  Constructor Detail

  CMSRecipientInfo

  public CMSRecipientInfo()
  

  Create an empty CMSRecipientInfo.

  CMSRecipientInfo

  public CMSRecipientInfo(java.io.InputStream is)
                   throws java.io.IOException
  

  Create a new CMSRecipientInfo by reading the BER encoding from the specified input stream.

  Parameters:

  is - The input stream.

  Throws:

  java.io.IOException - The encoding is incorrect or an I/O error occurs.

  Method Detail

  input

  public void input(java.io.InputStream is)
             throws java.io.IOException
  

  Read the BER encoded CMSRecipientInfo structure from the input stream.

  Parameters:

  is - The input stream.

  Throws:

  java.io.IOException - The input encoding is incorrect or an I/O error occurs.

  inputInstance

  public static CMSRecipientInfo inputInstance(java.io.InputStream is)
                                        throws java.io.IOException
  

  Create and intialize a CMSRecipientInfo by reading the BER encoding from the specified input stream.

  Parameters:

  is - The input stream.

  Returns:

  The CMSRecipientInfo Object.

  Throws:

  java.io.IOException - The encoding is incorrect or an I/O error occurs.

  inputRecipientInfo

  protected abstract void inputRecipientInfo(java.io.InputStream is)
                                      throws java.io.IOException
  

  Reads the CMSRecipientInfo structure. This method must be implemented by subclasses.

  The input stream is positioned at the beginning of the tag octet of the SEQUENCE encoding.

  Parameters:

  is - The input stream.

  Throws:

  java.io.IOException - The encoding is incorrect or an I/O error occurs.

  getVersion

  public abstract ASN1Integer getVersion()
  

  Returns the Version of the CMSRecipientInfo. This method must be implemented by subclasses.

  Returns:

  The version number.
