Examples of org.apache.hadoop.hbase.io.HalfHFileReader

org.apache.hadoop.hbase.io.HalfHFileReader
A facade for a {@link org.apache.hadoop.hbase.io.hfile.HFile.Reader} that serves upeither the top or bottom half of a HFile where 'bottom' is the first half of the file containing the keys that sort lowest and 'top' is the second half of the file with keys that sort greater than those of the bottom half. The top includes the split files midkey, of the key that follows if it does not exist in the file.
This type works in tandem with the {@link Reference} type. This classis used reading while Reference is used writing.
This file is not splitable. Calls to {@link #midkey()} return null.

          getBlockCache(), this.reference);
    } else {
      this.reader = new Reader(this.fs, this.path, getBlockCache(),
          this.inMemory);
