Uses of IndexInput in org.apache.lucene.codecs

Methods in org.apache.lucene.codecs with parameters of type IndexInput
`abstract void` `PostingsReaderBase.init(IndexInput termsIn)` Performs any initialization, such as reading and verifying the header from the provided terms dictionary `IndexInput`.
`protected int` `BlockTreeTermsReader.readHeader(IndexInput input)` Reads terms file header.
`protected int` `BlockTreeTermsReader.readIndexHeader(IndexInput input)` Reads index file header.
`protected abstract int` `MultiLevelSkipListReader.readSkipData(int level, IndexInput skipStream)` Subclasses must implement the actual skip data encoding in this method.
`abstract void` `PostingsReaderBase.readTermsBlock(IndexInput termsIn, FieldInfo fieldInfo, BlockTermState termState)` Reads data for all terms in the next block; this method should merely load the byte[] blob but not decode, which is done in `PostingsReaderBase.nextTerm(org.apache.lucene.index.FieldInfo, org.apache.lucene.codecs.BlockTermState)`.
`protected void` `BlockTreeTermsReader.seekDir(IndexInput input, long dirOffset)` Seek `input` to the directory offset.

Constructors in org.apache.lucene.codecs with parameters of type IndexInput
`MultiLevelSkipListReader(IndexInput skipStream, int maxSkipLevels, int skipInterval)` Creates a `MultiLevelSkipListReader`, where `skipInterval` and `skipMultiplier` are the same.
`MultiLevelSkipListReader(IndexInput skipStream, int maxSkipLevels, int skipInterval, int skipMultiplier)` Creates a `MultiLevelSkipListReader`.
