Methods in org.apache.hadoop.hbase.io.hfile that return HFileBlock

Modifier and Type	Method and Description
HFileBlock	HFileBlock.Writer.getBlockForCaching(CacheConfig cacheConf) Creates a new HFileBlock.
HFileBlock	BlockWithScanInfo.getHFileBlock()
HFileBlock	HFileBlock.BlockIterator.nextBlock() Get the next block, or null if there are no more blocks to iterate.
HFileBlock	HFileBlock.BlockIterator.nextBlockWithBlockType(BlockType blockType) Similar to HFileBlock.BlockIterator.nextBlock() but checks block type, throws an exception if incorrect, and returns the HFile block
HFileBlock	HFileReaderV2.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.
HFileBlock	HFileBlock.FSReader.readBlockData(long offset, long onDiskSize, int uncompressedSize, boolean pread) Reads the block at the given offset in the file with the given on-disk size and uncompressed size.
protected HFileBlock	HFileReaderV2.AbstractScannerV2.readNextDataBlock() Scans blocks in the "scanned" section of the HFile until the next data block is found.
HFileBlock	HFileBlockIndex.BlockIndexReader.seekToDataBlock(Cell key, HFileBlock currentBlock, boolean cacheBlocks, boolean pread, boolean isCompaction, DataBlockEncoding expectedDataBlockEncoding) Return the data block which contains this key.

void	HFileBlockIndex.BlockIndexReader.readMultiLevelIndexRoot(HFileBlock blk, int numEntries) Read the root-level metadata of a multi-level block index.
DataInputStream	HFileBlockIndex.BlockIndexReader.readRootIndex(HFileBlock blk, int numEntries) Read in the root-level index from the given input stream.
HFileBlock	HFileBlockIndex.BlockIndexReader.seekToDataBlock(Cell key, HFileBlock currentBlock, boolean cacheBlocks, boolean pread, boolean isCompaction, DataBlockEncoding expectedDataBlockEncoding) Return the data block which contains this key.
protected void	HFileReaderV2.ScannerV2.updateCurrBlock(HFileBlock newBlock) Updates the current block to be the given HFileBlock.
