setKeys
The key names to pull out of the execution context or job parameters, if they exist. If a key doesn't exist in the execution context then the job parameters from the enclosing job execution are tried, and if there is nothing there either then no parameter is extracted. Key names ending with(long)
,(int)
,(double)
,(date)
or(string)
will be assumed to refer to values of the respective type and assigned to job parameters accordingly (there will be an error if they are not of the right type). Without a special suffix in that form a parameter is assumed to be of type String.- Parameters:
keys
