  • Constructor Details

    • ChildPipelineBuilder

      public ChildPipelineBuilder(nz.org.riskscape.engine.pipeline.RealizationInput input, nz.org.riskscape.rl.ast.PipelineDeclaration childAst)

      Constructs a new ChildPipelineBuilder for realizing and integrating a child pipeline into a parent pipeline.

      Parameters:
      input - the realization input containing the parent pipeline and context
      childAst - the AST declaration of the child pipeline to be realized

  • Method Details

    • addInputStep

      public void addInputStep(nz.org.riskscape.engine.pipeline.RealizedStep stepFromParent, String stubName)

      Adds an input step from the parent pipeline into the child pipeline by creating a stub step. The stub step mirrors the parent step's output schema but won't be executed during child pipeline realization.

      Parameters:
      stepFromParent - the realized step from the parent pipeline to use as input
      stubName - the name to give the stub step in the child pipeline - this is how the child pipeline will refer to it

    • getChildInputStep

      public nz.org.riskscape.engine.pipeline.RealizedStep getChildInputStep(nz.org.riskscape.engine.pipeline.RealizedStep originalInputStep)

      Retrieves the stub step that was created in the child pipeline for a given parent input step.

      Parameters:
      originalInputStep - the original step from the parent pipeline
      Returns:
      the corresponding stub step in the child pipeline, or null if not found

    • realizeChild

      public nz.org.riskscape.engine.pipeline.RealizedPipeline realizeChild()

      Realizes the child pipeline using the configured AST and input steps. This method must be called after all input steps have been added via addInputStep(nz.org.riskscape.engine.pipeline.RealizedStep, java.lang.String).

      Returns:
      the realized child pipeline, which may contain failures if realization encountered problems

    • combine

      public nz.org.riskscape.engine.pipeline.RealizedPipeline combine()

      Combines the realized child pipeline back into the parent pipeline.

      If the child pipeline failed to realize, a failure step is added to the resulting pipeline to represent those errors

      All child steps are prefixed with the parent step name to ensure unique naming.

      Returns:
      the combined pipeline containing both parent and child steps

    • addWellKnownOutput

      public nz.org.riskscape.engine.pipeline.RealizedPipeline addWellKnownOutput(nz.org.riskscape.engine.pipeline.RealizedStep outputStep, List<nz.org.riskscape.problem.Problem> warnings)

      Adds a step to the combined pipeline named after the input's prototype step (so will have the expected name) for any dependencies that are chained to this step.

    • getCombined

      public nz.org.riskscape.engine.pipeline.RealizedPipeline getCombined()

    • isChildFailed

      public boolean isChildFailed()
      Returns:
      true if the child pipeline has failures.

    • getRebuiltStep

      public nz.org.riskscape.engine.pipeline.RealizedStep getRebuiltStep(nz.org.riskscape.engine.pipeline.RealizedStep childStep)
      Returns:
      the step in combined pipeline that was rebuilt for the child step, i.e. it is the child step, but renamed and in the combined pipeline
