<div class="block">Creates an instance of the resource object.
<p>The resource interface has methods that return <a href="Resources.Inst.html" title="class in org.apache.calcite.runtime"><code>Resources.Inst</code></a> and
<a href="Resources.ExInst.html" title="class in org.apache.calcite.runtime"><code>Resources.ExInst</code></a> values. Each of those methods is basically a factory method.
<p>This method creates an instance of that interface backed by a resource
bundle, using a dynamic proxy (<code>Proxy</code>).
<p>Suppose that base = "com.example.MyResource" and the current locale is
"en_US". A method
<blockquote>
&#64;BaseMessage("Illegal binary string {0}")
ExInst&lt;IllegalArgumentException&gt; illegalBinaryString(String a0);
</blockquote>
will look up a resource "IllegalBinaryString" from the resource file
"com/example/MyResource_en_US.properties", and substitute in the parameter
value <code>a0</code>.
<p>The resource in the properties file may or may not be equal to the
base message "Illegal binary string {0}". But in the base locale, it
probably should be.</div>
