public interface XMLComponent

The component interface defines methods that must be implemented by components in a parser configuration. The component methods allow the component manager to initialize the component state and notify the component when feature and property values change.

XMLComponentManager

Method Summary

java.lang.String[]	getRecognizedFeatures() Returns a list of feature identifiers that are recognized by this component.
java.lang.String[]	getRecognizedProperties() Returns a list of property identifiers that are recognized by this component.
void	reset(XMLComponentManager componentManager) Resets the component.
void	setFeature(java.lang.String featureId, boolean state) Sets the state of a feature.
void	setProperty(java.lang.String propertyId, java.lang.Object value) Sets the value of a property.

Method Detail

reset

public void reset(XMLComponentManager componentManager)
           throws XMLConfigurationException

Resets the component. The component can query the component manager about any features and properties that affect the operation of the component.

Parameters:

componentManager - The component manager.

Throws:

XNIException - Thrown by component on initialization error.

getRecognizedFeatures

public java.lang.String[] getRecognizedFeatures()

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

setFeature

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

Sets the state of a feature. This method is called by the component manager any time after reset when a feature changes state.

Note: Components should silently ignore features that do not affect the operation of the component.

Parameters:

featureId - The feature identifier.

state - The state of the feature.

Throws:

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

getRecognizedProperties

public java.lang.String[] getRecognizedProperties()

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

setProperty

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

Sets the value of a property. This method is called by the component manager any time after reset when a property changes value.

Note: Components should silently ignore properties that do not affect the operation of the component.

Parameters:

propertyId - The property identifier.

value - 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.
