Dummy example of looping

Created: 2010-01-27 15:52:50      Last updated: 2013-10-08 11:24:47

Example of looping over asynchronous services. The dummy beanshell scripts represents the operations of an asynchronous submit-status-results style service, such as EBI's InterProScan and NCBI Blast.

createJob creates a temporary file with the content "0". Filename retuirned as a "job ID".

checkStatus reads the job, and return state "RUNNING" as long as the content is less than 10, increasing the number for each call. (As no actual job is being run)

getResults reads the file content, with the condition 'Run after checkStatus'.

In Details->Advanced for checkStatus you can check the loop condition for checkStatus, which says it will loop as long as the output 'state' is equal to 'RUNNING' - with a 0.5s delay.

Thus when executing this workflow, checkStatus will be called repeatedly, and finally the 'result' should be '10' and 'state' should be 'COMPLETE'.
