Examples of ReadOptions

org.apache.hadoop.io.ReadOptions
This class manages options which are passed while reading files.
org.iq80.leveldb.ReadOptions
org.rocksdb.ReadOptions
The class that controls the get behavior. Note that dispose() must be called before an Options instance become out-of-scope to release the allocated memory in c++.
