FRAG2.FragEntry

java.lang.Object
- org.jgroups.protocols.FRAG2.FragEntry

Enclosing class:

FRAG2
```
protected static class FRAG2.FragEntry
extends java.lang.Object
```
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.
All methods are unsynchronized, use getLock() to obtain a lock for concurrent access.

```
- Constructor Detail
  - FragEntry
```
protected FragEntry(int tot_frags)
```
    Creates a new entry
    
    Parameters:
    
    tot_frags - the number of fragments to expect for this message
- Method Detail
  - lock
```
public void lock()
```
    Use to synchronize on FragEntry
  - unlock
```
public void unlock()
```
  - set
```
public void set(int frag_id,
                Message frag)
```
    adds on fragmentation buffer to the message
    
    Parameters:
    
    frag_id - the number of the fragment being added 0..(tot_num_of_frags - 1)
    
    frag - the byte buffer containing the data for this fragmentation, should not be null
  - isComplete
```
public boolean isComplete()
```
    returns true if this fragmentation is complete ie, all fragmentations have been received for this buffer
  - assembleMessage
```
protected Message assembleMessage()
```
    Assembles all the fragments into one buffer. Takes all Messages, and combines their buffers into one buffer. This method does not check if the fragmentation is complete (use isComplete() to verify before calling this method)
    
    Returns:
    
    the complete message in one buffer
  - toString
```
public java.lang.String toString()
```
    Overrides:
    
    toString in class java.lang.Object
