public abstract class AbstractAccumulatingRenderer
extends AbstractRenderer

Abstract base class for Renderer implementations which only produce output once all source files are processed. Such Renderers use working memory proportional to the number of violations found, which can be quite large in some scenarios. Consider using AbstractIncrementingRenderer which can use significantly less memory. Subclasses should implement the end() method to output the report.

Constructor Detail

AbstractAccumulatingRenderer

public AbstractAccumulatingRenderer(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

end

public abstract void end()
                  throws IOException

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

Throws:

IOException
