Shark interface 1 Analysis (2)-suspend Process

 

SharkProcess suspension process

1) Get the execution Manager interface

Executionadministration Ea = shark. getinstance (). getadmininterface () .. getexecutionadministration ();

2) connect to the Workflow Server

EA. Connect (username, password, enginename, scope );

3) use the process instance number to obtain the process

Wfprocess WFP = EA. getprocess (processinskey );

4) pending process

WFP. Suspend ();

The following is a detailed analysis of pending operations.

// The status cannot be suspended

If(State (T). Equals (sharkconstants. state_open_not_running_suspended )){

Throw NewAlreadysuincluded ("the process is already susponded ");

}

// The running process can be suspended.

If(State (T). startswith (sharkconstants. stateprefix_open_not_running )){

Throw NewNotrunning ("the process is not in the running state ");

}

Try{

// Change the status

Change_state (T, sharkconstants. state_open_not_running_suspended );

 

Iterator it = getactiveactivities (T). iterator ();

While(It. hasnext ()){

Wfactivityinternal act = (wfactivityinternal) it. Next ();

// Perform the same operation on each activity

If(Act. State (T). startswith (sharkconstants. stateprefix_open )){

Act. Suspend (t );

}

}

}

5) disconnect

EA. Disconnect ();
