java.lang.Object

gr.uoa.di.madgik.workflow.adaptor.utils.jdl.JDLDAGExtractor

public class JDLDAGExtractor
extends Object

The Class JDLDAGExtractor operates on a previously extracted map of the keys and their respective values contained in the provided JDL description. The extractor will scan through the map for known keys and process their respective values to populate the produced ParsedJDLInfo. The known keys which the extractor looks for in the provided map are the following: - ParsedJDLInfo.KnownKeys.ParsingMode (optional) - ParsedJDLInfo.KnownKeys.Max_Running_Nodes (optional) - ParsedJDLInfo.KnownKeys.Rank (optional) - ParsedJDLInfo.KnownKeys.Requirements (optional) - ParsedJDLInfo.KnownKeys.NodesCollocation (optional) - ParsedJDLInfo.KnownKeys.ConnectionMode (optional) - ParsedJDLInfo.KnownKeys.Nodes (optional) - ParsedJDLInfo.KnownKeys.Dependencies (optional) For every Node described in the DAG, the ParsedJDLInfo.KnownKeys.Description value is extracted and is used to populate a new ParsedJDLInfo, contained in the ParsedJDLInfo produced by the JDLDAGExtractor, using the JDLJobExtractor. The Keys are expected to be found with the exact capitalization that is defined for each key. The dependency list retrieve by the ParsedJDLInfo.KnownKeys.Dependencies are expected to be defined in pairs. No inner list expression is supported. The ParsedJDLInfo.KnownKeys.InputSandbox is not supported at the level of DAG. This means that every node needs to define its own Input Sandbox and cannot reference the global one. TODO: - Fix capitalization requirement - Support inner list definition of dependencies
