Class SamplerData<G extends GtuData>

java.lang.Object
org.djutils.data.Table
org.opentrafficsim.kpi.sampling.SamplerData<G>
Type Parameters:
G - gtu data type
All Implemented Interfaces:
Iterable<org.djutils.data.Row>, org.djutils.base.Identifiable
public class SamplerData<G extends GtuData> extends org.djutils.data.Table
SamplerData is a storage for trajectory data. Adding trajectory groups can only be done by subclasses. This is however not a guaranteed read-only class. Any type can obtain the lane directions and with those the coupled trajectory groups. Trajectories can be added to these trajectory groups. Data can also be added to the trajectories themselves.
