public abstract class AbstractFunctionTag

extends NodeReferrerTag

The function tags can be used as a child of a 'NodeProvider' tag (but not on clusternodes?), but it can also be used stand alone, when using the attributes to specify on which object the function must be called (besides nodes, it can be called on node-manager, modules, sets). This is the absctract implementation, providing only the result of the function. The several extensions cast to the right type, and handle it on a specific way.
