StoreFile (Apache HBase 2.5.0 API)

All Known Implementing Classes:

HStoreFile
```
@InterfaceAudience.LimitedPrivate(value="Coprocesssor")
 @InterfaceStability.Evolving
public interface StoreFile
```
An interface to describe a store data file.
NOTICE: this interface is mainly designed for coprocessor, so it will not expose all the internal APIs for a 'store file'. If you are implementing something inside HBase, i.e, not a coprocessor hook, usually you should use HStoreFile directly as it is the only implementation of this interface.

```
Optional<Cell> getFirstKey()
```
    Get the first key in this store file.
  - getLastKey
```
Optional<Cell> getLastKey()
```
    Get the last key in this store file.
  - getComparator
```
CellComparator getComparator()
```
    Get the comparator for comparing two cells.
  - getMaxMemStoreTS
```
long getMaxMemStoreTS()
```
    Get max of the MemstoreTS in the KV's in this store file.
  - getPath
```
org.apache.hadoop.fs.Path getPath()
```
    Returns Path or null if this StoreFile was made with a Stream.
  - getEncodedPath
```
org.apache.hadoop.fs.Path getEncodedPath()
```
    Returns Encoded Path if this StoreFile was made with a Stream.
  - getQualifiedPath
```
org.apache.hadoop.fs.Path getQualifiedPath()
```
    Returns Returns the qualified path of this StoreFile
  - isReference
```
boolean isReference()
```
    Returns True if this is a StoreFile Reference.
  - isHFile
```
boolean isHFile()
```
    Returns True if this is HFile.
  - isMajorCompactionResult
```
boolean isMajorCompactionResult()
```
    Returns True if this file was made by a major compaction.
  - excludeFromMinorCompaction
```
boolean excludeFromMinorCompaction()
```
    Returns True if this file should not be part of a minor compaction.
  - getMaxSequenceId
```
long getMaxSequenceId()
```
    Returns This files maximum edit sequence id.
  - getModificationTimeStamp
```
@Deprecated
long getModificationTimeStamp()
                                   throws IOException
```
    Deprecated. Since 2.0.0. Will be removed in 3.0.0.
    
    Get the modification time of this store file. Usually will access the file system so throws IOException.
    
    Throws:
    
    IOException
    
    See Also:
    
    getModificationTimestamp()
  - getModificationTimestamp
```
long getModificationTimestamp()
                       throws IOException
```
    Get the modification time of this store file. Usually will access the file system so throws IOException.
    
    Throws:
    
    IOException
  - isBulkLoadResult
```
boolean isBulkLoadResult()
```
    Check if this storefile was created by bulk load. When a hfile is bulk loaded into HBase, we append '_SeqId_<id-when-loaded>' to the hfile name, unless "hbase.mapreduce.bulkload.assign.sequenceNumbers" is explicitly turned off. If "hbase.mapreduce.bulkload.assign.sequenceNumbers" is turned off, fall back to BULKLOAD_TIME_KEY.
    
    Returns:
    
    true if this storefile was created by bulk load.
  - getBulkLoadTimestamp
```
OptionalLong getBulkLoadTimestamp()
```
    Return the timestamp at which this bulk load file was generated.
  - toStringDetailed
```
String toStringDetailed()
```
    Returns a length description of this StoreFile, suitable for debug output
  - getMinimumTimestamp
```
OptionalLong getMinimumTimestamp()
```
    Get the min timestamp of all the cells in the store file.
  - getMaximumTimestamp
```
OptionalLong getMaximumTimestamp()
```
    Get the max timestamp of all the cells in the store file.
