The polling in above graphic is provided by a file order source setting in the job chain.
Example Job to Create a Result Set.
This job is creating a result set. A A result set contain the names of all files which are selected as specified by the filter criteria. The content of the result set is returned as a parameter, but can be written to a file, too.
Parameters, which are useful for creating a result-set, are:

This job can be used standalone, as a single job, or as an order driven job in a jobchain as a jobchain node. Parameters are respectively accepted as job- or as order-parameters.
A job can process multiple parameters that are analysed analyzed when the job starts. Parameters are defined in the configuration of the job or of the order. Parameters can also be submitted by API methods, as well. Parameters are optional or mandatory and may contain default values.
This job is creating a result set. A result set contain the names of all files which are selected as specified by the filter criteria. The content of the result set is returned as a parameter, but can be written to a file, too.
