javax.xml.parsers
Class SAXParserFactory

java.lang.Object
javax.xml.parsers.SAXParserFactory

Direct Known Subclasses:

JXSAXParserFactory

public abstract class SAXParserFactory

extends java.lang.Object

Defines a factory API that enables applications to configure and obtain a SAX based parser to parse XML documents.

Since:

JAXP 1.0

Constructor Summary

SAXParserFactory()

Method Summary

abstract boolean	getFeature(java.lang.String name) returns the particular property requested for in the underlying implementation of org.xml.sax.XMLReader.
boolean	isNamespaceAware() Indicates whether or not the factory is configured to produce parsers which are namespace aware.
boolean	isValidating() Indicates whether or not the factory is configured to produce parsers which validate the XML content during parse.
static SAXParserFactory	newInstance() Obtain a new instance of a SAXParserFactory.
abstract SAXParser	newSAXParser() Creates a new instance of a SAXParser using the currently configured factory parameters.
abstract void	setFeature(java.lang.String name, boolean value) Sets the particular feature in the underlying implementation of org.xml.sax.XMLReader.
void	setNamespaceAware(boolean awareness) Specifies that the parser produced by this code will provide support for XML namespaces.
void	setValidating(boolean validating) Specifies that the parser produced by this code will validate documents as they are parsed.

Method Detail

newInstance

public static SAXParserFactory newInstance()

Obtain a new instance of a SAXParserFactory. This static method creates a new factory instance This method uses the following ordered lookup procedure to determine the SAXParserFactory implementation class to load:

• Use the javax.xml.parsers.SAXParserFactory system property.
• Use the JAVA_HOME(the parent directory where jdk is installed)/lib/jaxp.properties for a property file that contains the name of the implementation class keyed on the same value as the system property defined above.
• Use the Services API (as detailed in teh JAR specification), if available, to determine the classname. The Services API will look for a classname in the file META-INF/services/javax.xml.parsers.SAXParserFactory in jars available to the runtime.
• Platform default SAXParserFactory instance.

Once an application has obtained a reference to a SAXParserFactory it can use the factory to configure and obtain parser instances.

Throws:

FactoryConfigurationError - if the implementation is not available or cannot be instantiated.

newSAXParser

public abstract SAXParser newSAXParser()
                                throws ParserConfigurationException,
                                       SAXException

Creates a new instance of a SAXParser using the currently configured factory parameters.

Throws:

ParserConfigurationException - if a parser cannot be created which satisfies the requested configuration.

SAXException

setNamespaceAware

public void setNamespaceAware(boolean awareness)

Specifies that the parser produced by this code will provide support for XML namespaces. By default the value of this is set to false

setValidating

public void setValidating(boolean validating)

Specifies that the parser produced by this code will validate documents as they are parsed. By default the value of this is set to false

isNamespaceAware

public boolean isNamespaceAware()

Indicates whether or not the factory is configured to produce parsers which are namespace aware.

isValidating

public boolean isValidating()

Indicates whether or not the factory is configured to produce parsers which validate the XML content during parse.

setFeature

public abstract void setFeature(java.lang.String name,
                                boolean value)
                         throws ParserConfigurationException,
                                SAXNotRecognizedException,
                                SAXNotSupportedException

Sets the particular feature in the underlying implementation of org.xml.sax.XMLReader. A list of the core features and properties can be found at http://www.megginson.com/SAX/Java/features.html

Parameters:

name - The name of the feature to be set.

value - The value of the feature to be set.

Throws:

SAXNotRecognizedException - When the underlying XMLReader does not recognize the property name.

SAXNotSupportedException - When the underlying XMLReader recognizes the property name but doesn't support the property.

ParserConfigurationException

getFeature

public abstract boolean getFeature(java.lang.String name)
                            throws ParserConfigurationException,
                                   SAXNotRecognizedException,
                                   SAXNotSupportedException

returns the particular property requested for in the underlying implementation of org.xml.sax.XMLReader.

Parameters:

name - The name of the property to be retrieved.

Returns:

Value of the requested property.

Throws:

SAXNotRecognizedException - When the underlying XMLReader does not recognize the property name.

SAXNotSupportedException - When the underlying XMLReader recognizes the property name but doesn't support the property.
