Zygonema journey operating method realizes that the internal state conversion of thread task and the operation of different threads task switch；Described blend
Journey operating method controls the internal conversion of thread task by semaphore, and the operation of different threads task is realized by famous pipeline
Switching, process step is as follows：
The first step, thread task be chosen, wake up after, load semaphore, into init state, make its each member variable assignment
And open up associated internal memory space；
Second step, after the completion of initialization, if without the request of other thread tasks carryings, thread task enters ready state；If there is it
Its thread tasks carrying is asked, and current thread task enters blocked state, switches to the process task for obtaining request；Described line
The request of journey tasks carrying is transmitted by famous pipeline, it is ensured that the mutual exclusion of each thread task run and security；
3rd step, after thread task enters ready state, waits tasks carrying semaphore；If obtaining tasks carrying semaphore,
The functions such as required data, completion treatment, drawing are obtained from main thread, after the completion of task, original state is return；If not obtaining task
Semaphore is performed, then into thread resting state, original place waits；
4th step, if the association related to storage thread task of current thread task, can receive in thread task processes and deposit
Storage line journey task signal, storage thread task is started on backstage, completes data storage；If user sends data storage, and renewal please
Ask, then can block currently stored thread task, re-start data storage.
