CompletionWrapper
class CompletionWrapper extends BaseTask implements WrappedTaskInterface (View source)
Creates a task wrapper that will manage rollback and collection management to a task when it runs. Tasks are automatically wrapped in a CompletionWrapper when added to a task collection.
Clients may need to wrap their task in a CompletionWrapper if it creates temporary objects.
Traits
Task input/output methods. TaskIO is 'used' in BaseTask, so any task that extends this class has access to all of the methods here.

Methods
Any class that uses ConfigAwareTrait SHOULD override this method , and define a prefix for its configuration items. This is usually done in a base class. When used, this method should return a string that ends with a "."; see BaseTask::configPrefix().
No description

Required verbosity level before any TaskIO output will be produced.
Print a message if the selected verbosity level is over this task's verbosity threshold.
Print information about a task in progress.
Provide notification that some part of the task succeeded.
Provide notification that there is something wrong, but execution can continue.
Provide notification that some operation in the task failed, and the task cannot continue.
Provide debugging notification. These messages are only displayed if the log level is VERBOSITY_DEBUG.
Get the formatted task name for use in task output.
Ask the provided parent class to inject all of the dependencies that it has and we need.
Take all dependencies availble to this task and inject any that are needed into the provided task. The general pattern is that, for every FooAwareInterface that this class implements, it should test to see if the child also implements the same interface, and if so, should call $child->setFoo($this->foo).
Create a CompletionWrapper.
No description
Before running this task, register its rollback and completion handlers on its collection. The reason this class exists is to defer registration of rollback and completion tasks until 'run()' time.
Make this wrapper object act like the class it wraps.

printTaskInfo(string $text, null|array $context = null)
Print information about a task in progress.
With the Symfony Console logger, NOTICE is displayed at VERBOSITY_VERBOSE and INFO is displayed at VERBOSITY_VERY_VERBOSE.
Robo overrides the default such that NOTICE is displayed at VERBOSITY_NORMAL and INFO is displayed at VERBOSITY_VERBOSE.
n.b. We should probably have printTaskNotice for our ordinary output, and use printTaskInfo for less interesting messages.
protected
printTaskSuccess(string $text, null|array $context = null)
Provide notification that some part of the task succeeded.
With the Symfony Console logger, success messages are remapped to NOTICE, and displayed in VERBOSITY_VERBOSE. When used with the Robo logger, success messages are displayed at VERBOSITY_NORMAL.
protected
printTaskWarning(string $text, null|array $context = null)
Provide notification that there is something wrong, but execution can continue.
Warning messages are displayed at VERBOSITY_NORMAL.
protected
printTaskError(string $text, null|array $context = null)
Provide notification that some operation in the task failed, and the task cannot continue.
Error messages are displayed at VERBOSITY_NORMAL.
protected
printTaskDebug($text, null|array $context = null)
Provide debugging notification. These messages are only displayed if the log level is VERBOSITY_DEBUG.

$this
inflect(InflectionInterface|mixed $parent)
Ask the provided parent class to inject all of the dependencies that it has and we need.
injectDependencies(mixed $child)
Take all dependencies availble to this task and inject any that are needed into the provided task. The general pattern is that, for every FooAwareInterface that this class implements, it should test to see if the child also implements the same interface, and if so, should call $child->setFoo($this->foo).
The benefits of this are pretty large. Any time an object that implements
InflectionInterface is created, just call $child->inflect($this), and
any available optional dependencies will be hooked up via setter injection.
The required dependencies of an object should be provided via constructor injection, not inflection.
__construct(Collection $collection, TaskInterface $task, TaskInterface $rollbackTask = null)
Create a CompletionWrapper.
Temporary tasks are always wrapped in a CompletionWrapper, as are any tasks that are added to a collection. If a temporary task is added to a collection, then it is first unwrapped from its CompletionWrapper (via its original() method), and then added to a new CompletionWrapper for the collection it is added to.
In this way, when the CompletionWrapper is finally executed, the task's rollback and completion handlers will be registered on whichever collection it was registered on.
