Reference documentation and code samples for the Cloud Optimization V1 API class Google::Cloud::Optimization::V1::ShipmentModel::DurationDistanceMatrix.
Specifies a duration and distance matrix from visit and vehicle start
locations to visit and vehicle end locations.
(::String) — Tag defining to which vehicles this duration and distance matrix applies.
If empty, this applies to all vehicles, and there can only be a single
matrix.
Each vehicle start must match exactly one matrix, i.e. exactly one of
their start_tags field must match the vehicle_start_tag of a matrix
(and of that matrix only).
All matrices must have a different vehicle_start_tag.
#vehicle_start_tag=
defvehicle_start_tag=(value)->::String
Parameter
value (::String) — Tag defining to which vehicles this duration and distance matrix applies.
If empty, this applies to all vehicles, and there can only be a single
matrix.
Each vehicle start must match exactly one matrix, i.e. exactly one of
their start_tags field must match the vehicle_start_tag of a matrix
(and of that matrix only).
All matrices must have a different vehicle_start_tag.
Returns

If empty, this applies to all vehicles, and there can only be a single
matrix.
Each vehicle start must match exactly one matrix, i.e. exactly one of
their start_tags field must match the vehicle_start_tag of a matrix
