Class PMD

java.lang.Object

net.sourceforge.pmd.PMD

public class PMD
extends Object

This is the main class for interacting with PMD. The primary flow of all Rule process is controlled via interactions with this class. A command line interface is supported, as well as a programmatic API for integrating PMD with other software such as IDEs and Ant.

Constructor Detail

PMD

public PMD()

Create a PMD instance using a default Configuration. Changes to the configuration may be required.

PMD

public PMD(PMDConfiguration configuration)

Create a PMD instance using the specified Configuration.

Parameters:

configuration - The runtime Configuration of PMD to use.

Method Detail

getURIDataSources

public static List<DataSource> getURIDataSources(String uriString)
                                          throws PMDException

Parses the given string as a database uri and returns a list of datasources.

Parameters:

uriString - the URI to parse

Returns:

list of data sources

Throws:

PMDException - if the URI couldn't be parsed

DBURI

parserFor

public static Parser parserFor(LanguageVersion languageVersion,
               PMDConfiguration configuration)

Helper method to get a configured parser for the requested language. The parser is configured based on the given PMDConfiguration.

Parameters:

languageVersion - the requested language

configuration - the given configuration

Returns:

the pre-configured parser

setupReport

public static Report setupReport(RuleSets rs,
                 RuleContext ctx,
                 String fileName)

Create a report, filter out any defective rules, and keep a record of them.

Parameters:

rs - the rules

ctx - the rule context

fileName - the filename of the source file, which should appear in the report

Returns:

the Report

getConfiguration

public PMDConfiguration getConfiguration()

Get the runtime configuration. The configuration can be modified to affect how PMD behaves.

Returns:

The configuration.

PMDConfiguration

getSourceCodeProcessor

public SourceCodeProcessor getSourceCodeProcessor()

Gets the source code processor.

Returns:

SourceCodeProcessor

doPMD

public static int doPMD(PMDConfiguration configuration)

This method is the main entry point for command line usage.

Parameters:

configuration - the configure to use

Returns:

number of violations found.

newRuleContext

public static RuleContext newRuleContext(String sourceCodeFilename,
                         File sourceCodeFile)

Creates a new rule context, initialized with a new, empty report.
