By using the Pull Service you can avoid having to make Screens to populate a context for use in a particular template. The Pull Service creates a set of tools, as specified in the TR.props file. These tools can have global scope, request scope, session scope (i.e. stored in user temp hashmap) or persistent scope (i.e. stored in user perm hashmap) The standard way of referencing these global tools is through the toolbox handle. This handle is typically $toolbox, but can be specified in the TR.props file. So, for example, if you had a UI Manager tool which created a set of UI attributes from a properties file, and one of the properties was 'bgcolor', then you could access this UI attribute with $ui.bgcolor. The identifier that is given to the tool, in this case 'ui', can be specified as well.<P><DL><DT><B>Version: </B><DD>$Id: PullService.java,v 1.1.1.1 2001/08/16 05:09:10 jvanzyl Exp $</DD><DT><B>Author: </B><DD><a href="mailto:jvanzyl@periapt.com">Jason van Zyl</a></DD></DL><HR><P><!-- ======== INNER CLASS SUMMARY ======== --><!-- =========== FIELD SUMMARY =========== --><A NAME="field_summary"><!-- --></A><TABLE BORDER="1" CELLPADDING="3" CELLSPACING="0" WIDTH="100%"><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>static java.lang.String</CODE></FONT></TD><TD><CODE><B><A HREF="../../../../../org/apache/turbine/services/pull/PullService.html#SERVICE_NAME">SERVICE_NAME</A></B></CODE><BR> The key under which this service is stored in TurbineServices.</TD></TR></TABLE> <!-- ======== CONSTRUCTOR SUMMARY ======== --><!-- ========== METHOD SUMMARY =========== --><A NAME="method_summary"><!-- --></A><TABLE BORDER="1" CELLPADDING="3" CELLSPACING="0" WIDTH="100%"><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> java.lang.String</CODE></FONT></TD><TD><CODE><B><A HREF="../../../../../org/apache/turbine/services/pull/PullService.html#getAbsolutePathToResourcesDirectory()">getAbsolutePathToResourcesDirectory</A></B>()</CODE><BR> Return the absolute path of the resources directory used by application tools.</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE> org.apache.velocity.context.Context</CODE></FONT></TD><TD><CODE><B><A HREF="../../../../../org/apache/turbine/services/pull/PullService.html#getGlobalContext()">getGlobalContext</A></B>()</CODE><BR> Get the context containing global tools that will be use as part of the Turbine Pull Model.</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE> java.lang.String</CODE></FONT></TD><TD><CODE><B><A HREF="../../../../../org/apache/turbine/services/pull/PullService.html#getResourcesDirectory()">getResourcesDirectory</A></B>()</CODE><BR> Return the resources directory.</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE> void</CODE></FONT></TD><TD><CODE><B><A HREF="../../../../../org/apache/turbine/services/pull/PullService.html#populateContext(org.apache.velocity.context.Context, org.apache.turbine.util.RunData)">populateContext</A></B>(org.apache.velocity.context.Context context, <A HREF="../../../../../org/apache/turbine/util/RunData.html">RunData</A> data)</CODE><BR> Populate the given context with all request, session and persistent scope tools (it is assumed that the context already wraps the global context, and thus already contains the global tools).</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE> void</CODE></FONT></TD><TD><CODE><B><A HREF="../../../../../org/apache/turbine/services/pull/PullService.html#refreshGlobalTools()">refreshGlobalTools</A></B>()</CODE><BR> Refresh the global tools .</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="../../../../../org/apache/turbine/services/pull/PullService.html#refreshToolsPerRequest()">refreshToolsPerRequest</A></B>()</CODE><BR> Shoud we refresh the tools on each request.</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE> void</CODE></FONT></TD><TD><CODE><B><A HREF="../../../../../org/apache/turbine/services/pull/PullService.html#releaseTools(org.apache.velocity.context.Context)">releaseTools</A></B>(org.apache.velocity.context.Context context)</CODE>⌨️ 快捷键说明
