Package net.sourceforge.pmd

Class PMD

java.lang.Object

net.sourceforge.pmd.PMD

public class PMD
extends java.lang.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 java.util.List<DataSource> getURIDataSources(java.lang.String uriString)
                                                    throws PMDException

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

Parameters:

uriString - the URI to parse
