SpatialCatalog</A></CODE></FONT></TD><TD><CODE><B><A HREF="../../../../org/geotools/data/db2/DB2SpatialCatalog.html#getInstance(java.lang.String, java.lang.String, java.sql.Connection)">getInstance</A></B>(<A HREF="http://java.sun.com/j2se/1.4/docs/api/java/lang/String.html" title="class or interface in java.lang">String</A> dbURL, <A HREF="http://java.sun.com/j2se/1.4/docs/api/java/lang/String.html" title="class or interface in java.lang">String</A> tableSchema, <A HREF="http://java.sun.com/j2se/1.4/docs/api/java/sql/Connection.html" title="class or interface in java.sql">Connection</A> conn)</CODE>⌨️ 快捷键说明
