| <h1 class="content-header header-section1" id="pgui_quickstart_merge" itemprop="headline">Merging the template with the data-model</h1> |
| </div></div><p>As we know, data-model + template = output, and we have a |
| data-model (<code class="inline-code">root</code>) and a template |
| (<code class="inline-code">temp</code>), so to get the output we have to merge them. |
| This is done by the <code class="inline-code">process</code> method of the template. |
| It takes the data-model root and a <code class="inline-code">Writer</code> as |
| parameters. It writes the produced output to the |
| <code class="inline-code">Writer</code>. For the sake of simplicity here I write to |
| the standard output:</p> |
| |
| <div class="code-wrapper"><pre class="code-block code-unspecified">Writer out = new OutputStreamWriter(System.out); |
| temp.process(root, out); |
| out.flush();</pre></div><p>This will print to your terminal the output what you have seen |
| in the <a href="dgui_quickstart_basics.html#example.first">first example</a> of the |
| Template Author's Guide.</p><p>Once you have obtained a <code class="inline-code">Template</code> instance, |
| you can merge it with different data-models for unlimited times |
| (<code class="inline-code">Template</code> instances are basically stateless). Also, |
| the <code class="inline-code">test.ftl</code> file is accessed only while the |
| <code class="inline-code">Template</code> instance is created, not when you call the |
| process method.</p><div class="bottom-pagers-wrapper"><div class="pagers bottom"><a class="paging-arrow previous" href="pgui_quickstart_gettemplate.html"><span>Previous</span></a><a class="paging-arrow next" href="pgui_quickstart_all.html"><span>Next</span></a></div></div></div></div> </div> |
