size of the origin state space.
Definition: transitionStructure.h:38
timeType _type
the time type of the structure: discrete or continuous.
Definition: transitionStructure.h:36
virtual transitionStructure * uniformize()=0
Uniformizing a transition structure. The structure should be of continuous time type. The resulting one will be of discrete time type. If uniformization fails, a NULL pointer should be returned. If the origin structure is already of discrete-time type, a copy should be returned.

double _uniformizationRate
value related to the uniformization procedure.
Definition: transitionStructure.h:40
virtual transitionStructure * embed()=0
Embedding a discrete-time transition structure at jump times of a transition structure. The structure should be of continuous time type. The resulting one will be of discrete time type. If embedding fails, a NULL pointer should be returned. If the origin structure is already of discrete-time type, a copy should be returned.
