An unmarshaller to allowing unmarshalling of XML documents to
Java Objects. The Class must specify
the proper access methods (setters/getters) in order for instances
of the Class to be properly unmarshalled.
Unmarshaller
public Unmarshaller()
Creates a new basic Unmarshaller
When using this constructor it will most likely be
necessary to use a mapping file or ClassDescriptorResolver
So that the Unmarshaller can find the classes during the
unmarshalling process.
Unmarshaller
public Unmarshaller(Class c)
Creates a new Unmarshaller with the given Class
c
- the Class to create the Unmarshaller for, this
may be null, if the Unmarshaller#setMapping is called
to load a mapping for the root element of xml document.
Unmarshaller
public Unmarshaller(Class c,
ClassLoader loader)
Creates a new Unmarshaller with the given Class
c
- the Class to create the Unmarshaller for, this
may be null, if the Unmarshaller#setMapping is called
to load a mapping for the root element of xml document.
Unmarshaller
public Unmarshaller(Object root)
Creates a new Unmarshaller with the given Object
root
- the instance to unmarshal into. This
may be null, if the Unmarshaller#setMapping is called
to load a mapping for the root element of xml document.
Unmarshaller
public Unmarshaller(Mapping mapping)
throws MappingException
Creates a new Unmarshaller with the given Mapping
createHandler
public UnmarshalHandler createHandler()
Creates and initalizes an UnmarshalHandler
getContentHandler
public static ContentHandler getContentHandler(UnmarshalHandler handler)
throws SAXException
Wraps the given UnmarshalHandler with a SAX 2 ContentHandler.
Allows for improved integration with SAX 2 applications
setClassLoader
public void setClassLoader(ClassLoader loader)
Sets the ClassLoader to use when loading new classes.
Note:This ClassLoader is used for classes
loaded by the unmarshaller only. If a Mapping has
been set, the Mapping has it's own ClassLoader and
may also need to be set propertly.
loader
- the ClassLoader to use
setClearCollections
public void setClearCollections(boolean clear)
Sets whether or not to clear collections (including arrays)
upon first use to remove default values. By default, and
for backward compatibility with previous versions of Castor
this value is false, indicating that collections are not
cleared before initial use by Castor.
clear
- the boolean value that when true indicates
collections should be cleared upon first use.
setDebug
public void setDebug(boolean debug)
Turns debuging on or off. If no Log Writer has been set, then
System.out will be used to display debug information
debug
- the flag indicating whether to generate debug information.
A value of true, will turn debuggin on.
setEntityResolver
public void setEntityResolver(EntityResolver entityResolver)
Sets the EntityResolver to use when resolving system and
public ids with respect to entites and Document Type.
entityResolver
- the EntityResolver to use when
resolving System and Public ids.
setIDResolver
public void setIDResolver(IDResolver idResolver)
Sets the IDResolver to use when resolving IDREFs for
which no associated element may exist in XML document.
idResolver
- the IDResolver to use when resolving
IDREFs for which no associated element may exist in the
XML document.
setIgnoreExtraAttributes
public void setIgnoreExtraAttributes(boolean ignoreExtraAtts)
Sets whether or not attributes that do not match
a specific field should simply be ignored or
reported as an error. By default, extra attributes
are ignored.
ignoreExtraAtts
- a boolean that when true will
allow non-matched attributes to simply be ignored.
setIgnoreExtraElements
public void setIgnoreExtraElements(boolean ignoreExtraElements)
Sets whether or not elements that do not match
a specific field should simply be ignored or
reported as an error. By default, extra elements
are flagged as an error.
ignoreExtraElements
- a boolean that when true will
allow non-matched elements to simply be ignored.
setLogWriter
public void setLogWriter(PrintWriter printWriter)
Sets the PrintWriter used for logging
printWriter
- the PrintWriter to use for logging
setMapping
public void setMapping(Mapping mapping)
throws MappingException
Sets the Mapping to use during unmarshalling. If the
Mapping has a ClassLoader it will be used during
unmarshalling.
mapping
- the Mapping to use during unmarshalling.
setResolver
public void setResolver(ClassDescriptorResolver cdr)
Sets the ClassDescriptorResolver to use during unmarshalling
cdr
- the ClassDescriptorResolver to use
setReuseObjects
public void setReuseObjects(boolean reuse)
Sets a boolean that when true indicates that objects
contained within the object model should be re-used
where appropriate. This is only valid when unmarshalling
to an existing object.
reuse
- the boolean indicating whether or not
to re-use existing objects in the object model.
setUnmarshalListener
public void setUnmarshalListener(UnmarshalListener listener)
Sets an optional
UnmarshalListener
to receive pre and
post unmarshal notification for each Object in the tree.
An UnmarshalListener is often used to allow objects to
appropriately initialize themselves by taking appliction
specific behavior as they are unloaded.
Current only one (1) listener is allowed. If you need
register multiple listeners, you will have to create
your own master listener that will forward the
event notifications and manage the multiple
listeners.
setValidation
public void setValidation(boolean validate)
Sets the flag for validation
unmarshal
public static Object unmarshal(Class c,
InputSource source)
throws MarshalException,
ValidationException
Unmarshals Objects of the given Class type. The Class must specify
the proper access methods (setters/getters) in order for instances
of the Class to be properly unmarshalled.
c
- the Class to create a new instance ofsource
- the InputSource to read the XML from
unmarshal
public static Object unmarshal(Class c,
Node node)
throws MarshalException,
ValidationException
