java.lang.Object
org.jivesoftware.smackx.si.packet.StreamInitiation.File
All Implemented Interfaces:
Element, ExtensionElement, NamedElement, XmlElement, XmlLangElement
Enclosing class:
StreamInitiation
public static class StreamInitiation.File extends Object implements ExtensionElement
  • size: The size, in bytes, of the data to be sent.
  • name: The name of the file that the Sender wishes to send.
  • date: The last modification time of the file. This is specified using the DateTime profile as described in Jabber Date and Time Profiles.
  • hash: The MD5 sum of the file contents.

<desc> is used to provide a sender-generated description of the file so the receiver can better understand what is being sent. It MUST NOT be sent in the result.

When <range> is sent in the offer, it should have no attributes. This signifies that the sender can do ranged transfers. When a Stream Initiation result is sent with the <range> element, it uses these attributes:

  • offset: Specifies the position, in bytes, to start transferring the file data from. This defaults to zero (0) if not specified.
  • length - Specifies the number of bytes to retrieve starting at offset. This defaults to the length of the file from offset to the end.
Both attributes are OPTIONAL on the <range> element. Sending no attributes is synonymous with not sending the <range> element. When no <range> element is sent in the Stream Initiation result, the Sender MUST send the complete file starting at offset 0. More generally, data is sent over the stream byte for byte starting at the offset position for the length specified.
