Properties

	Name	Description of the
	CanRunDll	Dll with the instance of ICanRun. If available, CanRun is started before every of a node is called. If CanRun returns false, the start is cancelled. In CanRun, the parameters transferred via ref can also be be modified. (Inherited from NodeShellBase)
	CanRunDllPath	Path to an optional dll that provides an ICanRun instance. If available, before each run of the associated checker or worker CanRun is called. If CanRun returns false, the start is cancelled. The parameters transferred can also be modified in CanRun. (Inherited from NodeShellBase)
	CheckerLogger	An optional logger that is called by the node or zero. Is provided by the IJobProvider during instantiation.
	CheckerTrigger	An optional trigger that calls the job repeatedly or null (internally sets BreakWithResult to false). Is provided by the IJobProvider during instantiation.
	InitNodes	If True, all nodes in the tree are reset when this node is started. Can be used for loops in controlled jobs. Default: false.
	IsGlobal	If true, this node is created as a reference node if anywhere in the tree (not only in the current job) the name of the node has already been found. If false, the system only searches for nodes with the same name in the current job. Default: false.
	IsInvalid	With True, after successful global locking no further start attempt is made and the locking cancelled.
	LastReturned	The last result returned.
	ReferencedNodeName	Name of an originally referenced node or null.
	ReturnObject	Return object of the checker, can be null.
	TriggeredRunDelay	Delays the start of a node (and InitNodes). Can be used for loops in controlled jobs. Default: 0 (milliseconds).
	UserControlPath	The path to the UserControl currently to be loaded dynamically.

Methods

	Name	Description of the
	CanRun	Is used by Vishnu before each run of a Checker, Worker or before Start a trigger is called up. Returns true if the run/start can be executed. (Inherited from NodeShellBase)
	GetCheckerReference	Returns the name of the checker that is to be assigned to a ValueConverter.
	ModifyValue	Converts a value into a given format. Must be overwritten.
	Run	This is where the (normally external) work process is carried out (or observed).
	SetChecker	Takes over the checker for ValueConverters.
	SubNodeProgressChanged	Is activated if the processing progress of the checker has changed.

Events

	Name	Description of the
	NodeProgressChanged	Is called up if the processing progress of the checker has changed.
