Interface ExecutionContext

All Superinterfaces:
AutoCloseable
public interface ExecutionContext extends AutoCloseable

Various bits associated with the realization and execution of a pipeline

  • Method Details

    • getEngine

      Engine getEngine()

    • getProject

      Project getProject()

    • getExpressionRealizer

      default ExpressionRealizer getExpressionRealizer()

    • getBindingContext

      BindingContext getBindingContext()

    • getMetricRegistry

      com.codahale.metrics.MetricRegistry getMetricRegistry()

    • getPipelineExecutor

      PipelineExecutor getPipelineExecutor()

    • getTempDirectory

      Path getTempDirectory()
      Returns:
      a directory that can be used for temporary files for the duration of this execution context.

    • close

      void close()

      Closes the execution context and removes any temporary resources created within it.

      Specified by:
      close in interface AutoCloseable

    • getRealizationContext

      RealizationContext getRealizationContext()

      Returns a RealizationContext bound to the ExecutionContext for use when realizing expressions for use within this ExecutionContext.

      At the moment, this is just a handy accessor, but in the future, any resources used or created during realization might be managed or dependent on the execution context, so in time we want to make sure that any expressions realized for use within a pipeline use this context, instead of creating their own 'one off' context object.

    • getPipelineRealizer

      PipelineRealizer getPipelineRealizer()
      Returns:
      a PipelineRealizer that can be used to realize a pipeline.

    • realize

      default RealizedPipeline realize(PipelineDeclaration ast, Map<String,Expression> pipelineParameters)

      Convenience method for realizing a pipeline with parameters using this ExecutionContext. See PipelineRealizer for more details

    • realize

      default RealizedPipeline realize(PipelineDeclaration ast)

      Convenience method for realizing a pipeline with no parameters using this ExecutionContext. See PipelineRealizer for more details

    • getProblemSink

      ProblemSink getProblemSink()
      Returns:
      a ProblemSink to direct any warnings encountered

    • getOriginalContext

      ExecutionContext getOriginalContext()
      Returns:
      the original execution context that this one is based on (in the case of wrapped contexts)
