public abstract class AbstractIncrementingRenderer
extends AbstractRenderer

Abstract base class for Renderer implementations which can produce output incrementally for RuleViolations as source files are processed. Such Renderers are able to produce large reports with significantly less working memory at any given time. Variations in the delivery of source file reports are reflected in the output of the Renderer, so report output can be different between runs. Only processing errors and suppressed violations are accumulated across all files. These are intended to be processed in the end() method.

Field Summary

protected List<Report.ProcessingError>	errors Accumulated processing errors.
protected List<Report.SuppressedViolation>	suppressed Accumulated suppressed violations.

AbstractIncrementingRenderer

public AbstractIncrementingRenderer(String name,
                                    String description)

Method Detail

start

public void start()
           throws IOException

This method is called before any source files are processed. The Renderer will have been fully initialized by the time this method is called, so the Writer and other state will be available.

Throws:

IOException

startFileAnalysis

public void startFileAnalysis(DataSource dataSource)

This method is called each time a source file is processed. It is called after Renderer.start(), but before Renderer.renderFileReport(Report) and Renderer.end(). This method may be invoked by different threads which are processing files independently. Therefore, any non-trivial implementation of this method needs to be thread-safe.

Parameters:

dataSource - The source file.

renderFileReport

public void renderFileReport(Report report)
                      throws IOException

Render the given file Report. There may be multiple Report instances which need to be rendered if produced by different threads. It is called after Renderer.start() and Renderer.startFileAnalysis(DataSource), but before Renderer.end().

Parameters:

report - A file Report.

Throws:

IOException

Report

renderFileViolations

public abstract void renderFileViolations(Iterator<RuleViolation> violations)
                                   throws IOException

Render a series of RuleViolations.

Parameters:

violations - The iterator of violations to render.

Throws:

IOException

end

public void end()
         throws IOException

This method is at the very end of the Rendering process, after Renderer.renderFileReport(Report).

Throws:

IOException
