Using Liferay Util Buffer

The buffer tag is not a self-closing tag. The content placed between the opening and closing of this tag is saved to a buffer and its output is assigned to the Java variable declared with the tag’s var attribute. The output is returned as a String, letting you post-process it. For example, you can use this to override a JSP’s existing contents.

The example below saves the link’s generated markup to a buffer and then uses the returned string as the argument for a liferay-ui:message key:

<liferay-util:buffer
		var="linkContent"
>
		<aui:a 
			href="https://portal.liferay.dev/" 
			target="_blank">the Liferay Portal project
		</aui:a>
</liferay-util:buffer>

<liferay-ui:message 
		arguments="<%= linkContent %>" 
		key="see-x-for-more-information" 
		translateArguments="<%= false %>" 
/>

Now you know how to use the <liferay-util:buffer> tag to save content to a buffer.
