org.jgroups.protocols.FRAG.FragmentationTable
- Enclosing class:
- FRAG
- static class FRAG.FragmentationTable
- extends java.lang.Object
Keeps track of the fragments that are received.
Reassembles fragements into entire messages when all fragments have been received.
The fragmentation holds a an array of byte arrays for a unique sender
The first dimension of the array is the order of the fragmentation, in case the arrive out of order

FRAG.FragmentationTable.Entry
inner class represents an entry for a message
each entry holds an array of byte arrays sorted
once all the byte buffer entries have been filled
the fragmentation is considered complete. |

FRAG.FragmentationTable
FRAG.FragmentationTable(org.jgroups.Address sender)
add
public byte[] add(long id,
int frag_id,
int tot_frags,
byte[] fragment)
- Creates a new entry if not yet present. Adds the fragment.
If all fragements for a given message have been received,
an entire message is reassembled and returned.
Otherwise null is returned.
reset
public void reset()
toString
public java.lang.String toString()
- Description copied from class:
java.lang.Object
- Convert this Object to a human-readable String.
There are no limits placed on how long this String
should be or what it should contain. We suggest you
make it as intuitive as possible to be able to place
it into System.out.println() 55
and such.
It is typical, but not required, to ensure that this method
never completes abruptly with a java.lang.RuntimeException.
This method will be called when performing string
concatenation with this object. If the result is
null, string concatenation will instead
use "null".
The default implementation returns
getClass().getName() + "@" +
Integer.toHexString(hashCode()).
