Classes
struct	openswmm::perf::ScopedTimer

struct	openswmm::perf::GatedTimer

class	openswmm::perf::CounterBatch
	Private counters for one worker in a worksharing phase. Nested batches merge into the enclosing worker's batch. The outer batch merges under one lock after the loop; hydraulic arithmetic is unaffected. When profiling is disabled, no counters are initialized or merged. More...
