Class SAXEntityParser

java.lang.Object

org.netbeans.api.xml.parsers.SAXEntityParser

All Implemented Interfaces:

XMLReader

public class SAXEntityParser
extends Object
implements XMLReader

SAX parser wrapper allowing to parse parsed XML entities (including DTDs) for wellformedness.

Default implementation cannot be used for parsing of XML document entities! It wraps client's parser that it actually used for performing the parsing task.

Primary use case (parse general entity):

   XMLReader entityParser = new SAXEntityParser(xmlReader);
   entityParser.setErrorHandler(errorHandler);
   entityParser.parse(inputSource);
 

Secondary use case (delegating parser): It requires subclassing and allow subclass entirely define internal wrapping logic. Warning: Implementation gurantees only proper ErrorHandler callbacks.

Constructor Detail

SAXEntityParser

public SAXEntityParser(XMLReader peer)

Creates a new instance of general entity parser.

Parameters:

peer - parser that will be used for parsing. Wrapped parser is exclusively owned by this class no other clients can share it.

SAXEntityParser

public SAXEntityParser(XMLReader peer,
                       boolean generalEntity)

Creates a new instance of SAXEntityParser.

Parameters:

peer - parser that will be used for parsing

generalEntity - if false treat entity as parameter entity (i.e. DTD entities).

Method Detail

parse

public void parse(InputSource entity)
           throws IOException,
                  SAXException

Start entity parsing using peer parser. Staring from this moment all other methods calls are not supported.

Specified by:

parse in interface XMLReader

Parameters:

entity - entity input source

Throws:

IOException

SAXException

wrapInputSource

protected InputSource wrapInputSource(InputSource input)

Create wrapper input source. Default implementation utilizes fact that default EntityResolver redirects the first query to wrapped InputSource.

Parameters:

input - InputSource to be wrapped.

Returns:

InputSource that hosts of client's one

Since:

0.6

propagateException

protected boolean propagateException(SAXParseException ex)

Examine if the exception should be propagated into client's ErrorHandler.

Parameters:

ex - examined exception

Returns:

true if the exception originates from client's InputSource and should be propagated.
