Class ProcedureStoreTracker.BitSetNode

java.lang.Object

org.apache.hadoop.hbase.procedure2.store.ProcedureStoreTracker.BitSetNode

Enclosing class:

ProcedureStoreTracker

public static class ProcedureStoreTracker.BitSetNode
extends Object

A bitmap which can grow/merge with other ProcedureStoreTracker.BitSetNode (if certain conditions are met). Boundaries of bitmap are aligned to multiples of BITS_PER_WORD. So the range of a ProcedureStoreTracker.BitSetNode is from [x * K, y * K) where x and y are integers, y > x and K is BITS_PER_WORD.
