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

public void pushAttributes(Attributes atts,
                           boolean collectTextFlag)

Description copied from interface: UnmarshallingContext

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

Specified by:

pushAttributes in interface UnmarshallingContext

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

popAttributes

public void popAttributes()

Description copied from interface: UnmarshallingContext

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

Specified by:

popAttributes in interface UnmarshallingContext

getUnconsumedAttributes

public Attributes getUnconsumedAttributes()

Description copied from interface: UnmarshallingContext

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

Specified by:

getUnconsumedAttributes in interface UnmarshallingContext

getAttribute

public int getAttribute(String uri,
                        String local)

Description copied from interface: UnmarshallingContext

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

Specified by:

getAttribute in interface UnmarshallingContext

Parameters:

uri,local - has to be interned.

Returns:

-1 if not found.

consumeAttribute

public void consumeAttribute(int idx)
                      throws SAXException

Description copied from interface: UnmarshallingContext

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

Specified by:

consumeAttribute in interface UnmarshallingContext

Throws:

SAXException

eatAttribute

public String eatAttribute(int idx)
                    throws SAXException

Description copied from interface: UnmarshallingContext

Specified by:

eatAttribute in interface UnmarshallingContext

Throws:

SAXException

addPatcher

public void addPatcher(Runnable job)

Description copied from interface: UnmarshallingContext

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.

Specified by:

addPatcher in interface UnmarshallingContext

Parameters:

job - The run method of this object is called.

addToIdTable

public String addToIdTable(String id)

Description copied from interface: UnmarshallingContext

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

Specified by:

addToIdTable in interface UnmarshallingContext

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

public Object getObjectFromId(String id)

Description copied from interface: UnmarshallingContext

Looks up the ID table and gets associated object.

Specified by:

getObjectFromId in interface UnmarshallingContext

Returns:

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

skippedEntity

public void skippedEntity(String name)

Specified by:

skippedEntity in interface ContentHandler

processingInstruction

public void processingInstruction(String target,
                                  String data)

public Locator getLocator()

Description copied from interface: UnmarshallingContext

Gets the current source location information.

Specified by:

getLocator in interface UnmarshallingContext

handleEvent

public void handleEvent(ValidationEvent event,
                        boolean canRecover)
                 throws SAXException

Description copied from interface: SAXUnmarshallerHandler

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.

Specified by:

handleEvent in interface SAXUnmarshallerHandler

Specified by:

handleEvent in interface UnmarshallingContext

Throws:

SAXException

public String getBaseUri()

Specified by:

getBaseUri in interface UnmarshallingContext
