Method Detail

buildWorkflow

public static String buildWorkflow(ServicesEdge[] edges,
                                   String mobyEndpoint,
                                   Properties props)
                            throws MobyException

Creates a workflow definition (an XML string known as 'scufl' or 'xscufl') from the set of graph edges. The definition includes also pointer to a BioMoby registry where the services (used by graph edges) are registered.

Parameters:

edges - represent services and their connectors in the created graph; some edges may be of type DataServiceEdge (which is a subclass of ServicesEdge) - those represent a special type of connection between a service and an input or ouput data type; the graph represented by these edges should not have cycles and should not have forking and merging branches

props - are some properties that can influence how the workflow definition will look like; see the property names elsewhere in this API what properties are understood

Returns:

a string with a scufl workflow definition

Throws:

MobyException
