Class XmlConfigurationParser

java.lang.Object

org.jboss.cache.config.parsing.XmlParserBase

org.jboss.cache.config.parsing.XmlConfigurationParser

public class XmlConfigurationParser
extends XmlParserBase

Reads in XMLconfiguration files and spits out a Configuration object. By default this class uses a validating parser (configurable).

Following system properties can be used for customizing parser behavior:

• -Djbosscache.config.validate=false will make the parser non-validating
• -Djbosscache.config.schemaLocation=url allows one to specify a validation schema that would override the one specified in the the xml document

This class is stateful and one instance should be used for parsing a single configuration file.

Since:

3.0

Constructor and Description
XmlConfigurationParser() Constructs a parser having validation enabled with a ErrorHandler that only logs the parser errors.
XmlConfigurationParser(boolean validating, ErrorHandler errorHandler) Same as XmlConfigurationParser(org.xml.sax.ErrorHandler).
XmlConfigurationParser(ErrorHandler errorHandler) If validation is on (default) one can specify an error handler for handling validation errors.

Methods

Modifier and Type	Method and Description
boolean	isValidating()
boolean	isValidElementRoot(Element element) Tests whether the element passed in is a modern (3.0) config element rather than a legacy one.
Configuration	parseElement(Element root) Root should be the jbosscache element in the configuration file.
Configuration	parseElementIgnoringRoot(Element root)
Configuration	parseFile(String filename) Parses an XML file and returns a new configuration.
Configuration	parseStream(InputStream configStream) Similar to parseFile(String), just that it does not create the input stream.

Constructor Detail

XmlConfigurationParser

public XmlConfigurationParser(ErrorHandler errorHandler)

If validation is on (default) one can specify an error handler for handling validation errors. The default error handler just logs parsing errors received.

XmlConfigurationParser

public XmlConfigurationParser(boolean validating,
                      ErrorHandler errorHandler)

Same as XmlConfigurationParser(org.xml.sax.ErrorHandler).

Parameters:

validating - should the underlaying parser disable the validation?

XmlConfigurationParser

public XmlConfigurationParser()

Constructs a parser having validation enabled with a ErrorHandler that only logs the parser errors.

Method Detail

parseFile

public Configuration parseFile(String filename)

Parses an XML file and returns a new configuration. For looking up the file, FileLookup is used.

See Also:

FileLookup

parseStream

public Configuration parseStream(InputStream configStream)

Similar to parseFile(String), just that it does not create the input stream.

parseElement

public Configuration parseElement(Element root)

Root should be the jbosscache element in the configuration file.

parseElementIgnoringRoot

public Configuration parseElementIgnoringRoot(Element root)

isValidating

public boolean isValidating()

isValidElementRoot

public boolean isValidElementRoot(Element element)

Tests whether the element passed in is a modern (3.0) config element rather than a legacy one.

Parameters:

element - element to test

Returns:

true of the element is a modern one and can be parsed using the current parser.
