Method Detail

execute

public <T> T execute(CommandCallback<T> callback)

Description copied from interface: ProcessManager

Execute a user command within a "transaction". This method blocks until ProcessManagerStatus.AVAILABLE.

This method may throw RuntimeExceptions that occurred while executing.

Specified by:

execute in interface ProcessManager

Type Parameters:

T - the class of the object that CommandCallback.callback() will return (required)

Parameters:

callback - the callback to actually executed (required)

Returns:

the result of executing the callback

getLastScanDuration

public long getLastScanDuration()

Specified by:

getLastScanDuration in interface ProcessManager

Returns:

how many milliseconds the last scan execution took to complete (0 = never ran; >0 = last execution time)

getMinimumDelayBetweenScan

public long getMinimumDelayBetweenScan()

Specified by:

getMinimumDelayBetweenScan in interface ProcessManager

Returns:

how many milliseconds must pass between each scan (0 = manual only; <0 = auto-scaled; >0 = interval)

isDevelopmentMode

public boolean isDevelopmentMode()

Specified by:

isDevelopmentMode in interface ProcessManager

Returns:

true if the system is in development mode, which generally means more detailed diagnostics are requested from add-ons (defaults to false)

setDevelopmentMode

public void setDevelopmentMode(boolean developmentMode)

Specified by:

setDevelopmentMode in interface ProcessManager

setMinimumDelayBetweenScan

public void setMinimumDelayBetweenScan(long minimumDelayBetweenScan)

Specified by:

setMinimumDelayBetweenScan in interface ProcessManager

Parameters:

minimumDelayBetweenScan - how many milliseconds must pass between each scan

terminate

public void terminate()

Description copied from interface: ProcessManager

Allows the process manager to terminate gracefully. In particular this means any background threads it has started are terminated. It is safe to call this method more than once, but no other method in the process manager need operate correctly after termination.

Specified by:

terminate in interface ProcessManager

timerBasedScan

public void timerBasedScan()

Specified by:

timerBasedScan in interface ProcessManager

activate

protected void activate(org.osgi.service.component.ComponentContext context)

deactivate

protected void deactivate(org.osgi.service.component.ComponentContext context)

getFileMonitorService

public org.springframework.roo.file.monitor.FileMonitorService getFileMonitorService()

getStartLevel

public org.osgi.service.startlevel.StartLevel getStartLevel()

getUndoManager

public org.springframework.roo.file.undo.UndoManager getUndoManager()
