[OmniFaces utilities 2.0] Write component attribute of the given name as given HTML attribute name

[OmniFaces utilities] The writeAttribute() method writes component attribute of the given name, if it's not empty, as given HTML attribute name. Component property name defaults to the given component attribute name.


Use the below Renderers#writeAttribute() whenever you need to render the attribute of a component (if it's not empty) for which you can provide:

·         the ResponseWriter instance
·         the associated UI component (usually the parent component)
·         the component attribute name whose value should be written
·         the HTML attribute name to be written
·         component property name defaults to the given component attribute name

Below you can see two examples:

import org.omnifaces.util.Renderers;
public void encodeBegin(FacesContext context) throws IOException {
 ResponseWriter writer = context.getResponseWriter();
 Renderers.writeAttribute(writer, this, "value", "src");
 Renderers.writeAttribute(writer, getParent(), "styleClass", "class");
