HFileBlock	HFileReaderImpl.readBlock(long dataBlockOffset, long onDiskBlockSize, boolean cacheBlock, boolean pread, boolean isCompaction, boolean updateCacheMetrics, BlockType expectedBlockType, DataBlockEncoding expectedDataBlockEncoding)
HFileBlock	HFile.CachingBlockReader.readBlock(long offset, long onDiskBlockSize, boolean cacheBlock, boolean pread, boolean isCompaction, boolean updateCacheMetrics, BlockType expectedBlockType, DataBlockEncoding expectedDataBlockEncoding) Read in a file block.
protected HFileBlock	HFileReaderImpl.HFileScannerImpl.readNextDataBlock() Scans blocks in the "scanned" section of the HFile until the next data block is found.

参数类型为HFileBlock的org.apache.hadoop.hbase.io.hfile中的方法

限定符和类型	方法和说明
protected Cell	HFileReaderImpl.HFileScannerImpl.getFirstKeyCellInBlock(HFileBlock curBlock)
protected Cell	HFileReaderImpl.EncodedScanner.getFirstKeyCellInBlock(HFileBlock curBlock)
protected int	HFileReaderImpl.HFileScannerImpl.loadBlockAndSeekToKey(HFileBlock seekToBlock, Cell nextIndexedKey, boolean rewind, Cell key, boolean seekBefore)
protected int	HFileReaderImpl.EncodedScanner.loadBlockAndSeekToKey(HFileBlock seekToBlock, Cell nextIndexedKey, boolean rewind, Cell key, boolean seekBefore)
protected void	HFileReaderImpl.HFileScannerImpl.releaseIfNotCurBlock(HFileBlock block) The curBlock will be released by shipping or close method, so only need to consider releasing the block, which was read from HFile before and not referenced by curBlock.
void	HFileReaderImpl.returnBlock(HFileBlock block)
void	HFile.CachingBlockReader.returnBlock(HFileBlock block) Return the given block back to the cache, if it was obtained from cache.
protected void	HFileReaderImpl.HFileScannerImpl.updateCurrentBlock(HFileBlock newBlock) Updates the current block to be the given HFileBlock.
protected void	HFileReaderImpl.EncodedScanner.updateCurrentBlock(HFileBlock newBlock) Updates the current block to be the given HFileBlock.
