public class ParserConfigurationSettings
extends Object
implements XMLComponentManager

This class implements the basic operations for managing parser configuration features and properties. This utility class can be used as a base class for parser configurations or separately to encapsulate a number of parser settings as a component manager.

This class can be constructed with a "parent" settings object (in the form of an XMLComponentManager) that allows parser configuration settings to be "chained" together.

Method Detail

addRecognizedFeatures

public void addRecognizedFeatures(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

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

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 - The unique identifier (URI) of the feature.

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

Throws:

XMLConfigurationException - If the requested feature is not known.

addRecognizedProperties

public void addRecognizedProperties(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

public void setProperty(String propertyId,
                        Object value)
                 throws XMLConfigurationException

setProperty

Parameters:

propertyId -

value -

Throws:

XMLConfigurationException - If the requested feature is not known.

getFeature

public boolean getFeature(String featureId)
                   throws XMLConfigurationException

Returns the state of a feature.

Specified by:

getFeature in interface XMLComponentManager

Parameters:

featureId - The feature identifier.

Returns:

true if the feature is supported

Throws:

XMLConfigurationException - Thrown for configuration error. In general, components should only throw this exception if it is really a critical error.

getProperty

public Object getProperty(String propertyId)
                   throws XMLConfigurationException

Returns the value of a property.

Specified by:

getProperty in interface XMLComponentManager

Parameters:

propertyId - The property identifier.

Returns:

the value of the property

Throws:

XMLConfigurationException - Thrown for configuration error. In general, components should only throw this exception if it is really a critical error.

checkFeature

protected void checkFeature(String featureId)
                     throws XMLConfigurationException

Check a feature. If feature is known and supported, this method simply returns. Otherwise, the appropriate exception is thrown.

Parameters:

featureId - The unique identifier (URI) of the feature.

Throws:

XMLConfigurationException - If the requested feature is not known.

checkProperty

protected void checkProperty(String propertyId)
                      throws XMLConfigurationException

Check a property. If the property is known and supported, this method simply returns. Otherwise, the appropriate exception is thrown.

Parameters:

propertyId - The unique identifier (URI) of the property being set.

Throws:

XMLConfigurationException - If the requested feature is not known.
