Class FakeRtsa

java.lang.Object

de.iip_ecosphere.platform.kiServices.rapidminer.rtsaFake.FakeRtsa

public class FakeRtsa
extends java.lang.Object

A very simple RTSA fake server as we are not allowed to publish RTSA. The FakeRTSA reads its functionality out of a spec.yml file in the deployment.jar (packaged into a zip, there into folder home/deployments). The spec.yml is intended to easily adjust the behavior rather than doing coding/requiring a build process. Format of the spec.yml: path: <String> mappings: <String>: <String> The path indicates the desired REST path/endpoint attached to the base path "services/" The mappings relate a field name to a function specification. As function specification, we currently offer PASS, SKIP, RANDOM_BOOLEAN, RANDOM_PROBABILITY, RANDOM_SELECT(args) whereby args are separated by comma, may be strings. Fields not given in the data but specified in spec.yml will be added to the output based on the given (random) data specification. For new classes in this package, please consider that the POM is doing a selective packaging for Fake*.class so either classes are contained/nested or their names start with Fake!

                                                                   java.lang.String defaultPath)

Loads the unpacked deployments.

Parameters:

baseDir - the base directory

defaultPath - the default path if no one is specified

Returns:

the deployments

lines
