	other As ElementId _
) As Boolean

bool GetTangentLock(
	int end, 
	ElementId^ other


Type: System Int32
Index of one of the curve's end. Values '0' and '1' indicate the start or end point, respectively.
Type: Autodesk.Revit.DB ElementId
ElementId of another Curve Element from the same document.

Return Value

Returns True if this curve element has a tangent joint with the other input element and the join is curently locked; returns False otherwise.


The return value indicates whether there is such tangent join and if it is currently locked. A negative value indicates that there either is no tangent join with the other element at the given end-point, or the join between those two curve element is not currently locked.


Exception Condition
Autodesk.Revit.Exceptions ArgumentException The given Id does not represent any of the two end-points of a curve element. A valid value of either '0' or '1' is expected. -or- The given ElementId (%elementId) is not of a valid Curve Element. A valid Curve Element must be in the same document and must be diferent than this curve elements self. -or- This element has no tangent join with the input element at the given end-point.
Autodesk.Revit.Exceptions ArgumentNullException A non-optional argument was NULL
