Underlying it is the existing member reader. <h3>Synchronization</h3> <p>Most synchronization takes place within SmartMemberReader. All synchronization is done on the cacheHelper object.</p> <h3>Caching strategy</h3> <p>We take the following approach to caching RolapCubeMember objects: <p><b>RolapHierarchy.SmartMemberReader.SmartCacheHelper</b> is the shared cache across shared hierarchies. This member cache only contains members loaded by non-cube specific member lookups. This cache should only contain RolapMembers, not RolapCubeMembers. <p><b>RolapCubeHierarchy.RolapCubeHierarchyMemberReader.rolapCubeCacheHelper</b> is a cache that contains the RolapCubeMember objects, which are cube-specific wrappers of shared members.</p> <p><b>RolapCubeHierarchy.RolapCubeHierarchyMemberReader.SmartCacheHelper</b> is the inherited shared cache from SmartMemberReader, and is used when a join with the fact table is necessary, SqlContextConstraint.isJoinRequired(). This cache may be redundant with rolapCubeCacheHelper.</p> <p>A special note regarding RolapCubeHierarchyMemberReader.cubeSource. This class was required for the special situation getMemberBuilder() method call from RolapNativeSet. This class utilizes both the rolapCubeCacheHelper class for storing RolapCubeMembers, and also the RolapCubeHierarchyMemberReader's inherited SmartCacheHelper.</p> <p>The <A HREF="../../mondrian/olap/MondrianProperties.html#EnableRolapCubeMemberCache"><CODE>MondrianProperties.EnableRolapCubeMemberCache</CODE></A> property allows you to disable the RolapCubeMember cache.</p><P><P><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"><TH ALIGN="left" COLSPAN="2"><FONT SIZE="+2"><B>Nested Class Summary</B></FONT></TH></TR></TABLE> <A NAME="nested_classes_inherited_from_class_mondrian.rolap.SmartMemberReader"><!-- --></A><TABLE BORDER="1" WIDTH="100%" CELLPADDING="3" CELLSPACING="0" SUMMARY=""><TR BGCOLOR="#EEEEFF" CLASS="TableSubHeadingColor"><TH ALIGN="left"><B>Nested classes/interfaces inherited from class mondrian.rolap.<A HREF="../../mondrian/rolap/SmartMemberReader.html" title="class in mondrian.rolap">SmartMemberReader</A></B></TH></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD><CODE><A HREF="../../mondrian/rolap/SmartMemberReader.SiblingIterator.html" title="class in mondrian.rolap">SmartMemberReader.SiblingIterator</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"><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>protected <A HREF="../../mondrian/rolap/RolapCubeHierarchy.RolapCubeSqlMemberSource.html" title="class in mondrian.rolap">RolapCubeHierarchy.RolapCubeSqlMemberSource</A></CODE></FONT></TD><TD><CODE><B><A HREF="../../mondrian/rolap/RolapCubeHierarchy.RolapCubeHierarchyMemberReader.html#cubeSource">cubeSource</A></B></CODE><BR> cubeSource is passed as our member builder</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE>protected <A HREF="../../mondrian/rolap/MemberCacheHelper.html" title="class in mondrian.rolap">MemberCacheHelper</A></CODE></FONT></TD><TD><CODE><B><A HREF="../../mondrian/rolap/RolapCubeHierarchy.RolapCubeHierarchyMemberReader.html#rolapCubeCacheHelper">rolapCubeCacheHelper</A></B></CODE><BR> this cache caches RolapCubeMembers that are light wrappers around shared and non-shared Hierarchy RolapMembers.</TD></TR></TABLE> <A NAME="fields_inherited_from_class_mondrian.rolap.SmartMemberReader"><!-- --></A><TABLE BORDER="1" WIDTH="100%" CELLPADDING="3" CELLSPACING="0" SUMMARY=""><TR BGCOLOR="#EEEEFF" CLASS="TableSubHeadingColor"><TH ALIGN="left"><B>Fields inherited from class mondrian.rolap.<A HREF="../../mondrian/rolap/SmartMemberReader.html" title="class in mondrian.rolap">SmartMemberReader</A></B></TH></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD><CODE><A HREF="../../mondrian/rolap/SmartMemberReader.html#cacheHelper">cacheHelper</A>, <A HREF="../../mondrian/rolap/SmartMemberReader.html#rootMembers">rootMembers</A>, <A HREF="../../mondrian/rolap/SmartMemberReader.html#source">source</A></CODE></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">⌨️ 快捷键说明
