List of readDirect() Examples

Examples of readDirect()

org.apache.cassandra.io.IFileReader.readDirect()
Be extremely careful while using this API. This currently used to read the commit log header from the commit logs. Treat this as an internal API. @param bytes read into this byte array.

Examples of org.apache.cassandra.io.IFileReader.readDirect()

    void readCommitLogHeader(String logFile, byte[] bytes) throws IOException
    {
        IFileReader logReader = SequenceFile.reader(logFile);
        try
        {
            logReader.readDirect(bytes);
        }
        finally
        {
            logReader.close();
        }
