public abstract class AbstractNodeProviderTag

extends CloudReferrerTag

implements NodeProvider

A base class for tags which provide a node (And some fields). The general attributes for a NodeProvider are

• id: The identifier. Used as a key for the Context. If this attribute is missing, the Node variable will not be imported in the Context.
• jspvar: An identifier for a jsp variable available in the body. If this attribute is missing, no jsp-variable will be created.
