Package org.eclipse.steady.goals

Class AbstractGoal

java.lang.Object

org.eclipse.steady.goals.AbstractGoal

All Implemented Interfaces:

Runnable

Direct Known Subclasses:

AbstractAppGoal, AbstractSpaceGoal

public abstract class AbstractGoal
extends Object
implements Runnable

Represents the execution of a goal, which is triggered by client components such as the CLI and the Maven plugin. There exist different types of goals, e.g., GoalType.CLEAN or GoalType.A2C. Goal executions can be started and stopped manually using the methods start(), stop(), stop(Exception) and upload(boolean). Goal executions can also be executed automatically using the methods executeSync() or executeAsync(), which results in the sequential execution of the above-mentioned methods start(), etc. Subclasses typically override the methods prepareExecution, executeTasks and cleanAfterExecution. See VULAS-204 in case we run into problems related to special characters in paths.

AbstractGoal

protected AbstractGoal(GoalType _goal,
                       boolean _monitor_mem)

Constructor for AbstractGoal.

Parameters:

_goal - a GoalType object.

_monitor_mem - a boolean.

Method Detail

getId

public String getId()

Getter for the field id.

Returns:

a String object.

setObserver

public void setObserver(ExecutionObserver observer)

Setter for the field observer.

Parameters:

observer - a ExecutionObserver object.

getGoalType

public GoalType getGoalType()

Getter for the field goalType.

Returns:

a GoalType object.

getGoalClient

public GoalClient getGoalClient()

getGoalClient.

Returns:

a GoalClient object.

setGoalClient

public void setGoalClient(GoalClient _client)

setGoalClient.

Parameters:

_client - a GoalClient object.

runsIn

public boolean runsIn(GoalClient _client)

Returns true if this AbstractGoal is executed in the given GoalClient, false otherwise.

Parameters:

_client - a GoalClient object.

Returns:

a boolean.

executeAsync

public final void executeAsync()

executeAsync.

run

public final void run()

run.

Specified by:

run in interface Runnable

executeSync

public final void executeSync()
                       throws GoalConfigurationException,
                              GoalExecutionException

executeSync.

Throws:

GoalConfigurationException - if any.

GoalExecutionException - if any.

getConfiguration

protected final VulasConfiguration getConfiguration()

Returns the configuration of this goal execution. If the configuration has not been set before, a new instance of VulasConfiguration is created and returned. As such, the configuration settings of different goal executions can be isolated.

Returns:

a VulasConfiguration object.

setConfiguration

public final AbstractGoal setConfiguration(VulasConfiguration _c)

Setter for the field configuration.

Parameters:

_c - a VulasConfiguration object.

Returns:

a AbstractGoal object.

getGoalContext

public final GoalContext getGoalContext()

Returns the context of this goal execution. If the context has not been set before, it is constructed by reading tenant, space and app information from the configuration obtained from getConfiguration().

Returns:

a GoalContext object.

setGoalContext

public final void setGoalContext(GoalContext _ctx)

Setter for the field goalContext.

Parameters:

_ctx - a GoalContext object.

prepareExecution
