Class XMLEntityManager

java.lang.Object
  extended by org.apache.xerces.impl.XMLEntityManager
All Implemented Interfaces:
org.apache.xerces.xni.parser.XMLComponent, org.apache.xerces.xni.parser.XMLEntityResolver

public class XMLEntityManager
extends java.lang.Object
implements org.apache.xerces.xni.parser.XMLComponent, org.apache.xerces.xni.parser.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:

Constructor Detail

XMLEntityManager

public XMLEntityManager()
Default constructor.


XMLEntityManager

public XMLEntityManager(XMLEntityManager entityManager)
Constructs an entity manager that shares the specified entity declarations during each parse.

Parameters:
standalone - True if document entity is standalone.

isStandalone

public boolean isStandalone()
Returns true if the document entity is standalone.

Adds an internal entity declaration.

Note: This method ignores subsequent entity declarations.

Note: The name should be a unique symbol. The SymbolTable can be used for this purpose.

Parameters:
name - The name of the entity.
text - The text of the entity.
See Also:

                       throws java.io.IOException
Adds an external entity declaration.

Note: This method ignores subsequent entity declarations.

Note: The name should be a unique symbol. The SymbolTable can be used for this purpose.

Parameters:
name - The name of the entity.
publicId - The public identifier of the entity.
literalSystemId - The system identifier of the entity.
baseSystemId - The base system identifier of the entity. This is the system identifier of the entity where the entity being added and is used to expand the system identifier when the system identifier is a relative URI. When null the system identifier of the first external entity on the stack is used instead.

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

getFeatureDefault

public java.lang.Boolean getFeatureDefault(java.lang.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 org.apache.xerces.xni.parser.XMLComponent
Parameters:
featureId - The feature identifier.
Since:
Xerces 2.2.0

getPropertyDefault

public java.lang.Object getPropertyDefault(java.lang.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 org.apache.xerces.xni.parser.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 java.lang.String expandSystemId(java.lang.String systemId,
                                              java.lang.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 java.io.OutputStream createOutputStream(java.lang.String uri)
                                               throws java.io.IOException
Throws:
java.io.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 java.io.Reader createReader(java.io.InputStream inputStream,
                                      java.lang.String encoding,
                                      java.lang.Boolean isBigEndian)
                               throws java.io.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:
java.io.IOException

fixURI

protected static java.lang.String fixURI(java.lang.String str)
Fixes a platform dependent filename to standard URI form.

Parameters:
str - The string to fix.
Returns:
Returns the fixed URI string.
