The following information is derived from the plugin description.

This plugin demonstrates how to create and register an EngineFactory which is then used by default for all reports.

A custom EngineFatory is required to programatically set up a report engine e.g. using custom parameters that are not supported by the default implementation. That allows to fully customize input parameters resulting in a correctly configured engine. You can e.g. use encrypted parameters that only your EngineFactory can decrypt for example selecting a report file that is unknown to the end-user or make sure that only certain datasources are used in reporting.

Note: This plugin is a reporting sample that can be used as a starting point for custom implementation. You can download and install the plugin as is, but it is recommended to to download, unpack and check the content first. The plugin sample includes the source code as well as README files with further information and instructions. The sample plugin is also included in the SDKs.
