Class DDFactory

java.lang.Object

org.netbeans.modules.schema2beans.DDFactory

public class DDFactory
extends Object

This class provides a dynamic mechanism to instantiate schema2beans graphs. The first and most common way to instantiate a schema2beans graph is to call the createGraph() method on the root class of the generated schema2beans classes. It might happen that the code that whish to instantiate a schema2beans graph doesn't have or know about the class of the schema2beans root element. Such code should be able to say 'I want to instantiate a schema2beans graph', and I know that it is named 'graphName'. This is what the register and create methods are performing. The code that knows about the schema2beans classes can register the class root node using some public name. Then, other part of the code can instantiate a schema2beans graph using simply the public name (@see create). This class also provide some utility methods to dump the content of a DOM tree as a String (@see XmlToString).

Method Detail

create

public static BaseBean create(InputStream in,
                              String rootName)
                       throws Schema2BeansException

Create the proper DD bean object graph depending on the document type of the XML document specified as an input stream.

Parameters:

in - the XML document is passed as an input stream.

Returns:

BaseBean is the base object for all DD beans.

Throws:

Schema2BeansException

register

public static void register(String name,
                            String className)
                     throws ClassNotFoundException

Register the root bean to use for a DTD document root name. Use the default class loader, then tries to use the String name object class loader. The name of the graph can be any string (it doesn't have to be the root element name)

Parameters:

name - entry name of this graph registry

className - class name (package and class name) to use in order to instantiate the schema2beans graph. This should be the class name of the root of the schema2beans generated classes.

Throws:

ClassNotFoundException

register

public static void register(String name,
                            Class clazz)

Register the root bean to use for a DTD document root name. Use the default class loader, then tries to use the String name object class loader. The name of the graph can be any string (it doesn't have to be the root element name)

Parameters:

name - entry name of this graph registry

clazz - class to use in order to instantiate the schema2beans graph. This should be the class of the root of the schema2beans generated classes.

XmlToString

public static String XmlToString(Node n)

Dump the whole content of a DOM tree as a String

XmlToString

public static String XmlToString(Node n,
                                 int depth)

Dump the content of a DOM tree as a String. This methods only recurses for the specified depth.

XmlToString

public static String XmlToString(Node n,
                                 int depth,
                                 String filter)

Dump the content of a DOM tree as a String. This methods only recurses for the specified depth and only prints elements that match the filter.
