The above means that there are two acceptable values for the Object []
passed into <a href="provider/IContainerInstantiator.html#createInstance(org.eclipse.ecf.core.ContainerTypeDescription,java.lang.Object%5B%5D)"><code>IContainerInstantiator.createInstance(ContainerTypeDescription, Object[])</code></a>:
1) a single String, and 2) two Strings. These would therefore be
acceptable as input to createInstance:
<pre>
IContainer container = ContainerFactory.getDefault().createContainer(
description, new Object[] { &quot;Hello&quot; });
IContainer container2 = ContainerFactory.getDefault().createContainer(
description, new Object[] { &quot;Hello&quot; });
</pre>
