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:

- Call the `reset` method on each component before parsing. This is only required if the configuration is re-using existing components that conform to the `XMLComponent` interface. If the configuration uses all custom parts, then it is free to implement everything as it sees fit as long as it follows the other guidelines.
- Call the `setFeature` and `setProperty` method on each component during parsing to propagate features and properties that have changed. This is only required if the configuration is re-using existing components that conform to the `XMLComponent` interface. If the configuration uses all custom parts, then it is free to implement everything as it sees fit as long as it follows the other guidelines.
- Pass the same unique String references for all symbols that are propagated to the registered handlers. Symbols include, but may not be limited to, the names of elements and attributes (including their uri, prefix, and localpart). This is suggested but not an absolute must. However, the standard parser components may require access to the same symbol table for creation of unique symbol references to be propagated in the XNI pipeline.

Method Detail

### parse

    public 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:
    `source` - 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

    public 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

    public 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

    public 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

    public 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

    public void setProperty(java.lang.String propertyId,

  Sets the value of a property. This method is called by the parser and gets propagated to components in this parser configuration.
  Parameters:
