Interface PipelineChange

All Known Implementing Classes:

AppendJoinChange, AppendStepChange, BasePipelineChange, MultipleChanges, NoChange, SimpleChange, StartChainChange

public interface PipelineChange

An operation that can return a possibly new IncrementalBuildState in response to an Answer. The returned build state reflects the change.

Method Details

chainStep

static IncompletePipelineChange chainStep(String pipelineFragment,
 Object... args)

Chains a StepChain to an existing StepChain, appending the chain to the last implicit step

newChain

static IncompletePipelineChange newChain(String pipelineFragment,
 Object... args)

Add a new StepChain to the pipeline, disconnected from any other StepChains.

simple

static IncompletePipelineChange simple(BiFunction<Answer,IncrementalBuildState,nz.org.riskscape.pipeline.ast.PipelineDeclaration> function)

Returns:

a PipelineChange based on a function that returns a new PipelineDeclaration.

many

static IncompletePipelineChange many(List<IncompletePipelineChange> children)

Returns:

a PipelineChange that is composed of many other changes that get applied on order

many

static IncompletePipelineChange many(IncompletePipelineChange... children)

Returns:

a PipelineChange that is composed of many other changes that get applied on order

noChange

static IncompletePipelineChange noChange()

Returns:

a PipelineChange that does nothing

failed

static IncompletePipelineChange failed(List<nz.org.riskscape.problem.Problem> problems)

Returns:

a PipelineChange that will always fail with the given problems.

make

nz.org.riskscape.problem.ResultOrProblems<IncrementalBuildState> make(IncrementalBuildState currentState)
                                                               throws BadPipelineChangeException

Attempt to create a new IncrementalBuildState for this change

Returns:

a new IncrementalBuildState with this change applied

Throws:

BadPipelineChangeException - if something went wrong that wasn't the user's fault

getAnswer

Answer getAnswer()

Returns:

the Answer that was ultimately responsible for this PipelineChange being introduced. Note that this might not be the only thing that predicated this change, but it is the last thing that caused it (the straw that broke the camel's back, so to speak)

parse

default nz.org.riskscape.pipeline.ast.PipelineDeclaration parse(String pipelineSource)

Helper method to attempt parsing some pipeline dsl source, wrapping any ParseExceptions in a BadPipelineChangeException

getQuestionSet

default QuestionSet getQuestionSet()

Returns:

the QuestionSet that was responsible for this change

getQuestion

default Question getQuestion()

Returns:

the Question that was responsible for this change
