public interface ToDomConverter
Classes that implement this interface are capable of converting an object type (or types) into a DOM tree.
Method Summary | |
---|---|
boolean |
toElement(ObjectWrapper wrapper,
org.w3c.dom.Element element,
java.lang.Class type,
Object2Dom o2d)
Populates the specified Element according to the state
of the object in the ObjectWrapper using the specified
Object2Dom instance for recursion. |
boolean |
toObject(ObjectWrapper wrapper,
org.w3c.dom.Element element,
java.lang.Class type,
Object2Dom o2d)
Creates an object of the given type that is
represented by the contents of the specified Element
parameter. |

boolean toElement(ObjectWrapper wrapper, org.w3c.dom.Element element, java.lang.Class type, Object2Dom o2d)
Element
according to the state
of the object in the ObjectWrapper
using the specified
Object2Dom
instance for recursion.
Implementations of this method should first check the specified
type
to determine if conversion is supported
for that type.
wrapper
- The ObjectWrapper
containing the object
to be converted.element
- The parent Element
to which any newly
created Element
s should be appended.type
- The Class
type of the object being converted
to an Element
.o2d
- The Object2Dom
instance to use for recursion,
if necessary.
true
if the conversion from object to
Element
occurred successfully; false
otherwise.boolean toObject(ObjectWrapper wrapper, org.w3c.dom.Element element, java.lang.Class type, Object2Dom o2d)
type
that is
represented by the contents of the specified Element
parameter. The given Object2Dom
is used for recursing
into other objects.
Implementations of this method should first check the specified
type
to determine if conversion is supported
for that type.
The object produced by this method must be set on the specified
ObjectWrapper
before this method returns. Additionally,
if the ObjectWrapper
already contains an object when
this method is invoked, this method should unmarshal the
specified Element
's state into the existing object
rather than creating a new one, if possible.
wrapper
- The ObjectWrapper
that wraps the object
that results from unmarshalling the specified Element
. If
a pre-existing object is in the ObjectWrapper
, this method
should attempt to unmarshal the Element
into the existing
object rather than creating a new one.element
- The Element
which is being unmarshalled
into an object.type
- The Class
type of the object being
unmarshalled from an Element
.o2d
- The Object2Dom
instance to use for recursion,
if necessary.
true
if the conversion from Element
to object occurred successfully; false
otherwise.
