nz.org.riskscape.wizard.bld.change.AppendStepChange
All Implemented Interfaces:
PipelineChange
public class AppendStepChange extends BasePipelineChange<nz.org.riskscape.pipeline.ast.StepChain>

Change for appending a StepChain to a StepChain, elongating it (not creating a branch)

  • Constructor Details

    • AppendStepChange

      public AppendStepChange(Answer answer, String source)

  • Method Details

    • getSource

      protected String getSource()
      Description copied from class: BasePipelineChange

      TODO maybe break this up in to something else?

      Specified by:
      getSource in class BasePipelineChange<nz.org.riskscape.pipeline.ast.StepChain>
      Returns:
      the source code that was assembled to be parsed in to a PipelineDeclaration

    • validateParsedSegment

      protected nz.org.riskscape.pipeline.ast.StepChain validateParsedSegment(nz.org.riskscape.pipeline.ast.PipelineDeclaration declaration)

      Validate and extract the relevant bit of AST from the parsed pipeline - relevance is as decided by the change and is mostly a convenience / reminder to do this step

      Specified by:
      validateParsedSegment in class BasePipelineChange<nz.org.riskscape.pipeline.ast.StepChain>
      Returns:
      the interesting bit of the pipeline, e.g. a single step, a step chain, whatever
      Throws:
      BadPipelineChange

    • updateAst

      protected nz.org.riskscape.pipeline.ast.PipelineDeclaration updateAst(IncrementalBuildState state, nz.org.riskscape.pipeline.ast.PipelineDeclaration astSegment, nz.org.riskscape.pipeline.ast.StepChain validated)
      Description copied from class: BasePipelineChange

      Build a new AST that is the result of this change

      Specified by:
      updateAst in class BasePipelineChange<nz.org.riskscape.pipeline.ast.StepChain>
      Parameters:
      state - the previous build state that we are building upon
      astSegment - the segment that was parsed and validated. This is not the previous state's ast.
      validated - the chunk of the parsed segment that the validate routine method returned - this is often the node of interest that ultimately gets added to the previous state's ast
      Returns:
      a pipeline ast to be used in the next IncrementalBuildState
