Class ConfigParser

java.lang.Object

org.jvnet.hk2.config.ConfigParser

public class ConfigParser
extends Object

Parses configuration files, builds

invalid reference

Inhabitant

s, and add them to

invalid reference

Habitat

.

This class also maintains the model of various elements in the configuration file.

This class can be sub-classed to create a ConfigParser with a custom non-standard behavior.

invalid reference

Habitat

as

invalid reference

Inhabitant

s.

handleElement

protected Dom handleElement(XMLStreamReader in,
 DomDocument document,
 Dom parent)
                     throws XMLStreamException

Parses a whole XML tree and builds a Dom tree.

This is the entry point for the root element of a configuration tree.

Parameters:

in - pre-condition: 'in' is at the start element. post-condition: 'in' is at the end element.

document - The document that we are building right now. Newly created Dom will belong to this document.

parent - The parent element

Returns:

Null if the XML element didn't yield anything (which can happen if the element is skipped.) Otherwise fully parsed valid Dom object.

Throws:

XMLStreamException

handleElement

protected Dom handleElement(XMLStreamReader in,
 DomDocument document,
 Dom parent,
 ConfigModel model)
                     throws XMLStreamException

Parses a whole XML tree and builds a Dom tree, by using the given model for the top-level element.

This is the entry point for recursively parsing inside a configuration tree. Since not every element is global, you don't always want to infer the model just from the element name (as is the case with handleElement(XMLStreamReader, DomDocument, Dom).

Parameters:

in - pre-condition: 'in' is at the start element. post-condition: 'in' is at the end element.

document - The document that we are building right now. Newly created Dom will belong to this document.

parent - The parent element

Returns:

Null if the XML element didn't yield anything (which can happen if the element is skipped.) Otherwise fully parsed valid Dom object.

Throws:

XMLStreamException
