Shark interface 1 analysis (1)-Startup Process

 

SharkProcess initiation process

 

1) locate the Workflow Server

Shark. Configure ("Shark. conf ");

Sharkinterface Si = shark. getinstance ();

2) connect to the Workflow Server

Sharkconnection SC = Si. getsharkconnection ();

SC. Connect (username, PWD, enginename, scope );

3) Production Process

Wfprocess WFP = SC. CreateProcess (pkgid, pdefid );

The sharkconnection object is used to generate a process. The object stores user information and uses user information as the requester of the generated process;

Then, two parameters are used: the package definition ID and the process definition ID to obtain the ID of the Process Manager;

Finally, use the Process Manager to generate a process.

4) start the process

WFP. Start ();

After several rounds of shark jump, the final implementation is in org. enhydra. Shark. wfprocessimpl. The implementation code is as follows:

// Previous exception judgment

// Start time must be later

Startedtime = system. currenttimemillis ();

// Change the status

Change_state (T, sharkconstants. state_open_running );

// Activate the timer

This. Activatelimitagent (t );

// Drive the process

Run (t,Null);

5) disconnect

Disconnect (SC );

ReturnWFP. Key ();
