Implements: Unmarshaller

部分默认 Unmarshaller 实现。

此类提供 javax.xml.bind.Unmarshaller 接口的部分默认实现。

JAXB 提供者必须实现 5 个方法:getUnmarshallerHandler、unmarshal(Node)、unmarshal(XMLReader,InputSource)、unmarshal(XMLStreamReader) 和 unmarshal(XMLEventReader)。

英文文档:

Partial default Unmarshaller implementation.

This class provides a partial default implementation for the Unmarshallerinterface.

A JAXB Provider has to implement five methods (getUnmarshallerHandler, unmarshal(Node), unmarshal(XMLReader,InputSource), unmarshal(XMLStreamReader), and unmarshal(XMLEventReader).

public AbstractUnmarshallerImpl()
Method Detail

protected org.xml.sax.XMLReader getXMLReader() throws JAXBException
获取配置好的 XMLReader。 此方法在客户端指定的 SAXSource 对象没有 XMLReader 时使用。 Unmarshaller 不可重入,因此我们只能使用一个 XMLReader 实例。
英文文档:

getXMLReader

protected XMLReader getXMLReader()
                          throws JAXBException
Obtains a configured XMLReader. This method is used when the client-specified SAXSource object doesn't have XMLReader. Unmarshaller is not re-entrant, so we will only use one instance of XMLReader.

Throws:
JAXBException

public Object unmarshal(javax.xml.transform.Source source) throws JAXBException
英文文档:

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 JAXB provider. Any SAX 2.0 compliant parser can be substituted for the JAXB 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 JAXB Provider so that validation errors can be reported via the ValidationEventHandler mechanism of JAXB. If the SAXSource does not contain an XMLReader, then the JAXB provider's default parser mechanism will be used.

This parser replacement mechanism can also be used to replace the JAXB 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 JAXB provider and converted into JAXB 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 JAXB 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 JAXB provider's default parser and validator mechanisms.

public boolean isValidating() throws JAXBException
指示 Unmarshaller 是否被配置为在执行解组操作期间进行验证。

注: 为了与 JAXP 保持一致,我将该方法命名为 isValidating(),而不是 getValidating()。

return 如果 Unmarshaller 被配置为在执行解组操作期间进行验证,则返回 true,否则返回 false
ThrowsJAXBException: 如果检索验证标志时发生错误

英文文档:

isValidating

public boolean isValidating()
                     throws JAXBException
Indicates whether or not the Unmarshaller is configured to validate during unmarshal operations.

Note: I named this method isValidating() to stay in-line with JAXP, as opposed to naming it getValidating().

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

public void setEventHandler(ValidationEventHandler handler) throws JAXBException
允许应用程序注册一个验证事件处理程序。

如果在调用任一 unmarshal 方法期间发生验证错误,则 JAXB 提供者将调用验证事件处理程序。如果在调用解组方法之前客户端应用程序没有注册验证事件处理程序,那么将忽略所有验证事件,并有可能导致不可预料的行为。

handler 验证事件处理程序
ThrowsJAXBException: 如果在设置事件处理程序时发生错误

英文文档:

setEventHandler

public void setEventHandler(ValidationEventHandler handler)
                     throws JAXBException
Allow an application to register a validation event handler.

The validation event handler will be called by the JAXB Provider if any validation errors are encountered during calls to any of the unmarshal methods. If the client application does not register a validation event handler before invoking the unmarshal methods, then all validation events will be silently ignored and may result in unexpected behaviour.

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

public void setValidating(boolean validating) throws JAXBException
指定 Unmarshaller 是否应该在执行解组操作期间进行验证。默认情况下,Unmarshaller 不进行验证。

此方法仅在调用某一解组方法之前或之后调用。

validating 如果 Unmarshaller 应该在执行解组操作期间进行验证,则该参数为 true,否则为 false
ThrowsJAXBException: 如果在执行解组操作期间启用或禁用验证时发生错误

英文文档:

setValidating

public void setValidating(boolean validating)
                   throws JAXBException
Specifies whether or not 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.

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

public ValidationEventHandler getEventHandler() throws JAXBException
当前的事件处理程序;如果没有设置,则返回默认事件处理程序。
return 当前 ValidationEventHandler,如果没有设置该处理程序,则返回默认的事件处理程序
ThrowsJAXBException: 如果获取当前事件处理程序时发生错误
英文文档:

getEventHandler

public ValidationEventHandler getEventHandler()
                                       throws JAXBException
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

protected UnmarshalException createUnmarshalException(org.xml.sax.SAXException e)
从 SAXException 创建 UnmarshalException。 这是一个为派生类提供的实用方法。

当提供者实现的 ContentHandler 希望抛出 JAXBException 时,它需要通过 SAXException 包装该异常。如果 unmarshaller 实现盲目地使用 JAXBException 包装 SAXException ,则异常将是用另一个 JAXBException 包装的 SAXException 包装的 JAXBException。这样做很不明智。

此方法检查 SAXException 的嵌套异常并可减少过多的包装。

return 得到的 UnmarshalException

英文文档:

createUnmarshalException

protected UnmarshalException createUnmarshalException(SAXException e)
Creates an UnmarshalException from a SAXException. This is an utility method provided for the derived classes.

When a provider-implemented ContentHandler wants to throw a JAXBException, it needs to wrap the exception by a SAXException. If the unmarshaller implementation blindly wrap SAXException by JAXBException, such an exception will be a JAXBException wrapped by a SAXException wrapped by another JAXBException. This is silly.

This method checks the nested exception of SAXException and reduce those excessive wrapping.

Returns:
the resulting UnmarshalException

public void setProperty(String name, Object value) throws PropertyException
由于没有必需的属性,setProperty 方法的默认实现总是抛出 PropertyException。如果提供商需要处理其他属性,则应该在派生类中重写此方法。
英文文档:

setProperty

public void setProperty(String name,
                        Object value)
                 throws PropertyException
Default implementation of the setProperty method always throws PropertyException since there are no required properties. If a provider needs to handle additional properties, it should override this method in a derived class.

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

public Object getProperty(String name) throws PropertyException
由于没有必需的属性,getProperty 方法的默认实现总是抛出 PropertyException。如果提供者需要处理其他属性,则应该在派生类中重写此方法。
英文文档:

getProperty

public Object getProperty(String name)
                   throws PropertyException
Default implementation of the getProperty method always throws PropertyException since there are no required properties. If a provider needs to handle additional properties, it should override this method in a derived class.

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

英文文档:

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.

public javax.xml.validation.Schema getSchema()
英文文档:

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;
