Method Details

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

validateParsedSegment

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

Description copied from class: BasePipelineChange

Validate that the parsed pipeline segment is ok to use in this kind of change.

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

toString

public String toString()

Overrides:

toString in class BasePipelineChange<nz.org.riskscape.pipeline.ast.StepChain>

getSource

public 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
