Interface UnmarshallingContext

All Superinterfaces:

javax.xml.namespace.NamespaceContext

All Known Implementing Classes:

SAXUnmarshallerHandlerImpl

public interface UnmarshallingContext
extends javax.xml.namespace.NamespaceContext

Methods exposed by the unmarshalling coordinator object to the generated code. This interface will be implemented by the coordinator, which converts whatever events (e.g., SAX) into unmarshalling events.

Errors detected by the AbstractUnmarshallingEventHandlerImpl-derived classes should be either thrown as UnrepotedException or reported through the handleEvent method of this interface.

Method Detail

getGrammarInfo

GrammarInfo getGrammarInfo()

Obtains a reference to the current grammar info.

pushContentHandler

void pushContentHandler(UnmarshallingEventHandler handler,
                        int memento)

Pushes the current content handler into the stack and registers the newly specified content handler so that it can receive SAX events.

Parameters:

memento - When this newly specified handler will be removed from the stack, the leaveChild event will be fired to the parent handler with this memento.

popContentHandler

void popContentHandler()
                       throws org.xml.sax.SAXException

Pops a content handler from the stack and registers it as the current content handler.

This method will also fire the leaveChild event with the associated memento.

Throws:

org.xml.sax.SAXException

getCurrentHandler

UnmarshallingEventHandler getCurrentHandler()

Gets the current handler.

getNewlyDeclaredPrefixes

java.lang.String[] getNewlyDeclaredPrefixes()

Returns a list of prefixes newly declared on this element. This method has to be called after the pushAttributes(org.xml.sax.Attributes, boolean) method is called.

Returns:

A possible zero-length array of prefixes. The default prefix is represented by the empty string.

getAllDeclaredPrefixes

java.lang.String[] getAllDeclaredPrefixes()

Returns a list of all in-scope prefixes.

Returns:

A possible zero-length array of prefixes. The default prefix is represented by the empty string.

pushAttributes

void pushAttributes(org.xml.sax.Attributes atts,
                    boolean collectText)

Stores a new attribute set. This method should be called by the generated code when it "eats" an enterElement event.

Parameters:

collectText - false if the context doesn't need to fire text events for texts inside this element. True otherwise.

popAttributes

void popAttributes()

Discards the previously stored attribute set. This method should be called by the generated code when it "eats" a leaveElement event.

getAttribute

int getAttribute(java.lang.String uri,
                 java.lang.String name)

Gets the index of the attribute with the specified name. This is usually faster when you only need to test with a simple name.

Returns:

-1 if not found.

getUnconsumedAttributes

org.xml.sax.Attributes getUnconsumedAttributes()

Gets all the unconsumed attributes. If you need to find attributes based on more complex filter, you need to use this method.

consumeAttribute

void consumeAttribute(int idx)
                      throws org.xml.sax.SAXException

Fires an attribute event for the specified attribute, and marks the attribute as "used".

Throws:

org.xml.sax.SAXException

eatAttribute

java.lang.String eatAttribute(int idx)
                              throws org.xml.sax.SAXException

Marks the attribute as "used" and return the value of the attribute.

Throws:

org.xml.sax.SAXException

addPatcher

void addPatcher(java.lang.Runnable job)

Adds a job that will be executed at the last of the unmarshalling. This method is used to support ID/IDREF feature, but it can be used for other purposes as well.

Parameters:

job - The run method of this object is called.

addToIdTable

java.lang.String addToIdTable(java.lang.String id)

Adds the object which is currently being unmarshalled to the ID table.

Returns:

Returns the value passed as the parameter. This is a hack, but this makes it easier for ID transducer to do its job.

getObjectFromId

java.lang.Object getObjectFromId(java.lang.String id)

Looks up the ID table and gets associated object.

Returns:

If there is no object associated with the given id, this method returns null.

getLocator

org.xml.sax.Locator getLocator()

Gets the current source location information.

handleEvent

void handleEvent(javax.xml.bind.ValidationEvent event,
                 boolean canRecover)
                 throws org.xml.sax.SAXException

Reports an error to the user, and asks if s/he wants to recover. If the canRecover flag is false, regardless of the client instruction, an exception will be thrown. Only if the flag is true and the user wants to recover from an error, the method returns normally. The thrown exception will be catched by the unmarshaller.

Throws:

org.xml.sax.SAXException

resolveNamespacePrefix

java.lang.String resolveNamespacePrefix(java.lang.String prefix)

getBaseUri

java.lang.String getBaseUri()

isUnparsedEntity

boolean isUnparsedEntity(java.lang.String entityName)

isNotation

boolean isNotation(java.lang.String notationName)

getTracer

com.sun.xml.bind.unmarshaller.Tracer getTracer()

Gets a tracer object. Tracer can be used to trace the unmarshalling behavior. Note that to debug the unmarshalling process, you have to configure XJC so that it will emit trace codes in the unmarshaller.
