Detailed Description

This class provides temporary storage for the fragments as they are received in the ACE_RMCast_Reassembly module. It also keeps track of what portions of the message are still missing.

Member Function Documentation

int ACE_RMCast_Partial_Message::fragment_received (  ACE_UINT32  message_size, ACE_UINT32  offset, ACE_Message_Block *  mb )

Process a fragment. A fragment starting at <offset> has been received, copy the fragment contents and update the list of holes.

int ACE_RMCast_Partial_Message::insert_hole (  size_t  i, ACE_UINT32  start, ACE_UINT32  end )  [private]

Insert a new hole into the list. The class keeps an array to represent the missing portions of the message. This method inserts a new hole, i.e. a new element in the array at index . The <start> and <end> arguments represent the offsets of the missing portion of the message.

ACE_INLINE int ACE_RMCast_Partial_Message::is_complete (  void   )  const

Return 1 if the message is complete.

ACE_INLINE ACE_Message_Block * ACE_RMCast_Partial_Message::message_body (  void   )

Return the body of the message, the memory is *not* owned by the caller

int ACE_RMCast_Partial_Message::remove_hole (  size_t  i  )  [private]

Remove a hole from the list.
