public interface PersistTask<A,T>
Implemented by users. Tasks should be stateless.

  • Method Details

    • run

      @Nullable T run(Optional<A> a, CommandContext commandContext) throws Exception
      Throws:
      Exception

    • unwrap

      default List<PersistTask> unwrap()
      If this task is composed of inner tasks, you must give access to the inner tasks by overriding this method.
      Returns:
      all inner tasks.

    • compose

      default <B> PersistTask<A,B> compose(PersistTask<T,B> task)
      Creates a task that is the composition of this and task. That means task is executed with the result of this as its argument.

    • compose2

      default <B> PersistTaskIterable<A,B> compose2(PersistTask<T, Iterable<B>> task)
      Executes the given a task that returns a list with the result of this task. This returns a PersistTaskIterable for convenience.

    • andThenDo

      default PersistTask<A,Void> andThenDo(PersistTask<A,?> next)
      Executes this task and then the given one, discarding any results.

    • discardResult

      default PersistTask<A,Void> discardResult()
      Return a new task that runs this task and discards the result. This task is executed with CollectMode.NONE.

    • orWhen

      default PersistTask<A,T> orWhen(PersistTask<T,Boolean> predicate, PersistTask<A,T> other)
      Run the `other` task if the result of this task fulfills the `predicate`. The 'other' task will be executed using the initial argument.

    • composeWhen

      default PersistTask<A,T> composeWhen(PersistTask<T,Boolean> predicate, PersistTask<T,T> other)
      Run the 'other' task if the result of this task fulfills the 'predicate'. The 'other' task will use the result of the current task as argument.

    • orWhenNot

      default PersistTask<A,T> orWhenNot(PersistTask<T,Boolean> predicate, PersistTask<A,T> other)
      Run the `other` task if the result of this task does not fulfill the predicate.

    • passWhen

      default PersistTask<A,T> passWhen(PersistTask<T,Boolean> predicate)
      Pass the result of this task only if it fulfills the `predicate`.

    • passWhenNot

      default PersistTask<A,T> passWhenNot(PersistTask<T,Boolean> predicate)
      Pass the result of this task only if it does not fulfill the `predicate`.

    • ifElse

      default <V> PersistTask<A,V> ifElse(PersistTask<T,Boolean> predicate, PersistTask<T,V> ifBranch, PersistTask<T,V> elseBranch)
      representation of a basic if-else construct as a task executes the ifBranch if the predicate is true, otherwise executes the elseBranch
      Parameters:
      predicate - the predicate task
      ifBranch - the if task
      elseBranch - the else task

    • expand

      default PersistTaskIterable<Iterable<A>, T> expand(CollectMode collectMode)
      Wraps this task in a task that accepts a list of arguments applying those in order to this task and returns the collected results in a list. How the results are collected is defined by CollectMode.

    • expand

      default PersistTaskIterable<Iterable<A>, T> expand()
      Wraps this task in a task that accepts a list of arguments applying those in order to this task and returns the collected results in a list. The results are collected according to the value of CollectMode which is obtained from the current mode via key Keys.COLLECTMODE. If no such key is present, it defaults to CollectMode.ALL.

    • skipErrors

      default PersistTask<A,T> skipErrors(org.slf4j.Logger log)
      Return a task that catches all Exceptions when running this task to *not* propagate them. They are logged only. This can be useful when doing batch processing to skip erroneous input (and not let the whole task fail).
      Parameters:
      log - the logger used to log the exception (level ERROR)

    • getDescription

      @Nullable default @Nullable String getDescription()
      Returns:
      an optional plain-text description of this task
