Method Details

marshal
Description copied from class:BinderMarshal a Jakarta XML Binding object tree to a new XML document.This method is similar to
Marshaller.marshal(Object, Node)with the addition of maintaining the association between Jakarta XML Binding objects and the produced XML nodes, enabling future update operations such asBinder.updateXML(Object, Object)orBinder.updateJAXB(Object).When
Binder.getSchema()is non-null, the marshalled xml content is validated during this operation.- Specified by:
marshalin classBinder<XmlNode>- Parameters:
jaxbObject- The content tree to be marshalled.xmlNode- The parameter must be a Node that accepts children.- Throws:
JAXBException- If any unexpected problem occurs during the marshalling.MarshalException- If theValidationEventHandlerreturns false from itshandleEventmethod or theBinderis unable to marshaljaxbObject(or any object reachable fromjaxbObject).
-
updateJAXB
Description copied from class:BinderTakes an XML node and updates its associated Jakarta XML Binding object and its descendants.This operation can be thought of as an "in-place" unmarshalling. The difference is that instead of creating a whole new Jakarta XML Binding tree, this operation updates an existing tree, reusing as much Jakarta XML Binding objects as possible.
As a side effect, this operation updates the association between XML nodes and Jakarta XML Binding objects.
- Specified by:
updateJAXBin classBinder<XmlNode>- Parameters:
xmlNode- the XML node- Returns:
- Returns the updated Jakarta XML Binding object. Typically, this is the same
object that was returned from earlier
Binder.marshal(Object,Object)orBinder.updateJAXB(Object)method invocation, but it maybe a different object, for example when the name of the XML element has changed. - Throws:
JAXBException- If any unexpected problem occurs updating corresponding Jakarta XML Binding mapped content.
-
unmarshal
Description copied from class:BinderUnmarshal XML infoset view to a Jakarta XML Binding object tree.This method is similar to
Unmarshaller.unmarshal(Node)with the addition of maintaining the association between XML nodes and the produced Jakarta XML Binding objects, enabling future update operations,Binder.updateXML(Object, Object)orBinder.updateJAXB(Object).When
Binder.getSchema()is non-null,xmlNodeand its descendants is validated during this operation.This method throws
UnmarshalExceptionwhen the Binder'sJAXBContextdoes not have a mapping for the XML element name or the type, specifiable via@xsi:type, ofxmlNodeto a Jakarta XML Binding mapped class. The methodBinder.unmarshal(Object, Class)enables an application to specify the Jakarta XML Binding mapped class that thexmlNodeshould be mapped to.- Specified by:
unmarshalin classBinder<XmlNode>- Parameters:
xmlNode- the document/element to unmarshal XML data from.- Returns:
- the newly created root object of the Jakarta XML Binding object tree.
- Throws:
JAXBException- If any unexpected errors occur while unmarshallingUnmarshalException- If theValidationEventHandlerreturns false from itshandleEventmethod or theBinderis unable to perform the XML to Java binding.
-
unmarshal
Description copied from class:BinderUnmarshal XML root element by provideddeclaredTypeto a Jakarta XML Binding object tree.Implements Unmarshal by Declared Type
This method is similar to
Unmarshaller.unmarshal(Node, Class)with the addition of maintaining the association between XML nodes and the produced Jakarta XML Binding objects, enabling future update operations,Binder.updateXML(Object, Object)orBinder.updateJAXB(Object).When
Binder.getSchema()is non-null,xmlNodeand its descendants is validated during this operation.- Specified by:
unmarshalin classBinder<XmlNode>- Type Parameters:
T- the declared type- Parameters:
xmlNode- the document/element to unmarshal XML data from.expectedType- appropriate Jakarta XML Binding mapped class to holdnode's XML data.- Returns:
- JAXBElement representation
of
node - Throws:
JAXBException- If any unexpected errors occur while unmarshallingUnmarshalException- If theValidationEventHandlerreturns false from itshandleEventmethod or theBinderis unable to perform the XML to Java binding.
-
setSchema
Description copied from class:BinderSpecifies whether marshal, unmarshal and update methods performs validation on their XML content. -
getSchema
Description copied from class:BinderGets the lastSchemaobject (including null) set by theBinder.setSchema(Schema)method. -
getXMLNode
Description copied from class:BinderGets the XML element associated with the given Jakarta XML Binding object.Once a Jakarta XML Binding object tree is associated with an XML fragment, this method enables navigation between the two trees.
