      • getEventHandler

        public ValidationEventHandler getEventHandler()
                                       throws JAXBException
        Description copied from interface: Unmarshaller
        Return the current event handler or the default event handler if one hasn't been set.
        Specified by:
        getEventHandler in interface Unmarshaller
        Returns:
        the current ValidationEventHandler or the default event handler if it hasn't been set
        Throws:
        JAXBException - if an error was encountered while getting the current event handler

      • getProperty

        public Object getProperty​(String name)
                   throws PropertyException
        Description copied from interface: Unmarshaller
        Get the particular property in the underlying implementation of Unmarshaller. This method can only be used to get one of the standard Jakarta XML Binding defined properties above or a provider specific property. Attempting to get an undefined property will result in a PropertyException being thrown. See Supported Properties.
        Specified by:
        getProperty in interface Unmarshaller
        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

      • getSchema

        public Schema getSchema()
        Description copied from interface: Unmarshaller
        Get the JAXP 1.3 Schema object being used to perform unmarshal-time validation. If there is no Schema set on the unmarshaller, then this method will return null indicating that unmarshal-time validation will not be performed.

        This method provides replacement functionality for the deprecated Unmarshaller.isValidating() API as well as access to the Schema object. To determine if the Unmarshaller has validation enabled, simply test the return type for null: 

        
   boolean isValidating = u.getSchema()!=null;
        Specified by:
        getSchema in interface Unmarshaller
        Returns:
        the Schema object being used to perform unmarshal-time validation or null if not present

      • getUnmarshallerHandler

        public UnmarshallerHandler getUnmarshallerHandler()
        Description copied from interface: Unmarshaller
        Get an unmarshaller handler object that can be used as a component in an XML pipeline.

        The Jakarta XML Binding Provider can return the same handler object for multiple invocations of this method. In other words, this method does not necessarily create a new instance of UnmarshallerHandler. If the application needs to use more than one UnmarshallerHandler, it should create more than one Unmarshaller.

        Specified by:
        getUnmarshallerHandler in interface Unmarshaller
        Returns:
        the unmarshaller handler object
        See Also:
        UnmarshallerHandler

      • isValidating

        @Deprecated
public boolean isValidating()
                     throws JAXBException
        Deprecated.
        This method is deprecated as of JAXB 2.0 - please use the new getSchema() API.
        Description copied from interface: Unmarshaller
        Indicates whether or not the Unmarshaller is configured to validate during unmarshal operations.

        This API returns the state of the Jakarta XML Binding Provider's default unmarshal-time validation mechanism.

        This method is deprecated as of Jakarta XML Binding - please use the new Unmarshaller.getSchema() API.

        Specified by:
        isValidating in interface Unmarshaller
        Returns:
        true if the Unmarshaller is configured to validate during unmarshal operations, false otherwise
        Throws:
        JAXBException - if an error occurs while retrieving the validating flag

      • setAdapter

        public <A extends XmlAdapter> void setAdapter​(Class<A> type,
                                              A adapter)
        Description copied from interface: Unmarshaller
        Associates a configured instance of XmlAdapter with this unmarshaller.

        Every unmarshaller internally maintains a Map<Class,XmlAdapter>, which it uses for unmarshalling classes whose fields/methods are annotated with XmlJavaTypeAdapter.

        This method allows applications to use a configured instance of XmlAdapter. When an instance of an adapter is not given, an unmarshaller will create one by invoking its default constructor.

        Specified by:
        setAdapter in interface Unmarshaller
        Parameters:
        type - The type of the adapter. The specified instance will be used when XmlJavaTypeAdapter.value() refers to this type.
        adapter - The instance of the adapter to be used. If null, it will un-register the current adapter set for this type.

      • setEventHandler

        public void setEventHandler​(ValidationEventHandler handler)
                     throws JAXBException
        Description copied from interface: Unmarshaller
        Allow an application to register a ValidationEventHandler.

        The ValidationEventHandler will be called by the Jakarta XML Binding Provider if any validation errors are encountered during calls to any of the unmarshal methods. If the client application does not register a ValidationEventHandler before invoking the unmarshal methods, then ValidationEvents will be handled by the default event handler which will terminate the unmarshal operation after the first error or fatal error is encountered.

        Calling this method with a null parameter will cause the Unmarshaller to revert back to the default event handler.

        Specified by:
        setEventHandler in interface Unmarshaller
        Parameters:
        handler - the validation event handler
        Throws:
        JAXBException - if an error was encountered while setting the event handler

      • setProperty

        public void setProperty​(String name,
                        Object value)
                 throws PropertyException
        Description copied from interface: Unmarshaller
        Set the particular property in the underlying implementation of Unmarshaller. This method can only be used to set one of the standard Jakarta XML Binding defined properties above or a provider specific property. Attempting to set an undefined property will result in a PropertyException being thrown. See Supported Properties.
        Specified by:
        setProperty in interface Unmarshaller
        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

      • setSchema

        public void setSchema​(Schema schema)
        Description copied from interface: Unmarshaller
        Specify the JAXP 1.3 Schema object that should be used to validate subsequent unmarshal operations against. Passing null into this method will disable validation.

        This method replaces the deprecated setValidating(boolean) API.

        Initially this property is set to null.

