@Inject
public ReadRange(com.datastax.oss.driver.api.core.CqlSession session,
                         @BinaryReadConsistency
                         com.datastax.oss.driver.api.core.ConsistencyLevel consistency)

Parameters:

session - the cassandra session

consistency - the consistency level

id - the IRI of a binary to read

first - which byte to begin reading on

last - which byte to end reading on

Returns:

An InputStream of bytes as requested. The skip method of this InputStream is guaranteed to skip as many bytes as asked.
