public abstract class SAXParser extends Object
XMLReader
implementation class. In JAXP 1.0, this class wrapped the
Parser
interface, however this interface was
replaced by the XMLReader
. For ease
of transition, this class continues to support the same name
and interface as well as supporting new methods.
An instance of this class can be obtained from the
SAXParserFactory.newSAXParser()
method.
Once an instance of this class is obtained, XML can be parsed from
a variety of input sources. These input sources are InputStreams,
Files, URLs, and SAX InputSources.This static method creates a new factory instance based on a system property setting or uses the platform default if no property has been defined.
The system property that controls which Factory implementation
to create is named "javax.xml.parsers.SAXParserFactory"
.
This property names a class that is a concrete subclass of this
abstract class. If no property is defined, a platform default
will be used.
HandlerBase
or the
DefaultHandler
are called.
Implementors of this class which wrap an underlaying implementation
can consider using the ParserAdapter
class to initially adapt their SAX1 implementation to work under
this revised class.

specified
DefaultHandler . |
void |
parse(File f,
HandlerBase hb)
Parse the content of the file specified as XML using the
specified
HandlerBase . |
void |
parse(InputSource is,
DefaultHandler dh)
Parse the content given
InputSource
as XML using the specified
DefaultHandler . |
void |
parse(InputSource is,
HandlerBase hb)
Parse the content given
InputSource
as XML using the specified
HandlerBase . |
void |
parse(InputStream is,
DefaultHandler dh)
Parse the content of the given
InputStream
instance as XML using the specified
DefaultHandler . |
void |
parse(InputStream is,
DefaultHandler dh,
String systemId)
Parse the content of the given
InputStream
instance as XML using the specified
DefaultHandler . |
void |
parse(InputStream is,
HandlerBase hb)
Parse the content of the given
InputStream
instance as XML using the specified HandlerBase . |
void |
parse(InputStream is,
HandlerBase hb,
String systemId)
Parse the content of the given
InputStream
instance as XML using the specified HandlerBase . |
void |
parse(String uri,
DefaultHandler dh)
Parse the content described by the giving Uniform Resource
Identifier (URI) as XML using the specified
DefaultHandler . |
void |
parse(String uri,
HandlerBase hb)
Parse the content described by the giving Uniform Resource
Identifier (URI) as XML using the specified
HandlerBase . |
void |
reset()
Reset this
SAXParser to its original configuration. |
abstract void |
setProperty(String name,
Object value)
Sets the particular property in the underlying implementation of
XMLReader . |
protected SAXParser()
Protected constructor to prevent instaniation.
Use SAXParserFactory.newSAXParser()
.
public void reset()
Reset this SAXParser
to its original configuration.
SAXParser
is reset to the same state as when it was created with
SAXParserFactory.newSAXParser()
.
reset()
is designed to allow the reuse of existing SAXParser
s
thus saving resources associated with the creation of new SAXParser
s.
The reset SAXParser
is not guaranteed to have the same Schema
Object
, e.g. Object.equals(Object obj)
. It is guaranteed to have a functionally equal
Schema
.
