Method Detail

combineWorkflows

public static void combineWorkflows(WorkflowJson targetOriginalWorkflow,
                                    WorkflowJson overlayWorkflow)

Combines (merges) two workflow objects. Merging is based on the name attributes of subtypes. For example, if a ProcessingRuleJson has a name "Metadata Processing" and the overlayWorkflow also has a ProcessingRuleJson with the same name ("Metadata Processing"), properties of the processing rule in the overlay will be merged into the original workflow. Merging will either extend the original workflow or will override values in the original object. If a particular value is not set in the original workflow, it will be added. If it exists - it will be overridden. There is an option to force complete replacement behaviour. ProcessingRuleJson and ActionJson have MergeMode property. If this property is set to REPLACE, values in matched (by name) in Processing Rule or Action will replace values in the targetOriginalWorkflow. MergeMode value for both objects defaults to MERGE.

Parameters:

targetOriginalWorkflow - a base workflow to which apply the overrides and / or extensions

overlayWorkflow - a workflow object with overrides and / or extensions
