Syntax
public IList<RebarConstraint> GetConstraintCandidatesForHandle( RebarConstrainedHandle handle, Reference reference )
Public Function GetConstraintCandidatesForHandle ( handle As RebarConstrainedHandle, reference As Reference ) As IList(Of RebarConstraint)
public: IList<RebarConstraint^>^ GetConstraintCandidatesForHandle( RebarConstrainedHandle^ handle, Reference^ reference )
member GetConstraintCandidatesForHandle : handle : RebarConstrainedHandle * reference : Reference -> IList<RebarConstraint>
Parameters
- handle RebarConstrainedHandle
- The RebarConstrainedHandle for which constraint candidates are sought.
- reference Reference
- The reference you want to constrain to. It can be a reference to any host in the model or any bar from any host.
Return Value
IListRebarConstraintA collection of RebarConstraints

Exception | Condition |
---|---|
ArgumentException | reference is not from a valid RebarConstraint target element. |
ArgumentNullException | A non-optional argument was null |
