All Superinterfaces:

ProblemFactory

public interface PipelineProblems
extends ProblemFactory

Factory for producing problems that involve pipelines or pipeline steps. See also ArgsProblems for dealing with step argument problems.

Method Details

get

static PipelineProblems get()

cannotRealize

Problem cannotRealize(StepDefinition step)

Assigned to the result of as the parent problem. Produces message: "Could not realize "

cannotRealize

Problem cannotRealize(Class<?> thing)

failedDependencies

Problem failedDependencies(String dependentStepName)

Step could not be realized because of failed dependencies

namedInputUnknown

Problem namedInputUnknown(Step step,
 String inputName,
 List<String> supportedInputs)

Attempt to chain to a named input that doesn't exist on the target step. Produces message: has no input named ''. Known input names are

executionFailed

Problem executionFailed()

Problem associated with an ExecutionException

outOfStorage

Problem outOfStorage(String storageLocation,
 long amountFree)

Attached to an OutOfStorageException

cycleDetected

Problem cycleDetected(String offendingLink,
 SourceLocation linkLocation,
 String offendingDeclaration,
 SourceLocation firstOccurence)

There was a cycle in your pipeline

Parameters:

offendingLink - the link in the pipeline that when added caused the cycle, e.g. foo() -> bar()

linkLocation - the line the link was added on, uses the location of the -> token

offendingDeclaration - The -> and step declaration on the rhs of the link which if removed will remove the cycle

firstOccurence - the place where we first saw the offendingDeclaration

stepRedefinition

Problem stepRedefinition(String stepName,
 SourceLocation originalLocation,
 SourceLocation redefinedAt)

The pipeline contains two steps with the same name.

Parameters:

stepName - the name that is being reused

originalLocation - the line number that stepName was first defined

redefinedAt - the line number that is attempting to redefine stepName
