A change listener can be specified in the connection string. It is used to ask what is changed in the datasource (e.g. database). Everytime mondrian has to decide whether it will use data from cache, it will call the change listener. When the change listener tells mondrian the datasource has changed for a dimension, cube, ... then mondrian will flush the cache and read from database again. It is specified in the connection string, like this: <blockquote><code> Jdbc=jdbc:odbc:MondrianFoodMart; JdbcUser=ziggy; JdbcPassword=stardust; DataSourceChangeListener=com.acme.MyChangeListener; </code></blockquote> This class should be called in mondrian before any data is read, so even before cache is build. This way, the plugin is able to register the first timestamp mondrian tries to read the datasource.<P><P><DL><DT><B>Since:</B></DT> <DD>Dec 12, 2006</DD><DT><B>Version:</B></DT> <DD>$Id: //open/mondrian-release/3.0/src/main/mondrian/spi/impl/DataSourceChangeListenerImpl4.java#2 $</DD><DT><B>Author:</B></DT> <DD>Bart Pappyn</DD></DL><HR><P><!-- =========== FIELD SUMMARY =========== --><A NAME="field_summary"><!-- --></A><TABLE BORDER="1" WIDTH="100%" CELLPADDING="3" CELLSPACING="0" SUMMARY=""><TR BGCOLOR="#CCCCFF" CLASS="TableHeadingColor"><TH ALIGN="left" COLSPAN="2"><FONT SIZE="+2"><B>Field Summary</B></FONT></TH></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE>(package private) <A HREF="http://java.sun.com/javase/6/docs/api/java/util/Random.html" title="class or interface in java.util">Random</A></CODE></FONT></TD><TD><CODE><B><A HREF="../../../mondrian/spi/impl/DataSourceChangeListenerImpl4.html#random">random</A></B></CODE><BR> </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"><TH ALIGN="left" COLSPAN="2"><FONT SIZE="+2"><B>Constructor Summary</B></FONT></TH></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD><CODE><B><A HREF="../../../mondrian/spi/impl/DataSourceChangeListenerImpl4.html#DataSourceChangeListenerImpl4()">DataSourceChangeListenerImpl4</A></B>()</CODE><BR> Creates a new instance of DataSourceChangeListenerImpl2</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD><CODE><B><A HREF="../../../mondrian/spi/impl/DataSourceChangeListenerImpl4.html#DataSourceChangeListenerImpl4(int, int)">DataSourceChangeListenerImpl4</A></B>(int flushInverseFrequencyHierarchy, int flushInverseFrequencyAggregation)</CODE><BR> </TD></TR></TABLE> <!-- ========== METHOD SUMMARY =========== --><A NAME="method_summary"><!-- --></A><TABLE BORDER="1" WIDTH="100%" CELLPADDING="3" CELLSPACING="0" SUMMARY=""><TR BGCOLOR="#CCCCFF" CLASS="TableHeadingColor"><TH ALIGN="left" COLSPAN="2"><FONT SIZE="+2"><B>Method Summary</B></FONT></TH></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE> <A HREF="http://java.sun.com/javase/6/docs/api/java/lang/String.html" title="class or interface in java.lang">String</A></CODE></FONT></TD><TD><CODE><B><A HREF="../../../mondrian/spi/impl/DataSourceChangeListenerImpl4.html#getTableName(mondrian.rolap.RolapHierarchy)">getTableName</A></B>(<A HREF="../../../mondrian/rolap/RolapHierarchy.html" title="class in mondrian.rolap">RolapHierarchy</A> hierarchy)</CODE><BR> </TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE> boolean</CODE></FONT></TD><TD><CODE><B><A HREF="../../../mondrian/spi/impl/DataSourceChangeListenerImpl4.html#isAggregationChanged(mondrian.rolap.agg.Aggregation)">isAggregationChanged</A></B>(<A HREF="../../../mondrian/rolap/agg/Aggregation.html" title="class in mondrian.rolap.agg">Aggregation</A> aggregation)</CODE><BR> Checks if the given aggregation has changed since the previous time this function was called.</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor">⌨️ 快捷键说明
