Class DeploymentSynchronizer

java.lang.Object
  org.wso2.carbon.deployment.synchronizer.internal.DeploymentSynchronizer

public class DeploymentSynchronizer
extends Object

This class is responsible for maintaining a repository in the local file system in sync with a remote repository. The local repository could be an artifact repository used by Carbon, Axis2 or Synapse. In fact it could be any directory hierarchy in the local file system. The remote repository could be a registry instance, a version control system or an online data storage service. This implementation can commit the changes in the local file system to the remote repository, and checkout any updated artifacts from the repository to the local file system. Commit operations and checkout operations are synchronized so that both operations will never run at the same time. This implementation also supports triggering checkouts on events.

Method Detail

start

public void start()

Start this DeploymentSynchronizer instance. If the autoCommit and autoCheckout modes are not enabled, this method will do nothing. If such additional features are enabled, this method will schedule the necessary periodic tasks and get the auto-sync tasks up and running.

stop

public void stop()

commit

public boolean commit()
               throws DeploymentSynchronizerException

Commit the artifacts in the file system repository to the remote repository

Throws:

DeploymentSynchronizerException - If an error occurs while committing the artifacts

commit

public boolean commit(String filePath)
               throws DeploymentSynchronizerException

Commit the artifacts from the given path in the file system repository to the remote repository

Throws:

DeploymentSynchronizerException - If an error occurs while committing the artifacts

checkout

public boolean checkout()
                 throws DeploymentSynchronizerException

Checkout the artifacts stored in the repository to the file system. If the artifacts have already been checked out, an update will be executed instead.

Throws:

DeploymentSynchronizerException - If an error occurs while checking out or updating the resources

checkout

public boolean checkout(String filePath,
                        int depth)
                 throws DeploymentSynchronizerException

Checkout the artifacts stored in the repository to the file system. If the artifacts have already been checked out, an update will be executed instead.

Throws:

DeploymentSynchronizerException - If an error occurs while checking out or updating the resources

update

public boolean update(String rootPath,
                      String filePath,
                      int depth)
               throws DeploymentSynchronizerException

Checkout the artifacts stored in the repository to the file system. If the artifacts have already been checked out, an update will be executed instead.

Throws:

DeploymentSynchronizerException - If an error occurs while checking out or updating the resources

requestCheckout

public void requestCheckout(long timestamp)

Notify the synchronizer that a checkout needs to be performed. This method is mainly used in conjunction with the eventing mode of operation. Once this method is invoked, synchronizer will set a flag to indicate that a checkout needs to be performed. During the next execution of the synchronizer task, the checkout will be performed and the flag will be unset.

Parameters:

timestamp - A timestamp corresponding to the time of the notification

setAutoCommit

public void setAutoCommit(boolean autoCommit)

setAutoCheckout

public void setAutoCheckout(boolean autoCheckout)

setPeriod

public void setPeriod(long period)

setUseEventing

public void setUseEventing(boolean useEventing)

isUseEventing

public boolean isUseEventing()

isAutoCommit

public boolean isAutoCommit()

isAutoCheckout

public boolean isAutoCheckout()

getLastCheckoutTime

public long getLastCheckoutTime()

getLastCommitTime

public long getLastCommitTime()

getArtifactRepository

public ArtifactRepository getArtifactRepository()

doInitialSyncUp

public void doInitialSyncUp()
                     throws DeploymentSynchronizerException

Throws:

DeploymentSynchronizerException

syncGhostMetaArtifacts

public boolean syncGhostMetaArtifacts()
                               throws DeploymentSynchronizerException

Throws:

DeploymentSynchronizerException

sync

public void sync()
