Method Details

copy

public Channel copy()

Description copied from class: Channel

Create a copy of this instance. Mimics everything apart from the consumers. Also delimits already executed ExecutionTasks and those that are not executed yet. Be careful when revising this invariant.

Specified by:

copy in class Channel

createInstance

public ChannelInstance createInstance(Executor executor,
 OptimizationContext.OperatorContext producerOperatorContext,
 int producerOutputIndex)

Description copied from class: Channel

Create a ChannelInstance for this instance.

Specified by:

createInstance in class Channel

Parameters:

executor - that manages the resource or null if none
