Constructor Detail

LimitedPipelineExecutor

public LimitedPipelineExecutor(int limit,
                               Adept2ThreadFactory threadFactory)

Deprecated.

Creates a new thread pool executor with the designated amount of pipelines and threads. The threads will stay idle for 60 seconds before they terminate.

Parameters:

limit - The maximum number of threads allowed in the pool and also the maximum number of pipelines.

threadFactory - The factory to use when the executor creates a new thread.

Method Detail

getPipelineFor

protected java.lang.Integer getPipelineFor(O object)

Deprecated.

Gets the identifier determining the pipeline for the designated object accordingly to the limit of the number of pipelines. Returns the hashcode of the designated object modulo the limit.

Specified by:

getPipelineFor in class AbstractPipeliningExecutor<O,java.lang.Integer>

Parameters:

object - The object for which to determine the pipeline.

Returns:

The identifier determining the pipeline for the designated object.
