HierarchySensor

This node monitors the subtree which is defined by the children of the parent nodes. A single hierarchy_changed(TRUE) event is send once per frame if the topology of the child-subtree has changed (= node added/removed)

id Name DataType PartType Default ValueType Description
SFTime hierarchy_changed SFTime outputOnly outslot which send a TRUE if the hierachy defined by the parent node has be changed
SFString triggerName SFString initializeOnly Synchronize name of the dynamic context-slot which is used by the run-time environment (e.g. Jobs) to trigger the node. Life-Nodes will automatically connect the context-eventOutut to the triggerSlot-eventInput Slot.
SFString description SFString inputOutput Text description to comment the sensor task. Can be used in run-time systems to give usefull feedback to the user and developer
SFBool enabled SFBool inputOutput TRUE Enables/disables the sensor node.
SFBool isActive SFBool outputOnly FALSE isActive true/false events are sent when the sensor gets active
SFTime triggerSlot SFTime inputOnly slot which is used internally to connect a dynamic context-slot which name is set by the triggerName value. Its used automatically to install run-time environment trigger.
MFString logFeature MFString inputOutput state, child, parent, route, eventIn, eventOut controls the logging of changes, state: log state changes (e.g. live), child: log child add/remove, parent: log parent add/remove, route: log route add/remove; eventIn: log receiving of events, eventOut: log sending of events: guiView, runtime system should create node-view, guiEdit: runtime system should create node-editeverything: log everything
SFNode metadata SFNode inputOutput MetadataObject container for payload metadata inside MetadataSet element
