Enclosing class:

ZKUtil

public abstract static class ZKUtil.ZKUtilOp
extends Object

Represents an action taken by ZKUtil, e.g. createAndFailSilent. These actions are higher-level than ZKOp actions, which represent individual actions in the ZooKeeper API, like create.

Nested Class Summary

static class	ZKUtil.ZKUtilOp.CreateAndFailSilent ZKUtilOp representing createAndFailSilent in ZooKeeper (attempt to create node, ignore error if already exists)
static class	ZKUtil.ZKUtilOp.DeleteNodeFailSilent ZKUtilOp representing deleteNodeFailSilent in ZooKeeper (attempt to delete node, ignore error if node doesn't exist)
static class	ZKUtil.ZKUtilOp.SetData ZKUtilOp representing setData in ZooKeeper

Method Summary

static ZKUtil.ZKUtilOp	createAndFailSilent(String path, byte[] data)
static ZKUtil.ZKUtilOp	deleteNodeFailSilent(String path)
String	getPath()
static ZKUtil.ZKUtilOp	setData(String path, byte[] data)
