17.12 Node Triggers

Triggers attached to nodes follow the same basic rules and formats as attaching them to other objects; however, not all attribute options are valid for each object. Nodes, like the other objects, have a unique set of trigger rules. The table below details the methods, options, and other notable details that come with attaching triggers to nodes.
