public DigesterLoader()
Method Detail

createDigester

public static Digester createDigester(org.xml.sax.InputSource rulesSource)
Creates a new digester and initializes it from the specified InputSource

Parameters:
rulesSource - load the xml rules from this InputSource
Returns:
a new Digester initialized with the rules

createDigester

public static Digester createDigester(org.xml.sax.InputSource rulesSource,
                                      Digester rulesDigester)
Creates a new digester and initializes it from the specified InputSource. This constructor allows the digester to be used to load the rules to be specified. This allows properties to be configured on the Digester instance before it is used.

Parameters:
rulesSource - load the xml rules from this InputSource
rulesDigester - digester to load the specified XML file.
Returns:
a new Digester initialized with the rules

createDigester

public static Digester createDigester(java.net.URL rulesXml)
Creates a new digester and initializes it from the specified XML file

Parameters:
rulesXml - URL to the XML file defining the digester rules
Returns:
a new Digester initialized with the rules

createDigester

public static Digester createDigester(java.net.URL rulesXml,
                                      Digester rulesDigester)
Creates a new digester and initializes it from the specified XML file. This constructor allows specifing a rulesDigester to do the XML file loading; thus no matter the XML files is packed into a jar, a war, or a ear, the rulesDigester can always find the XML files with properly set ClassLoader.

Parameters:
rulesXml - URL to the XML file defining the digester rules
rulesDigester - digester to load the specified XML file.
Returns:
a new Digester initialized with the rules
