Constructor Details

AbstractOrchestration

public AbstractOrchestration(C taskExecutorService,
 Task<T> task)

Constructs a Task.Orchestration.

Parameters:

taskExecutorService - the TaskExecutorService that created the Task.Orchestration

task - the Task to be orchestrated

Method Details

concurrently

public Task.Orchestration<T> concurrently()

Description copied from interface: Task.Orchestration

Specify that the Task should be executed concurrently on its assigned Executors.

This is the default setting for execution.

Specified by:

concurrently in interface Task.Orchestration<T>

Returns:

the Task.Orchestration to permit fluent-style method chaining

sequentially

public Task.Orchestration<T> sequentially()

Description copied from interface: Task.Orchestration

Specify that the Task should be executed sequentially on its assigned Executors.

Specified by:

sequentially in interface Task.Orchestration<T>

Returns:

the Task.Orchestration to permit fluent-style method chaining

Description copied from interface: Task.Orchestration

Limit the Executors to only those that satisfy the specified Remote.Predicate.

Specified by:

filter in interface Task.Orchestration<T>

Parameters:

predicate - the TaskExecutorService.ExecutorInfo predicate

Returns:

the Task.Orchestration to permit fluent-style method chaining

limit

public Task.Orchestration<T> limit(int cLimit)

Description copied from interface: Task.Orchestration

Limit the number of Executors to use when executing the Task.

Specified by:

limit in interface Task.Orchestration<T>

Parameters:

cLimit - the number of Executors to use
