[OmniFaces utilities 2.0] Check if the given collection contains an object with the given class name


[OmniFaces utilities] The containsByClassName() method checks if the given collection contains an object with the given class name.

Method:
Usage:

UIForm form = Components.getCurrentForm();
List<UIComponent> children = form.getChildren();

Check if at least one of the current form children is a password field:

import org.omnifaces.util.Utils;
...          
boolean isAtLeastOnePasswordFieldInForm = Utils.containsByClassName(children, "javax.faces.component.html.HtmlInputSecret");

Check if the current form was submitted via an UICommand of type HtmlCommandButton or HtmlCommandLink:

import org.omnifaces.util.Utils;
