```
  - removeTable
```
public void removeTable(MVTable table)
```
    Remove a table.
    
    参数:
    
    table - the table
  - flush
```
public void flush()
```
    Store all pending changes.
  - closeImmediately
```
public void closeImmediately()
```
    Close the store, without persisting changes.
  - initTransactions
```
public void initTransactions()
```
    Commit all transactions that are in the committing state, and rollback all open transactions.
  - removeTemporaryMaps
```
public void removeTemporaryMaps(BitField objectIds)
```
    Remove all temporary maps.
    
    参数:
    
    objectIds - the ids of the objects to keep
  - nextTemporaryMapName
```
public String nextTemporaryMapName()
```
    Get the name of the next available temporary map.
    
    返回:
    
    the map name
  - prepareCommit
```
public void prepareCommit(Session session,
                          String transactionName)
```
    Prepare a transaction.
    
    参数:
    
    session - the session
    
    transactionName - the transaction name (may be null)
  - getInDoubtTransactions
```
public ArrayList<InDoubtTransaction> getInDoubtTransactions()
```
  - setCacheSize
```
public void setCacheSize(int kb)
```
    Set the maximum memory to be used by the cache.
    
    参数:
    
    kb - the maximum size in KB
  - getInputStream
```
public InputStream getInputStream()
```
  - sync
```
public void sync()
```
    Force the changes to disk.
  - compactFile
```
public void compactFile(long maxCompactTime)
```
    Compact the database file, that is, compact blocks that have a low fill rate, and move chunks next to each other. This will typically shrink the database file. Changes are flushed to the file, and old chunks are overwritten.
    
    参数:
    
    maxCompactTime - the maximum time in milliseconds to compact
  - close
```
public void close(long maxCompactTime)
```
    Close the store. Pending changes are persisted. Chunks with a low fill rate are compacted, but old chunks are kept for some time, so most likely the database file will not shrink.
    
    参数:
    
    maxCompactTime - the maximum time in milliseconds to compact
  - statisticsStart
```
public void statisticsStart()
```
    Start collecting statistics.
  - statisticsEnd
```
public Map<String,Integer> statisticsEnd()
```
    Stop collecting statistics.
    
    返回:
    
    the statistics
