GetTangentLock Method
Returns the state of a tangent join between this and another curve element at the given end-point.

Namespace: Autodesk.Revit.DB
Assembly: RevitAPI (in RevitAPI.dll) Version: 19.0.0.0 (19.0.0.405)
Since:  2017

Syntax

C#
public bool GetTangentLock(
	int end,
	ElementId other
)
Visual Basic
Public Function GetTangentLock ( _
	end As Integer, _
	other As ElementId _
) As Boolean
Visual C++
public:
bool GetTangentLock(
	int end, 
	ElementId^ other
)

Parameters

end
Type: System..::..Int32
Index of one of the curve's end. Values '0' and '1' indicate the start or end point, respectively.
other
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.

Remarks

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.

Exceptions

ExceptionCondition
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
