getVersion

public long getVersion()

Description copied from interface: PersistentQueryHandle

Get the currently running version of the Persistent Query.

Specified by:

getVersion in interface PersistentQueryHandle

Returns:

the version of the running query

getState

public PersistentQueryState getState()

Description copied from interface: PersistentQueryHandle

Get the current state object for the Persistent Query.

Specified by:

getState in interface PersistentQueryHandle

Returns:

the current state

start

public void start()

Description copied from interface: PersistentQueryHandle

Start the worker.

Specified by:

start in interface PersistentQueryHandle

shutdown

public void shutdown(String lastAuthenticatedUser,
 String lastEffectiveUser)

Description copied from interface: PersistentQueryHandle

Shutdown the worker, if it is running.

Specified by:

shutdown in interface PersistentQueryHandle

Parameters:

lastAuthenticatedUser - the authenticating user requesting the shutdown

lastEffectiveUser - the effective user requesting the shuutdown

ensureShutdown

protected void ensureShutdown(boolean awaitDisconnection)

Parameters:

awaitDisconnection - Used to communicate whether we need to care further about ensuring disconnection, or not. If true, we block until interrupted or until another thread calls ensureShutdown(false). If false, we're asserting that the DB is already disconnected, or that we don't care (because no script was run yet).

checkQueryTerminatingOrTerminal

protected boolean checkQueryTerminatingOrTerminal()

maybeSetTerminalStatus

protected boolean maybeSetTerminalStatus(Supplier<PersistentQueryState.Status> statusSupplier)

onError

protected void onError(@Nullable
 Throwable t)

onFailure

protected void onFailure(@Nullable
 Throwable t,
 boolean awaitDisconnection)

onFailure

protected void onFailure(@Nullable
 Throwable t,
 boolean awaitDisconnection,
 @Nullable
 String message)

publishState

protected void publishState()

getScriptCode

protected String getScriptCode()
