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.


Constructor & Destructor Documentation

ACE_RMCast_Partial_Message::ACE_RMCast_Partial_Message ACE_UINT32  message_size  ) 
 

Constructor, reserve enough memory for the complete message.

ACE_RMCast_Partial_Message::~ACE_RMCast_Partial_Message void   ) 
 

Destructor.


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.
