Method Detail

threads

ExecControllerSpec.ComputeSpec threads(int threads)

Specify the number of threads for this group.

The default value for this parameter is 2 * Runtime.availableProcessors()

Specified by:

threads in interface ExecControllerSpec.EventLoopSpec

Parameters:

threads - the number of threads

Returns:

this

prefix

ExecControllerSpec.ComputeSpec prefix(String prefix)
