SAXParser
public
abstract
class
SAXParser
extends Object
java.lang.Object | |
↳ | javax.xml.parsers.SAXParser |
Defines the API that wraps an 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.
Implementations of this class which wrap an underlying implementation
can consider using the ParserAdapter
class to initially adapt their SAX1 implementation to work under
this revised class.

reset
public void reset ()
Reset this SAXParser
to its original configuration.

is reset to the same state as when it was created with

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
.
setProperty
public abstract void setProperty (String name, Object value)
Sets the particular property in the underlying implementation of
XMLReader
.
A list of the core features and properties can be found at
http://sax.sourceforge.net/?selected=get-set.
Parameters | |
---|---|
name |
String : The name of the property to be set. |
value |
Object : The value of the property 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. |
