Syntax

C#
public abstract ILinearNumExpr GetCandidateRay()

Return Value

An expression representing the ray. Every non-zero coefficient in the ray has the respective non-zero coefficient in the return expression.

Remarks

This method returns the unbounded ray as a sparse expression.

This method can be invoked only from Cplex.Callback.Context.Id.Candidate and if Cplex.Callback.Context.IsCandidateRay() returns true; it throws an exception when invoked from another context.

Throws ILOG.Concert.Exception if any error occurs during the query.