        Specified by:
        setSchema in interface Unmarshaller
        Parameters:
        schema - Schema object to validate unmarshal operations against or null to disable validation

      • setValidating

        @Deprecated
public void setValidating​(boolean validating)
                   throws JAXBException
        Deprecated.
        since JAXB2.0, please see getSchema()
        Description copied from interface: Unmarshaller
        Specifies whether or not the default validation mechanism of the Unmarshaller should validate during unmarshal operations. By default, the Unmarshaller does not validate.

        This method may only be invoked before or after calling one of the unmarshal methods.

        This method only controls the Jakarta XML Binding Provider's default unmarshal-time validation mechanism - it has no impact on clients that specify their own validating SAX 2.0 compliant parser. Clients that specify their own unmarshal-time validation mechanism may wish to turn off the Jakarta XML Binding Provider's default validation mechanism via this API to avoid "double validation".

        This method is deprecated as of Jakarta XML Binding - please use the new Unmarshaller.setSchema(javax.xml.validation.Schema) API.

        Specified by:
        setValidating in interface Unmarshaller
        Parameters:
        validating - true if the Unmarshaller should validate during unmarshal, false otherwise
        Throws:
        JAXBException - if an error occurred while enabling or disabling validation at unmarshal time

      • unmarshal

        public Object unmarshal​(Reader reader)
                 throws JAXBException
        Description copied from interface: Unmarshaller
        Unmarshal XML data from the specified Reader and return the resulting content tree. Validation event location information may be incomplete when using this form of the unmarshal API, because a Reader does not provide the system ID.

        Implements Unmarshal Global Root Element.

        Specified by:
        unmarshal in interface Unmarshaller
        Parameters:
        reader - the Reader to unmarshal XML data from
        Returns:
        the newly created root object of the java content tree
        Throws:
        JAXBException - If any unexpected errors occur while unmarshalling
        UnmarshalException - If the ValidationEventHandler returns false from its handleEvent method or the Unmarshaller is unable to perform the XML to Java binding. See Unmarshalling XML Data

      • unmarshal

        public Object unmarshal​(Source source)
                 throws JAXBException
        Description copied from interface: Unmarshaller
        Unmarshal XML data from the specified XML Source and return the resulting content tree.

        Implements Unmarshal Global Root Element.

        SAX 2.0 Parser Pluggability

        A client application can choose not to use the default parser mechanism supplied with their Jakarta XML Binding provider. Any SAX 2.0 compliant parser can be substituted for the Jakarta XML Binding provider's default mechanism. To do so, the client application must properly configure a SAXSource containing an XMLReader implemented by the SAX 2.0 parser provider. If the XMLReader has an org.xml.sax.ErrorHandler registered on it, it will be replaced by the Jakarta XML Binding Provider so that validation errors can be reported via the ValidationEventHandler mechanism of Jakarta XML Binding. If the SAXSource does not contain an XMLReader, then the Jakarta XML Binding provider's default parser mechanism will be used.

        This parser replacement mechanism can also be used to replace the Jakarta XML Binding provider's unmarshal-time validation engine. The client application must properly configure their SAX 2.0 compliant parser to perform validation (as shown in the example above). Any SAXParserExceptions encountered by the parser during the unmarshal operation will be processed by the Jakarta XML Binding provider and converted into Jakarta XML Binding ValidationEvent objects which will be reported back to the client via the ValidationEventHandler registered with the Unmarshaller. Note: specifying a substitute validating SAX 2.0 parser for unmarshalling does not necessarily replace the validation engine used by the Jakarta XML Binding provider for performing on-demand validation.

        The only way for a client application to specify an alternate parser mechanism to be used during unmarshal is via the unmarshal(SAXSource) API. All other forms of the unmarshal method (File, URL, Node, etc) will use the Jakarta XML Binding provider's default parser and validator mechanisms.

        Specified by:
        unmarshal in interface Unmarshaller
        Parameters:
        source - the XML Source to unmarshal XML data from (providers are only required to support SAXSource, DOMSource, and StreamSource)
        Returns:
        the newly created root object of the java content tree
        Throws:
        JAXBException - If any unexpected errors occur while unmarshalling
        UnmarshalException - If the ValidationEventHandler returns false from its handleEvent method or the Unmarshaller is unable to perform the XML to Java binding. See Unmarshalling XML Data

                             throws JAXBException
        Description copied from interface: Unmarshaller
        Unmarshal root element to Jakarta XML Binding mapped declaredType and return the resulting content tree.

        This method implements unmarshal by declaredType.

        This method assumes that the parser is on a START_DOCUMENT or START_ELEMENT event. Unmarshalling will be done from this start event to the corresponding end event. If this method returns successfully, the reader will be pointing at the token right after the end event.

        Specified by:
        unmarshal in interface Unmarshaller
        Parameters:
        reader - The parser to be read.
        declaredType - appropriate Jakarta XML Binding mapped class to hold reader's START_ELEMENT XML data.
        Returns:
        content tree rooted by JAXBElement representation
        Throws:
        JAXBException - If any unexpected errors occur while unmarshalling
        UnmarshalException - If the ValidationEventHandler returns false from its handleEvent method or the Unmarshaller is unable to perform the XML to Java binding. See Unmarshalling XML Data
