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 InputSourcerulesDigester
- 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 rulesrulesDigester
- digester to load the specified XML file.- Returns:
- a new Digester initialized with the rules
-
load
public static java.lang.Object load(java.net.URL digesterRules, java.lang.ClassLoader classLoader, java.net.URL fileURL) throws java.io.IOException, org.xml.sax.SAXException, DigesterLoadingException
Given the digester rules XML file, a class loader, and an XML input file, this method parses the input file into Java objects. The class loader is used by the digester to create the Java objects.- Parameters:
digesterRules
- URL to the XML document defining the digester rulesclassLoader
- the ClassLoader to register with the digesterfileURL
- URL to the XML file to parse into Java objects- Returns:
- an Object which is the root of the network of Java objects created by digesting fileURL
- Throws:
java.io.IOException
org.xml.sax.SAXException
DigesterLoadingException
-

- the ClassLoader to register with the digesterinput
- InputStream over the XML file to parse into Java objects- Returns:
- an Object which is the root of the network of Java objects created by digesting fileURL