An association between an XML element and a Jakarta XML Binding object is established by the bind methods and the update methods. Note that this association is partial; not all XML elements have associated Jakarta XML Binding objects, and not all Jakarta XML Binding objects have associated XML elements.
- Specified by:
getXMLNodein classBinder<XmlNode>- Parameters:
jaxbObject- An instance that is reachable from a prior call to a bind or update method that returned a Jakarta XML Binding object tree.- Returns:
- null if the specified Jakarta XML Binding object is not known to this
Binder, or if it is not associated with an XML element.
-
getJAXBNode
Description copied from class:BinderGets the Jakarta XML Binding object associated with the given XML element.Once a Jakarta XML Binding object tree is associated with an XML fragment, this method enables navigation between the two trees.
An association between an XML element and a Jakarta XML Binding object is established by the unmarshal, marshal and update methods. Note that this association is partial; not all XML elements have associated Jakarta XML Binding objects, and not all Jakarta XML Binding objects have associated XML elements.
- Specified by:
getJAXBNodein classBinder<XmlNode>- Parameters:
xmlNode- the XML element- Returns:
- null if the specified XML node is not known to this
Binder, or if it is not associated with a Jakarta XML Binding object.
-
updateXML
Description copied from class:BinderTakes a Jakarta XML Binding object and updates its associated XML node and its descendants.This is a convenience method of:
- Specified by:
updateXMLin classBinder<XmlNode>- Parameters:
jaxbObject- the XML Binding object- Returns:
- the XML node associated with XML Binding object
- Throws:
JAXBException- If any unexpected problem occurs updating corresponding XML content.
-
updateXML
Description copied from class:BinderChanges in Jakarta XML Binding object tree are updated in its associated XML parse tree.This operation can be thought of as an "in-place" marshalling. The difference is that instead of creating a whole new XML tree, this operation updates an existing tree while trying to preserve the XML as much as possible.
For example, unknown elements/attributes in XML that were not bound to Jakarta XML Binding will be left untouched (whereas a marshalling operation would create a new tree that doesn't contain any of those.)
As a side effect, this operation updates the association between XML nodes and Jakarta XML Binding objects.
- Specified by:
updateXMLin classBinder<XmlNode>- Parameters:
jaxbObject- root of potentially modified Jakarta XML Binding object treexmlNode- root of update target XML parse tree- Returns:
- Returns the updated XML node. Typically, this is the same node you passed in as xmlNode, but it maybe a different object, for example when the tag name of the object has changed.
- Throws:
JAXBException- If any unexpected problem occurs updating corresponding XML content.
-
setEventHandler
Description copied from class:BinderAllow an application to register aValidationEventHandler.The
ValidationEventHandlerwill be called by the Jakarta XML Binding Provider if any validation errors are encountered during calls to any of the Binder unmarshal, marshal and update methods.Calling this method with a null parameter will cause the Binder to revert back to the default event handler.
- Specified by:
setEventHandlerin classBinder<XmlNode>- Parameters:
handler- the validation event handler- Throws:
JAXBException- if an error was encountered while setting the event handler
-
getEventHandler
Description copied from class:BinderReturn the current event handler or the default event handler if one hasn't been set.- Specified by:
getEventHandlerin classBinder<XmlNode>- Returns:
- the current ValidationEventHandler or the default event handler if it hasn't been set
-
setMarshallerListener
-
getMarshallerListener
-
setUnmarshallerListener
-
getUnmarshallerListener
-
getProperty
Description copied from class:BinderGet the particular property in the underlying implementation ofBinder. This method can only be used to get one of the standard Jakarta XML Binding defined unmarshal/marshal properties or a provider specific property for binder, unmarshal or marshal. Attempting to get an undefined property will result in a PropertyException being thrown. See Supported Unmarshal Properties and Supported Marshal Properties.- Specified by:
getPropertyin classBinder<XmlNode>- Parameters:
name- the name of the property to retrieve- Returns:
- the value of the requested property
- Throws:
PropertyException- when there is an error retrieving the given property or value property name
-
setProperty
Description copied from class:BinderSet the particular property in the underlying implementation ofBinder. This method can only be used to set one of the standard Jakarta XML Binding defined unmarshal/marshal properties or a provider specific property for binder, unmarshal or marshal. Attempting to set an undefined property will result in a PropertyException being thrown. See Supported Unmarshal Properties and Supported Marshal Properties.- Specified by:
setPropertyin classBinder<XmlNode>- Parameters:
name- the name of the property to be set. This value can either be specified using one of the constant fields or a user supplied string.value- the value of the property to be set- Throws:
PropertyException- when there is an error processing the given property or value
