public interface PipelineComponent

This is a component used in a pipeline. If the environment has some configuration for this component setConfiguration(Map) is called as the first step. After the component has been added to pipeline, setup(Map) is called before the pipeline is executed. When the pipeline is finished or if any error occurred finish() is called.

Method Summary

void	finish() This method is called after pipeline run - regardless if the run was successful or an exception was thrown.
void	setConfiguration(Map<String,? extends Object> configuration) Pass component specific configuration parameters to the pipeline component in a generic way.
void	setup(Map<String,Object> parameters) The shared object map for this pipeline run.

Method Detail

finish

void finish()

This method is called after pipeline run - regardless if the run was successful or an exception was thrown.

setConfiguration

void setConfiguration(Map<String,? extends Object> configuration)

Pass component specific configuration parameters to the pipeline component in a generic way. This is useful in environments that automatically assemble pipelines with their components and can't use the components constructors or setters.

Parameters:

configuration - The Map of configuration parameters.

setup

void setup(Map<String,Object> parameters)

The shared object map for this pipeline run.

Parameters:

parameters - A Map of parameters that are available to all PipelineComponents. This is a modifiable map that can be changed by this pipeline component.
