  Sets the path that is used for the beacon handler. This is used to detect when the user has closed a tab.

  The beacon path can also be configured by setting the vaadin.ce.beaconPath system property either in the command line or with System.setProperty(String, String). If a system property is set, it will take precedence over this setting.

  Parameters:

  beaconPath - path used by the beacon handler

• setAutomaticallyActivatePush

  public void setAutomaticallyActivatePush(boolean automaticallyActivatePush)

  Sets whether server push should be automatically activated if needed. When enabled, which is the default, Collaboration Engine will automatically activate PushMode.AUTOMATIC if neither push nor polling is active for a UI where CollaborationEngine is used. When disabled, no automatic changes are made to the application's push configuration.

  Parameters:

  automaticallyActivatePush - true to automatically activate server push if needed, false to not make any automatic changes to the push configuration

  Since:

  3.0

• isAutomaticallyActivatePush

  public boolean isAutomaticallyActivatePush()

  Checks whether automatic push activation is enabled.

  Returns:

  true if automatic server push configuration is enabled, false if it's no enabled

  Since:

  3.0

  See Also:

  • setAutomaticallyActivatePush(boolean)

• setBackend

  public void setBackend(Backend backend)

  Sets the backend implementation to use. A backend can be used to distribute changes between multiple nodes in a cluster. By default, a local in-memory backend is used.

  This is currently an experimental feature and needs to be explicitly enabled using the Vaadin dev-mode Gizmo, in the experimental features tab, or by adding a src/main/resources/vaadin-featureflags.properties file with the following content: com.vaadin.experimental.collaborationEngineBackend=true

  Parameters:

  backend - the backend to use, not null

• getBackend

  public Backend getBackend()

  Gets the configured backend implementation.

  Returns:

  the backend implementation, not null

  See Also:

  • setBackend(Backend)

• getLicenseStorage

  public LicenseStorage getLicenseStorage()

  Gets the configured license-storage implementation.

  Returns:

  the license-storage implementation, or null if not configured

• setLicenseStorage

  public void setLicenseStorage(LicenseStorage licenseStorage)

  Sets a configured license-storage implementation.

  Parameters:

  licenseStorage - the license-storage implementation, or null to unset

• getExecutorService

  public ExecutorService getExecutorService()

  Gets the configured ExecutorService which will be used to dispatch actions asynchronously. A custom executor service can be configured with setExecutorService(ExecutorService).

  Returns:

  the configured executor service, or null if not set

• setExecutorService

  public void setExecutorService(ExecutorService executorService)

  Sets the ExecutorService which will be used to dispatch actions asynchronously. An executor service set with this method won't be shutdown automatically, so the developer should take care of that if needed. If not configured, Collaboration Engine will use a thread pool with a fixed number of threads equal to the number of available processors and will take care of shutting it down.

  Parameters:

  executorService - the executor service, or null to remove a previously configured one
