Process.Plugin
is a built-in interface that allows you to process data within
your organization and pass it to a specified flow. The interface exposes
Apex as a service, which accepts
input values and returns output back to the flow.
When you define an Apex
class that implements the Process.Plugin interface in
your organization, the Cloud Flow Designer displays the Apex class
in the Palette.
Process.Plugin has these top-level classes.
-
Process.PluginRequest passes input parameters from the class that
implements the interface to the flow.
-
Process.PluginResult returns output parameters from the class that
implements the interface to the flow.
-
Process.PluginDescribeResult passes input parameters from a flow to
the class that implements the interface. This class determines the input parameters and
output parameters needed by the Process.PluginResult plug-in.
When you write Apex unit
tests, instantiate a class and pass it into the interface invoke method. To pass in the parameters that the system needs, create a map and
use it in the constructor. For more information, see Using the Process.PluginRequest Class.
