A very basic parser configuration. This configuration class can be used as a base class for custom parser configurations. The basic parser configuration creates the symbol table (if not specified at construction time) and manages all of the recognized features and properties.

The basic parser configuration does not mandate any particular pipeline configuration or the use of specific components except for the symbol table. If even this is too much for a basic parser configuration, the programmer can create a new configuration class that implements the XMLParserConfiguration interface.

Subclasses of the basic parser configuration can add their own recognized features and properties by calling the addRecognizedFeature and addRecognizedProperty methods, respectively.

The basic parser configuration assumes that the configuration will be made up of various parser components that implement the XMLComponent interface. If subclasses of this configuration create their own components for use in the parser configuration, then each component should be added to the list of components by calling the addComponent method. The basic parser configuration will make sure to call the reset method of each registered component before parsing an instance document.

This class recognizes the following features and properties:

parseback to summary
public abstract void parse(XMLInputSource inputSource) throws XNIException, IOException

Redeclares com.sun.org.apache.xerces.internal.xni.parser.XMLParserConfiguration.parse.

Parse an XML document.

The parser can use this method to instruct this configuration to begin parsing an XML document from any valid input source (a character stream, a byte stream, or a URI).

Parsers may not invoke this method while a parse is in progress. Once a parse is complete, the parser may then parse another XML document.

This method is synchronous: it will not return until parsing has ended. If a client application wants to terminate parsing early, it should throw an exception.

Parameters
inputSource:XMLInputSource

The input source for the top-level of the XML document.

Exceptions
XNIException:
Any XNI exception, possibly wrapping another exception.
IOException:
An IO exception from the parser, possibly from a byte stream or character stream supplied by the parser.
resetback to summary
protected void reset() throws XNIException

reset all components before parsing and namespace context

setDocumentHandlerback to summary
public void setDocumentHandler(XMLDocumentHandler documentHandler)

Implements com.sun.org.apache.xerces.internal.xni.parser.XMLParserConfiguration.setDocumentHandler.

Sets the document handler on the last component in the pipeline to receive information about the document.

Parameters
documentHandler:XMLDocumentHandler

The document handler.

setDTDContentModelHandlerback to summary
public void setDTDContentModelHandler(XMLDTDContentModelHandler handler)

Implements com.sun.org.apache.xerces.internal.xni.parser.XMLParserConfiguration.setDTDContentModelHandler.

Sets the DTD content model handler.

Parameters
handler:XMLDTDContentModelHandler

The DTD content model handler.

setDTDHandlerback to summary
public void setDTDHandler(XMLDTDHandler dtdHandler)

Implements com.sun.org.apache.xerces.internal.xni.parser.XMLParserConfiguration.setDTDHandler.

Sets the DTD handler.

Parameters
dtdHandler:XMLDTDHandler

The DTD handler.

setEntityResolverback to summary
public void setEntityResolver(XMLEntityResolver resolver)

Implements com.sun.org.apache.xerces.internal.xni.parser.XMLParserConfiguration.setEntityResolver.

Sets the resolver used to resolve external entities. The EntityResolver interface supports resolution of public and system identifiers.

Parameters
resolver:XMLEntityResolver

The new entity resolver. Passing a null value will uninstall the currently installed resolver.

setErrorHandlerback to summary
public void setErrorHandler(XMLErrorHandler errorHandler)

Implements com.sun.org.apache.xerces.internal.xni.parser.XMLParserConfiguration.setErrorHandler.

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.

Parameters
errorHandler:XMLErrorHandler

The error handler.

Exceptions
NullPointerException:
If the handler argument is null.

setFeatureback to summary
public void setFeature(String featureId, boolean state) throws XMLConfigurationException

Implements com.sun.org.apache.xerces.internal.xni.parser.XMLParserConfiguration.setFeature.

Set the state of a feature. Set the state of any feature in a SAX2 parser. The parser might not recognize the feature, and if it does recognize it, it might not be able to fulfill the request.

Parameters
featureId:String

The unique identifier (URI) of the feature.

state:boolean

The requested state of the feature (true or false).

Exceptions
XMLConfigurationException:
If the requested feature is not known.
setLocaleback to summary
public void setLocale(Locale locale) throws XNIException

Implements com.sun.org.apache.xerces.internal.xni.parser.XMLParserConfiguration.setLocale.

Set the locale to use for messages.

Parameters
locale:Locale

The locale object to use for localization of messages.

Exceptions

Thrown if the parser does not support the specified locale.
