[docs] class ProfileTrans(PSyDataTrans): ''' Create a profile region around a list of statements. For example: >>> from psyclone.parse.algorithm import parse >>> from psyclone.parse.utils import ParseError >>> from psyclone.psyGen import PSyFactory, GenerationError >>> from psyclone.psyir.transformations import ProfileTrans >>> api = "gocean" >>> filename = "nemolite2d_alg.f90" >>> ast, invokeInfo = parse(filename, api=api, invoke_name="invoke") >>> psy = PSyFactory(api).create(invokeInfo) >>> >>> p_trans = ProfileTrans() >>> >>> schedule = psy.invokes.get('invoke_0').schedule >>> print(schedule.view()) >>> >>> # Enclose all children within a single profile region >>> p_trans.apply(schedule.children) >>> print(schedule.view()) This implementation relies completely on the base class PSyDataTrans for the actual work, it only adjusts the name etc, and the list of valid nodes.
