MemStoreFlusher.FlushRegionEntry (Apache HBase 1.2.12 API)

java.lang.Object
- org.apache.hadoop.hbase.regionserver.MemStoreFlusher.FlushRegionEntry

All Implemented Interfaces:

Comparable<Delayed>, Delayed, MemStoreFlusher.FlushQueueEntry

Enclosing class:

MemStoreFlusher
```
static class MemStoreFlusher.FlushRegionEntry
extends Object
implements MemStoreFlusher.FlushQueueEntry
```
Datastructure used in the flush queue. Holds region and retry count. Keeps tabs on how old this object is. Implements Delayed. On construction, the delay is zero. When added to a delay queue, we'll come out near immediately. Call requeue(long) passing delay in milliseconds before readding to delay queue if you want it to stay there a while.

MemStoreFlusher.FlushRegionEntry(Region r,
                                boolean forceFlushAllStores)
```
- Method Detail
  - isMaximumWait
```
public boolean isMaximumWait(long maximumWait)
```
    Parameters:
    maximumWait -
    
    Returns:
    True if we have been delayed > maximumWait milliseconds.
  - getRequeueCount
```
public int getRequeueCount()
```
    Returns:
    Count of times requeue(long) was called; i.e this is number of times we've been requeued.
  - isForceFlushAllStores
```
public boolean isForceFlushAllStores()
```
    Returns:
    whether we need to flush all stores.
  - requeue
```
public MemStoreFlusher.FlushRegionEntry requeue(long when)
```
    Parameters:
    when - When to expire, when to come up out of the queue. Specify in milliseconds. This method adds EnvironmentEdgeManager.currentTime() to whatever you pass.
    
    Returns:
    This.
