public class pkcs10_content
extends java.lang.Object
implements jakarta.activation.DataContentHandler
Within the JavaBeans Activation Framework (JAF) data content handlers are used for writing certain data objects to streams, and parsing objects back from streams. Generally, applications do not immediately call the methods of a data content handler. Rather they use the access mechanisms provided by the corresponding DataHandler. The data handler itself internally will look for a proper data content handler supporting a the requested S/MIME type.
The JAF uses a RFC 1524
mailcap file for defining Java classes as content handlers for specific mime types.
In particular, this pkcs10_content
class acts as a content handler for the S/MIME
types application/x-pkcs10 and - the newer one - application/pkcs10, indicated by
the following statements in the corresponding mailcap file:
application/x-pkcs10;; x-java-content-handler=iaik.smime.pkcs10_content application/pkcs10;; x-java-content-handler=iaik.smime.pkcs10_contentNote that the IAIK-S/MIME distribution includes a ready-to-use mailcap file to be copied in the lib directory of your JDK (<JDK-INSTALL>/lib)!

dataFlavor
- the DataFlavor indicating the requested typedataSource
- the DataSource supplying the encapsulated dataPKCS10Content
or
for the supplied datajava.io.IOException
- if an error occurs when parsing the datapublic java.lang.Object getContent(jakarta.activation.DataSource dataSource) throws java.io.IOException

dataSource
- the data source supplying the encapsulated dataPKCS10Content
object
representing the supplied datajava.io.IOException
- if an error occurs when parsing the datapublic void writeTo(java.lang.Object o, java.lang.String mimeType, java.io.OutputStream os) throws java.io.IOException
This method only is able to handle objects supplied as instances
of PKCS10Content
. If
the given object does not satisfy this criterion, an IOException
is thrown.
writeTo
in interface jakarta.activation.DataContentHandler
o
- the object (an instance of PKCS10Content) to
be written to the streammimeType
- the mimeType; not used hereos
- the output stream to which to write the datajava.io.IOException
- if the supplied object is not an instance of
PKCS10Content, or an error occurs while
writing to the stream
