XMLEntityManager (Xerces2 Java 2.11.1 API)

java.lang.Object
- org.apache.xerces.impl.XMLEntityManager

All Implemented Interfaces:

XMLComponent, XMLEntityResolver
```
public class XMLEntityManager
extends Object
implements XMLComponent, XMLEntityResolver
```
The entity manager handles the registration of general and parameter entities; resolves entities; and starts entities. The entity manager is a central component in a standard parser configuration and this class works directly with the entity scanner to manage the underlying xni.
This component requires the following features and properties from the component manager that uses it:
- http://xml.org/sax/features/validation
- http://xml.org/sax/features/external-general-entities
- http://xml.org/sax/features/external-parameter-entities
- http://apache.org/xml/features/allow-java-encodings
- http://apache.org/xml/properties/internal/symbol-table
- http://apache.org/xml/properties/internal/error-reporter
- http://apache.org/xml/properties/internal/entity-resolver

    reset in interface XMLComponent
    
    Parameters:
    componentManager - The component manager.
    
    Throws:
    
    SAXException - Thrown by component on initialization error. For example, if a feature or property is required for the operation of the component, the component manager may throw a SAXNotRecognizedException or a SAXNotSupportedException.
    
    XMLConfigurationException
  - reset
```
public void reset()
```
  - getRecognizedFeatures
```
public 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.
    
    Specified by:
    
    getRecognizedFeatures in interface XMLComponent
  - setFeature
```
public void setFeature(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.
    
    Specified by:
    
    setFeature in interface XMLComponent
    
    Parameters:
    featureId - The feature identifier.
    state - The state of the feature.
    
    Throws:
    
    SAXNotRecognizedException - The component should not throw this exception.
    
    SAXNotSupportedException - The component should not throw this exception.
    
    XMLConfigurationException - Thrown for configuration error. In general, components should only throw this exception if it is really a critical error.
  - getRecognizedProperties
```
public 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.
    
    Specified by:
    
    getRecognizedProperties in interface XMLComponent
  - setProperty
```
public void setProperty(String propertyId,
               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.
    
    Specified by:
    
    setProperty in interface XMLComponent
    
    Parameters:
    propertyId - The property identifier.
    value - The value of the property.
    
    Throws:
    
    SAXNotRecognizedException - The component should not throw this exception.
    
    SAXNotSupportedException - The component should not throw this exception.
    
    XMLConfigurationException - Thrown for configuration error. In general, components should only throw this exception if it is really a critical error.
  - getFeatureDefault
```
public Boolean getFeatureDefault(String featureId)
```
    Returns the default state for a feature, or null if this component does not want to report a default value for this feature.
    
    Specified by:
    
    getFeatureDefault in interface XMLComponent
    
    Parameters:
    featureId - The feature identifier.
    Since:
    
    Xerces 2.2.0
  - getPropertyDefault
```
public Object getPropertyDefault(String propertyId)
```
    Returns the default state for a property, or null if this component does not want to report a default value for this property.
    
    Specified by:
    
    getPropertyDefault in interface XMLComponent
    
    Parameters:
    propertyId - The property identifier.
    Since:
    
    Xerces 2.2.0
  - absolutizeAgainstUserDir
```
public static void absolutizeAgainstUserDir(URI uri)
                                     throws URI.MalformedURIException
```
    Absolutizes a URI using the current value of the "user.dir" property as the base URI. If the URI is already absolute, this is a no-op.
    
    Parameters:
    uri - the URI to absolutize
    
    Throws:
    
    URI.MalformedURIException
  - expandSystemId
```
public static String expandSystemId(String systemId,
                    String baseSystemId,
                    boolean strict)
                             throws URI.MalformedURIException
```
    Expands a system id and returns the system id as a URI, if it can be expanded. A return value of null means that the identifier is already expanded. An exception thrown indicates a failure to expand the id.
    
    Parameters:
    systemId - The systemId to be expanded.
    
    Returns:
    Returns the URI string representing the expanded system identifier. A null value indicates that the given system identifier is already expanded.
    
    Throws:
    
    URI.MalformedURIException
  - createOutputStream
```
public static OutputStream createOutputStream(String uri)
                                       throws IOException
```
    Throws:
    
    IOException
  - getEncodingInfo
```
protected org.apache.xerces.impl.XMLEntityManager.EncodingInfo getEncodingInfo(byte[] b4,
                                                                   int count)
```
    Returns the IANA encoding name that is auto-detected from the bytes specified, with the endian-ness of that encoding where appropriate.
    
    Parameters:
    b4 - The first four bytes of the input.
    count - The number of bytes actually read.
    
    Returns:
    an instance of EncodingInfo which represents the auto-detected encoding.
  - createReader
```
protected Reader createReader(InputStream inputStream,
                  String encoding,
                  Boolean isBigEndian)
                       throws IOException
```
    Creates a reader capable of reading the given input stream in the specified encoding.
    
    Parameters:
    inputStream - The input stream.
    encoding - The encoding name that the input stream is encoded using. If the user has specified that Java encoding names are allowed, then the encoding name may be a Java encoding name; otherwise, it is an ianaEncoding name.
    isBigEndian - For encodings (like uCS-4), whose names cannot specify a byte order, this tells whether the order is bigEndian. Null means unknown or not relevant.
    
    Returns:
    Returns a reader.
    
    Throws:
    
    IOException
  - fixURI
```
protected static String fixURI(String str)
```
    Fixes a platform dependent filename to standard URI form.
    
    Parameters:
    str - The string to fix.
    
    Returns:
    Returns the fixed URI string.
