Interface Renderer

All Superinterfaces:

PropertySource

All Known Implementing Classes:

AbstractAccumulatingRenderer, AbstractIncrementingRenderer, AbstractRenderer, CodeClimateRenderer, CSVRenderer, EmacsRenderer, EmptyRenderer, HTMLRenderer, IDEAJRenderer, SummaryHTMLRenderer, TextColorRenderer, TextPadRenderer, TextRenderer, VBHTMLRenderer, XMLRenderer, XSLTRenderer, YAHTMLRenderer

public interface Renderer
extends PropertySource

This is an interface for rendering a Report. When a Renderer is being invoked, the sequence of method calls is something like the following:

1. Renderer construction/initialization
2. setShowSuppressedViolations(boolean)
3. setWriter(Writer)
4. start()
5. startFileAnalysis(DataSource) for each source file processed
6. renderFileReport(Report) for each Report instance
7. end()

An implementation of the Renderer interface is expected to have a default constructor. Properties should be defined using the PropertySource.definePropertyDescriptor(PropertyDescriptor) method. After the instance is created, the property values are set. This means, you won't have access to property values in your constructor.

Method Summary

Modifier and Type	Method and Description
java.lang.String	defaultFileExtension() Return the default filename extension to use.
void	end() This method is at the very end of the Rendering process, after renderFileReport(Report).
void	flush()
java.lang.String	getDescription() Get the description of the Renderer.
java.lang.String	getName() Get the name of the Renderer.
java.io.Writer	getWriter() Get the Writer for the Renderer.
boolean	isShowSuppressedViolations() Get the indicator for whether to show suppressed violations.
void	renderFileReport(Report report) Render the given file Report.
void	setDescription(java.lang.String description) Set the description of the Renderer.
void	setName(java.lang.String name) Set the name of the Renderer.
void	setShowSuppressedViolations(boolean showSuppressedViolations) Set the indicator for whether to show suppressed violations.
void	setWriter(java.io.Writer writer) Set the Writer for the Renderer.
void	start() This method is called before any source files are processed.
void	startFileAnalysis(DataSource dataSource) This method is called each time a source file is processed.

Method Detail

getName

java.lang.String getName()

Get the name of the Renderer.

Returns:

The name of the Renderer.

setName

void setName(java.lang.String name)

Set the name of the Renderer.

Parameters:

name - The name of the Renderer.

getDescription

java.lang.String getDescription()

Get the description of the Renderer.

Returns:

The description of the Renderer.

defaultFileExtension

java.lang.String defaultFileExtension()

Return the default filename extension to use.

Returns:

String

setDescription

void setDescription(java.lang.String description)

Set the description of the Renderer.

Parameters:

description - The description of the Renderer.

isShowSuppressedViolations

boolean isShowSuppressedViolations()

Get the indicator for whether to show suppressed violations.

Returns:

true if suppressed violations should show, false otherwise.

setShowSuppressedViolations

void setShowSuppressedViolations(boolean showSuppressedViolations)

Set the indicator for whether to show suppressed violations.

Parameters:

showSuppressedViolations - Whether to show suppressed violations.

getWriter

java.io.Writer getWriter()

Get the Writer for the Renderer.

Returns:

The Writer.

setWriter

void setWriter(java.io.Writer writer)

Set the Writer for the Renderer.

Parameters:

writer - The Writer.

start

void start()
    throws java.io.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:

java.io.IOException

startFileAnalysis

void startFileAnalysis(DataSource dataSource)

This method is called each time a source file is processed. It is called after start(), but before renderFileReport(Report) and 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

void renderFileReport(Report report)
               throws java.io.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 start() and startFileAnalysis(DataSource), but before end().

Parameters:

report - A file Report.

Throws:

java.io.IOException

See Also:

Report

end

void end()
  throws java.io.IOException

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

Throws:

java.io.IOException

flush

void flush()
    throws java.io.IOException

Throws:

java.io.IOException
