Method Detail

beanToXml

public void beanToXml(Object bean,
                      OutputStream destiny,
                      String jaxbContext)
               throws XmlHandlerException

Serializes the content of a given object to an OutputStream.

Specified by:

beanToXml in interface XmlHandler

Parameters:

bean - The object to be serialized in form of XML file.

destiny - The destination (as OutputStream) of the XML file to be serialized.

jaxbContext - The context of the XML file. For instance, for the JaxbXmlHandler implementation, the context is the package where the objects that represent the XML structure are located.

Throws:

XmlHandlerException - If any problem occur when trying to serialize the object.

xmlToBean

public Object xmlToBean(InputStream source,
                        String jaxbContext)
                 throws XmlHandlerException

Retrieves the content of a given XML file as an Object.

Specified by:

xmlToBean in interface XmlHandler

Parameters:

source - The XML file to be read, as InputStream.

jaxbContext - The context of the XML file. For instance, for the JaxbXmlHandler implementation, the context is the package where the objects that represent the XML structure are located.

Returns:

The structure of the XML file as an Object.

Throws:

XmlHandlerException - If any problem occur when trying to read the XML file and transform it to an Object representation.
