Modifier and Type	Method	Description
static long	CodecUtil.checksumEntireFile(IndexInput input)	Clones the provided input, reads all bytes from the file, and calls CodecUtil.checkFooter(org.apache.lucene.store.ChecksumIndexInput)
abstract void	PostingsReaderBase.init(IndexInput termsIn, SegmentReadState state)	Performs any initialization, such as reading and verifying the header from the provided terms dictionary IndexInput.
static byte[]	CodecUtil.readFooter(IndexInput in)	Retrieves the full footer from the provided IndexInput.
static byte[]	CodecUtil.readIndexHeader(IndexInput in)	Retrieves the full index header from the provided IndexInput.
protected abstract int	MultiLevelSkipListReader.readSkipData(int level, IndexInput skipStream)	Subclasses must implement the actual skip data encoding in this method.
static long	CodecUtil.retrieveChecksum(IndexInput in)	Returns (but does not validate) the checksum previously written by CodecUtil.checkFooter(org.apache.lucene.store.ChecksumIndexInput).
static void	CodecUtil.verifyAndCopyIndexHeader(IndexInput in, DataOutput out, byte[] expectedID)	Expert: verifies the incoming IndexInput has an index header and that its segment ID matches the expected one, and then copies that index header into the provided DataOutput.
