Interface XMLGrammarLoader

All Known Implementing Classes:

XML11DTDProcessor, XMLDTDLoader, XMLSchemaLoader

public interface XMLGrammarLoader

The intention of this interface is to provide a generic means by which Grammar objects may be created without parsing instance documents. Implementations of this interface will know how to load specific types of grammars (e.g., DTD's or schemas); a wrapper will be provided for user applications to interact with these implementations.

Method Detail

getRecognizedFeatures

java.lang.String[] getRecognizedFeatures()

Returns a list of feature identifiers that are recognized by this XMLGrammarLoader. This method may return null if no features are recognized.

getFeature

boolean getFeature(java.lang.String featureId)
                   throws XMLConfigurationException

Returns the state of a feature.

Parameters:

featureId - The feature identifier.

Throws:

XMLConfigurationException - Thrown on configuration error.

setFeature

void setFeature(java.lang.String featureId,
                boolean state)
                throws XMLConfigurationException

Sets the state of a feature.

Parameters:

featureId - The feature identifier.

state - The state of the feature.

Throws:

XMLConfigurationException - Thrown when a feature is not recognized or cannot be set.

getRecognizedProperties

java.lang.String[] getRecognizedProperties()

Returns a list of property identifiers that are recognized by this XMLGrammarLoader. This method may return null if no properties are recognized.

getProperty

java.lang.Object getProperty(java.lang.String propertyId)
                             throws XMLConfigurationException

Returns the state of a property.

Parameters:

propertyId - The property identifier.

Throws:

XMLConfigurationException - Thrown on configuration error.

setProperty

void setProperty(java.lang.String propertyId,
                 java.lang.Object state)
                 throws XMLConfigurationException

Sets the state of a property.

Parameters:

propertyId - The property identifier.

state - The state of the property.

Throws:

XMLConfigurationException - Thrown when a property is not recognized or cannot be set.

setLocale

void setLocale(java.util.Locale locale)

Set the locale to use for messages.

Parameters:

locale - The locale object to use for localization of messages.

Throws:

XNIException - Thrown if the parser does not support the specified locale.

getLocale

java.util.Locale getLocale()

Return the Locale the XMLGrammarLoader is using.

setErrorHandler

void setErrorHandler(XMLErrorHandler errorHandler)

Sets the error handler.

Parameters:

errorHandler - The error handler.

getErrorHandler

XMLErrorHandler getErrorHandler()

Returns the registered error handler.

setEntityResolver

void setEntityResolver(XMLEntityResolver entityResolver)

Sets the entity resolver.

Parameters:

entityResolver - The new entity resolver.

getEntityResolver

XMLEntityResolver getEntityResolver()

Returns the registered entity resolver.

loadGrammar

Grammar loadGrammar(XMLInputSource source)
                    throws java.io.IOException,
                           XNIException

Returns a Grammar object by parsing the contents of the entity pointed to by source.

Parameters:

source - the location of the entity which forms the starting point of the grammar to be constructed.

Throws:

java.io.IOException - When a problem is encountered reading the entity XNIException When a condition arises (such as a FatalError) that requires parsing of the entity be terminated.
