Class PrefixTreeBlockMeta

java.lang.Object
  extended by org.apache.hadoop.hbase.codec.prefixtree.PrefixTreeBlockMeta

@InterfaceAudience.Private
public class PrefixTreeBlockMeta
extends Object

Information about the block. Stored at the beginning of the byte[]. Contains things like minimum timestamp and width of FInts in the row tree. Most fields stored in VInts that get decoded on the first access of each new block.
