Input and Output Parameters

The following types of input and output parameters can be used by the components:

  • Pages: Some components such as the navigation sequence (Sequence) component return a page as result. A Page element can be used by other components to extract data from it or to continue a navigation sequence from that point.

  • Records: Other components (e.g. the Record Constructor) return a structured group of information (in this example, this may be the structured representation of an information item).

  • Lists of records: ITPilot allows for some components (e.g. the Extractor component) to return lists of registers at their output or to accept them at their input.

  • Values: Other components can return simple values at their output such as the Expression component. Simple values can be of the following types: string, integer, date, double, long, float, url, boolean.

  • Browsers: Special simple values used by the browser persistence management components (see section Create Persistent Browser).

The input parameters are selected by mean of the drop-downs, which contain all the output variables whose type is compatible with the type of the input parameter (note that an input parameter can accept values of a single type or several types). It is also possible to type text in these drop-down lists, to search the variables starting with the typed text. This is especially useful in processes containing a lot of components (and therefore, a lot of output variables that can be used as input parameters in other components).
