Method Detail

fixForNamespace

public static java.lang.String fixForNamespace(java.lang.String namespace,
                               java.lang.String path)

Apply the namespace to the given path

Parameters:

namespace - namespace (can be null)

path - path

Returns:

adjusted path

getNodeFromPath

public static java.lang.String getNodeFromPath(java.lang.String path)

Given a full path, return the node name. i.e. "/one/two/three" will return "three"

Parameters:

path - the path

Returns:

the node

getPathAndNode

public static ZKPaths.PathAndNode getPathAndNode(java.lang.String path)

Given a full path, return the node name and its path. i.e. "/one/two/three" will return {"/one/two", "three"}

Parameters:

path - the path

Returns:

the node

mkdirs

public static void mkdirs(org.apache.zookeeper.ZooKeeper zookeeper,
          java.lang.String path)
                   throws java.lang.InterruptedException,
                          org.apache.zookeeper.KeeperException

Make sure all the nodes in the path are created. NOTE: Unlike File.mkdirs(), Zookeeper doesn't distinguish between directories and files. So, every node in the path is created. The data for each node is an empty blob

Parameters:

zookeeper - the client

path - path to ensure

Throws:

java.lang.InterruptedException - thread interruption

org.apache.zookeeper.KeeperException - Zookeeper errors

mkdirs

public static void mkdirs(org.apache.zookeeper.ZooKeeper zookeeper,
          java.lang.String path,
          boolean makeLastNode)
                   throws java.lang.InterruptedException,
                          org.apache.zookeeper.KeeperException

Make sure all the nodes in the path are created. NOTE: Unlike File.mkdirs(), Zookeeper doesn't distinguish between directories and files. So, every node in the path is created. The data for each node is an empty blob

Parameters:

zookeeper - the client

path - path to ensure

makeLastNode - if true, all nodes are created. If false, only the parent nodes are created

Throws:

java.lang.InterruptedException - thread interruption

org.apache.zookeeper.KeeperException - Zookeeper errors

getSortedChildren

public static java.util.List<java.lang.String> getSortedChildren(org.apache.zookeeper.ZooKeeper zookeeper,
                                                 java.lang.String path)
                                                          throws java.lang.InterruptedException,
                                                                 org.apache.zookeeper.KeeperException

Return the children of the given path sorted by sequence number

Parameters:

zookeeper - the client

path - the path

Returns:

sorted list of children

Throws:

java.lang.InterruptedException - thread interruption

org.apache.zookeeper.KeeperException - zookeeper errors

makePath

public static java.lang.String makePath(java.lang.String parent,
                        java.lang.String child)

Given a parent path and a child node, create a combined full path

Parameters:

parent - the parent

child - the child

Returns:

full path
