Returns the state of this instance

Specified by:

getState in interface CuratorFramework

Returns:

state

isStarted

Description copied from interface: CuratorFramework

Return true if the client is started, not closed, etc.

Specified by:

isStarted in interface CuratorFramework

Returns:

true/false

start

public void start()

Description copied from interface: CuratorFramework

Start the client. Most mutator methods will not work until the client is started

start in interface CuratorFramework

close

public void close()

Description copied from interface: CuratorFramework

Stop the client

Specified by:

close in interface Closeable

Specified by:

close in interface AutoCloseable

Specified by:

close in interface CuratorFramework

nonNamespaceView

public CuratorFramework nonNamespaceView()

Description copied from interface: CuratorFramework

Returns a facade of the current instance that does _not_ automatically pre-pend the namespace to all paths

Specified by:

nonNamespaceView in interface CuratorFramework

Returns:

facade

getNamespace

public String getNamespace()

Description copied from interface: CuratorFramework

Return the current namespace or "" if none

Specified by:

getNamespace in interface CuratorFramework

Returns:

namespace

usingNamespace

public CuratorFramework usingNamespace(String newNamespace)

Description copied from interface: CuratorFramework

Returns a facade of the current instance that uses the specified namespace or no namespace if newNamespace is null.

Specified by:

usingNamespace in interface CuratorFramework

Parameters:

newNamespace - the new namespace or null for none

Returns:

facade

create

public CreateBuilder create()

Description copied from interface: CuratorFramework

Start a create builder

Specified by:

create in interface CuratorFramework

Returns:

builder object

delete

public DeleteBuilder delete()

Description copied from interface: CuratorFramework

Start a delete builder

Specified by:

delete in interface CuratorFramework

Returns:

builder object

checkExists

public ExistsBuilder checkExists()

Description copied from interface: CuratorFramework

Start a get ACL builder

Specified by:

getACL in interface CuratorFramework

Returns:

builder object

setACL

public SetACLBuilder setACL()

Description copied from interface: CuratorFramework

Start a set ACL builder

Specified by:

setACL in interface CuratorFramework

Returns:

builder object

inTransaction

public CuratorTransaction inTransaction()

Specified by:

getConnectionStateListenable in interface CuratorFramework

Returns:

listenable

getCuratorListenable

public Listenable<CuratorListener> getCuratorListenable()

Description copied from interface: CuratorFramework

Returns the listenable interface for events

Specified by:

getCuratorListenable in interface CuratorFramework

Returns:

listenable

getUnhandledErrorListenable

public Listenable<UnhandledErrorListener> getUnhandledErrorListenable()

Description copied from interface: CuratorFramework

Returns the listenable interface for unhandled errors

Specified by:
