Interface XMLParserConfiguration

All Superinterfaces:
XMLComponentManager
All Known Subinterfaces:
XMLPullParserConfiguration

public interface XMLParserConfiguration
extends XMLComponentManager

Represents a parser configuration. The parser configuration maintains a table of recognized features and properties, assembles components for the parsing pipeline, and is responsible for initiating parsing of an XML document.

By separating the configuration of a parser from the specific parser instance, applications can create new configurations and re-use the existing parser components and external API generators (e.g. the DOMParser and SAXParser).

The internals of any specific parser configuration instance are hidden. Therefore, each configuration may implement the parsing mechanism any way necessary. However, the parser configuration should follow these guidelines:

Method Detail

parse

void parse(XMLInputSource inputSource)
           throws XNIException,
                  java.io.IOException
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.

When this method returns, all characters streams and byte streams opened by the parser are closed.

Parameters:
inputSource - The input source for the top-level of the XML document.
Throws:
XNIException - Any XNI exception, possibly wrapping another exception.
java.io.IOException - An IO exception from the parser, possibly from a byte stream or character stream supplied by the parser.

addRecognizedFeatures

void addRecognizedFeatures(java.lang.String[] featureIds)
Allows a parser to add parser specific features to be recognized and managed by the parser configuration.

Parameters:
featureIds - An array of the additional feature identifiers to be recognized.

setFeature

void setFeature(java.lang.String featureId,
                boolean state)
                throws XMLConfigurationException
Sets the state of a feature. This method is called by the parser and gets propagated to components in this parser configuration.

Parameters:
featureId - The feature identifier.
state - The state of the feature.
Throws:
XMLConfigurationException - Thrown if there is a configuration error.

getFeature

boolean getFeature(java.lang.String featureId)
                   throws XMLConfigurationException
Returns the state of a feature.

Specified by:
getFeature in interface XMLComponentManager
Parameters:
featureId - The feature identifier.
Throws:
XMLConfigurationException - Thrown if there is a configuration error.

addRecognizedProperties

void addRecognizedProperties(java.lang.String[] propertyIds)
Allows a parser to add parser specific properties to be recognized and managed by the parser configuration.

Parameters:
propertyIds - An array of the additional property identifiers to be recognized.

setProperty

void setProperty(java.lang.String propertyId,
                 java.lang.Object value)
                 throws XMLConfigurationException
Sets the value of a property. This method is called by the parser and gets propagated to components in this parser configuration.

Parameters:
propertyId - The property identifier.
value - The value of the property.
Throws:
XMLConfigurationException - Thrown if there is a configuration error.

getProperty

java.lang.Object getProperty(java.lang.String propertyId)
                             throws XMLConfigurationException
Returns the value of a property.

Specified by:
getProperty in interface XMLComponentManager
Parameters:
propertyId - The property identifier.
Throws:
XMLConfigurationException - Thrown if there is a configuration error.

setErrorHandler

void setErrorHandler(XMLErrorHandler errorHandler)
Sets the error handler.

Parameters:
errorHandler - The error resolver.

getErrorHandler

XMLErrorHandler getErrorHandler()
Returns the registered error handler.


setDocumentHandler

void setDocumentHandler(XMLDocumentHandler documentHandler)
Sets the document handler to receive information about the document.

Parameters:
documentHandler - The document handler.

getDocumentHandler

XMLDocumentHandler getDocumentHandler()
Returns the registered document handler.


setDTDHandler

void setDTDHandler(XMLDTDHandler dtdHandler)
Sets the DTD handler.

Parameters:
dtdHandler - The DTD handler.

getDTDHandler

XMLDTDHandler getDTDHandler()
Returns the registered DTD handler.


setDTDContentModelHandler

void setDTDContentModelHandler(XMLDTDContentModelHandler dtdContentModelHandler)
Sets the DTD content model handler.

Parameters:

Returns the registered DTD content model handler.


setEntityResolver

void setEntityResolver(XMLEntityResolver entityResolver)
Sets the entity resolver.

Parameters:
entityResolver - The new entity resolver.

getEntityResolver

XMLEntityResolver getEntityResolver()
Returns the registered entity resolver.


setLocale

void setLocale(java.util.Locale locale)
               throws XNIException
Set the locale to use for messages.

Parameters:
