Topic: Passages of states of object

There is an object the Order. At it can be the order of 30 statuses. Is  where the administrator can span the order from any status in any status. That is if all to paint on each combination that it turns out   and a lot of duplication turns out. For certain there are checked templates for the such? What?

If from one status passage in strict a limited number of statuses and a question only in it is possible, it is possible to use the associative arrays (std:: map <enum, enum>), setting steams a key-> value for each of possible changes of the status of the order or a key-> set of statuses (std:: map <enum, std:: set <enum>>)

The table almost for certain static, for static tables very well approaches an old kind array.

Even if they are stored somewhere in basis, it is possible to do conversion at saving/loading of the data.

Modify business process that such brothel was not. And then at you will be drawn beautiful state machine, and shaft  that them , all as is necessary.

Re: Passages of states of object

If you want ,  a heap of switches, in one place, it that is necessary. And in an ideal do in basis a label with possible passages but if you will be fond, you will write Jira.

(Clever men who write stored procedures for databases, but not on SQL, and directly in the compiled code through a prism any ORM Here get out, and declare that OOP does not work and meets only in textbooks, but I do not recommend them to listen.)

Such variant yet was not: if it is possible to reorganize states in the form of states and  for implementation of states we use a pattern state from gof, and for  - state machine.

Found implementation but here the moment what it is not clear. Here if we follow an example from the link There is a jump table at me there is a passage from Paused in Exit.

The object from a state 1 can pass in 20 states Object from a state 2 can pass in 20 states... The Object from a state 20 can pass in 20 states at passage from a state 20 in a state 1 and at passage from a state 19 in a state 1 will be the identical logic, except one method (20 => 19) how to issue?

S> probably Stejt approaches but how to envelop? Did not understand a question. Imagine a label, where across - input influences, on a vertical - a current state, and in cells - a new state. To issue it it is possible on a miscellaneous, including attracting . the general all it is defined by pair: the current state - input influence, in the resulted example is class StateTransition, for each such pair we define a new state and if needed we pass. I.e. pass we can as us takes in head.

Passages are possible from any state in any, i.e. all depends from the set corrected. Any restrictions are not present. Though there are types of states of type finite - if there got, remains only there.  specifies in itself.
