PipelineBlock.BlockEvaluationContext

Enclosing interface:: PipelineBlock

public static interface PipelineBlock.BlockEvaluationContext

A PipelineBlock.BlockEvaluationContext is an "instance" for evaluating an incoming AlarmEvent against a PipelineBlock's configuration.

An AlarmPipeline only has one instance of each PipelineBlock, but spawns short-lived PipelineBlock.BlockEvaluationContexts for each block as inputs pass through.

Method Details
- evaluate
  
  void evaluate()
  
  Evaluate this PipelineBlock's input against its configuration parameters. When done evaluating, places the next block's PipelineBlock.BlockEvaluationContext onto the evaluation queue.
  Implementations should take care to check if an AlarmEvent has met DropoutConditions or the pipeline has been stopped before continuing with evaluation.
- pipelineStopped
  
  void pipelineStopped()
  
  The AlarmPipeline this block is running in has been stopped. Abandon evaluation if possible.
