Example 60 with DataOutputBuffer

use of org.apache.cassandra.io.util.DataOutputBuffer in project eiger by wlloyd.

the class CounterColumn method updateDigest.

/*
     * We have to special case digest creation for counter column because
     * we don't want to include the information about which shard of the
     * context is a delta or not, since this information differs from node to
     * node.
