createRawSubsystemDescription

Creates a new SubsystemDescription without any ParameterDescription creation. The object is not registered in the database since it is to be populated by ParameterDescription objects.

To populate the descriptions get the base descriptions from the Subsystemdescription by calling a version of getBaseParameters or getParameterDescriptions and generate the descriptions from these bases.

Parameters:

subsystemName -

tag -

user -

version -

configurationData -

dataFlavour -

Returns:

creates a new SubsystemDescription populated with "empty" ParameterDescriptions. The object is not in the database since the list of descriptions should be modified first.

TODO: this method will be modified to populate with parameterDescriptions that are not necessarily empty.

filter -

Returns:

createSubsystemDescriptionCopy

public static SubsystemDescription createSubsystemDescriptionCopy(SubsystemDescription desc)

Parameters:

desc -

Returns:
