getContentHandler
public ContentHandler getContentHandler()
Get the ContentHandler registered using setContentHandler()
getDTDHandler
public DTDHandler getDTDHandler()
Return the current DTD handler.
- Always null, since no DTD handler is used even if one has been
supplied.
getEntityResolver
public EntityResolver getEntityResolver()
Return the current entity resolver.
- Always null, since no entity resolver is used even if one
is supplied.
getErrorHandler
public ErrorHandler getErrorHandler()
Return the current error handler.
- The current error handler, or null if none
has been registered.
getFeature
public boolean getFeature(String name)
throws SAXNotRecognizedException,
SAXNotSupportedException
Look up the value of a feature.
The feature name is any fully-qualified URI. It is
possible for an XMLReader to recognize a feature name but
to be unable to return its value; this is especially true
in the case of an adapter for a SAX1 Parser, which has
no way of knowing whether the underlying parser is
performing validation or expanding external entities.
All XMLReaders are required to recognize the
http://xml.org/sax/features/namespaces and the
http://xml.org/sax/features/namespace-prefixes feature names.
name
- The feature name, which is a fully-qualified URI.
- The current state of the feature (true or false).
getParent
public XMLReader getParent()
Get the parent reader.
This method allows the application to query the parent
reader (which may be another filter). It is generally a
bad idea to perform any operations on the parent reader
directly: they should all pass through this filter.
- The parent filter, or null if none has been set.
getProperty
public Object getProperty(String name)
throws SAXNotRecognizedException,
SAXNotSupportedException
Look up the value of a property.
The property name is any fully-qualified URI. It is
possible for an XMLReader to recognize a property name but
to be unable to return its state; this is especially true
in the case of an adapter for a SAX1
Parser
.
XMLReaders are not required to recognize any specific
property names, though an initial core set is documented for
SAX2.
Some property values may be available only in specific
contexts, such as before, during, or after a parse.
Implementors are free (and encouraged) to invent their own properties,
using names built on their own URIs.
name
- The property name, which is a fully-qualified URI.
- The current value of the property.
parse
public void parse(InputSource input)
throws IOException,
SAXException
"Parse an XML document." In the context of a Transformer, this means
perform a transformation. The method is equivalent to transform().
parse
public void parse(String systemId)
throws IOException,
SAXException
Parse (i.e. transform) an XML document from a system identifier (URI).
This method is a shortcut for the common case of reading a
document from a system identifier. It is the exact
equivalent of the following:
parse(new InputSource(systemId));
If the system identifier is a URL, it must be fully resolved
by the application before it is passed to the parser.
systemId
- The system identifier (URI).
parse(org.xml.sax.InputSource)
setContentHandler
public void setContentHandler(ContentHandler handler)
Register a content handler to receive the output of the transformation
filter. If the content handler is also a LexicalHandler, and if no LexicalHandler
is separately registered, the ContentHandler will also act as the LexicalHandler
setDTDHandler
public void setDTDHandler(DTDHandler handler)
Allow an application to register a DTD event handler.
If the application does not register a DTD handler, all DTD
events reported by the SAX parser will be silently ignored.
Applications may register a new or different handler in the
middle of a parse, and the SAX parser must begin using the new
handler immediately.
handler
- The DTD handler.
setEntityResolver
public void setEntityResolver(EntityResolver resolver)
Allow an application to register an entity resolver.
If the application does not register an entity resolver,
the XMLReader will perform its own default resolution.
Applications may register a new or different resolver in the
middle of a parse, and the SAX parser must begin using the new
resolver immediately.
resolver
- The entity resolver.
setErrorHandler
public void setErrorHandler(ErrorHandler handler)
Allow an application to register an error event handler.
If the application does not register an error handler, all
error events reported by the SAX parser will be silently
ignored; however, normal processing may not continue. It is
highly recommended that all SAX applications implement an
error handler to avoid unexpected bugs.
Applications may register a new or different handler in the
middle of a parse, and the SAX parser must begin using the new
handler immediately.
handler
- The error handler.
setFeature
public void setFeature(String name,
boolean value)
throws SAXNotRecognizedException,
SAXNotSupportedException
Set the state of a feature.
The feature name is any fully-qualified URI. It is
possible for an XMLReader to recognize a feature name but
to be unable to set its value; this is especially true
in the case of an adapter for a SAX1
Parser
,
which has no way of affecting whether the underlying parser is
validating, for example.
All XMLReaders are required to support setting
http://xml.org/sax/features/namespaces to true and
http://xml.org/sax/features/namespace-prefixes to false.
Some feature values may be immutable or mutable only
in specific contexts, such as before, during, or after
a parse.
name
- The feature name, which is a fully-qualified URI.
setParent
public void setParent(XMLReader parent)
Set the parent reader.
This method allows the application to link the filter to
a parent reader (which may be another filter). The argument
may not be null.
parent
- The parent reader (the supplier of SAX events).
setProperty
public void setProperty(String name,
Object value)
throws SAXNotRecognizedException,
SAXNotSupportedException
Set the value of a property.
The property name is any fully-qualified URI. It is
possible for an XMLReader to recognize a property name but
to be unable to set its value; this is especially true
in the case of an adapter for a SAX1
Parser
.
XMLReaders are not required to recognize setting
any specific property names, though a core set is provided with
SAX2.
Some property values may be immutable or mutable only
in specific contexts, such as before, during, or after
a parse.
This method is also the standard mechanism for setting
extended handlers.
name
- The property name, which is a fully-qualified URI.
