org.apache.hadoop.hdfs.server.namenode.INode.QuotaDelta

Enclosing class:

INode

public static class INode.QuotaDelta
extends java.lang.Object

Information used to record quota usage delta. This data structure is usually passed along with an operation like INode.cleanSubtree(org.apache.hadoop.hdfs.server.namenode.INode.ReclaimContext, int, int). Note that after the operation the delta counts should be decremented from the ancestral directories' quota usage.
