- Method Detail
  - reason
```
@Nullable
@Nullable String reason()
```
    Returns:
    
    Description of the reason of the current checkpoint.
  - inProgress
```
boolean inProgress()
```
    Returns:
    
    true if the current checkpoint is in CheckpointState which shows that checkpoint has already started but not finished yet.
  - futureFor
```
GridFutureAdapter futureFor(CheckpointState state)
```
    Returns:
    
    The future which can be used for detection when current checkpoint reaches the specific state.
  - fail
```
void fail(Throwable error)
```
    Mark this checkpoint execution as failed.
    
    Parameters:
    
    error - Causal error of fail.
  - transitTo
```
void transitTo(@NotNull
               @NotNull CheckpointState newState)
```
    Changing checkpoint state if order of state is correct.
    
    Parameters:
    
    newState - New checkpoint state.
  - getDestroyQueue
```
PartitionDestroyQueue getDestroyQueue()
```
    Returns:
    
    PartitionDestroyQueue.
  - writtenPagesCounter
```
AtomicInteger writtenPagesCounter()
```
    Returns:
    
    Counter for written checkpoint pages. Not null only if checkpoint is running.
  - syncedPagesCounter
```
AtomicInteger syncedPagesCounter()
```
    Returns:
    
    Counter for fsynced checkpoint pages. Not null only if checkpoint is running.
  - evictedPagesCounter
```
AtomicInteger evictedPagesCounter()
```
    Returns:
    
    Counter for evicted pages during current checkpoint. Not null only if checkpoint is running.
  - currentCheckpointPagesCount
```
int currentCheckpointPagesCount()
```
    Returns:
    
    Number of pages in current checkpoint. If checkpoint is not running, returns 0.
  - currentCheckpointPagesCount
```
void currentCheckpointPagesCount(int num)
```
    Sets current checkpoint pages num to store.
    
    Parameters:
    
    num - Pages to store.
  - initCounters
```
void initCounters(int pagesSize)
```
    Initialize all counters before checkpoint.
  - updateSyncedPages
```
void updateSyncedPages(int delta)
```
    Update synced pages in checkpoint;
    
    Parameters:
    
    delta - Pages num to update.
  - updateWrittenPages
```
void updateWrittenPages(int delta)
```
    Update written pages in checkpoint;
    
    Parameters:
    
    delta - Pages num to update.
  - updateEvictedPages
```
void updateEvictedPages(int delta)
```
    Update evicted pages in checkpoint;
    
    Parameters:
    
    delta - Pages num to update.
  - clearCounters
```
void clearCounters()
```
    Clear cp progress counters.
  - onStateChanged
```
void onStateChanged(CheckpointState state,
                    Runnable clo)
```
    Invokes a callback closure then a checkpoint reaches specific state. The closure will not be called if an error has happened while transitting to the state.
    
    Parameters:
    
    state - State.
    
    clo - Closure to call.
