public class DefaultConfigurationBuilder extends Object
Configurations from XML,
via a SAX2 compliant parser.
XML namespace support is optional, and disabled by default to preserve
backwards-compatibility. To enable it, pass the DefaultConfigurationBuilder constructor the flag true, or pass
a namespace-enabled XMLReader to the DefaultConfigurationBuilder constructor.
The mapping from XML namespaces to Configuration namespaces is pretty straightforward, with one caveat: attribute namespaces are (deliberately) not supported. Enabling namespace processing has the following effects:
xmlns: are interpreted as
declaring a prefix:namespaceURI mapping, and won't result in the creation of
xmlns-prefixed attributes in the Configuration.

Whitespace handling. Since mixed content is not allowed in the
configurations, whitespace is completely discarded in non-leaf nodes.
For the leaf nodes the default behavior is to trim the space
surrounding the value. This can be changed by specifying
xml:space attribute with value of preserve
in that case the whitespace is left intact.

| Constructor Summary | |
|---|---|
| DefaultConfigurationBuilder()
Create a Configuration Builder with a default XMLReader that ignores
namespaces. | |
| DefaultConfigurationBuilder(boolean enableNamespaces)
Create a Configuration Builder, specifying a flag that determines
namespace support.
| |
| DefaultConfigurationBuilder(XMLReader parser)
Create a Configuration Builder with your own XMLReader. | |
| Method Summary | |
|---|---|
| Configuration | build(InputStream inputStream)
Build a configuration object using an InputStream. |
| Configuration | build(String uri)
Build a configuration object using an URI |
| Configuration | build(InputSource input)
Build a configuration object using an XML InputSource object |
| Configuration | buildFromFile(String filename)
Build a configuration object from a file using a filename. |
| Configuration | buildFromFile(File file)

Parameters: enableNamespaces If true, a namespace-aware
SAXParser is used. If false, the default JAXP
SAXParser (without namespace support) is used.
