Constructor & Destructor Documentation

ScopedTimer() [1/2]

openswmm::perf::ScopedTimer::ScopedTimer ( double & a )

inlineexplicitnoexcept

Start an unconditional wall timer against a borrowed accumulator.

Reads the clock even when profiling is disabled. Nested ScopedTimers include child time, unlike GatedTimer. Do not copy; destruction must occur before a is destroyed.

Parameters

[in,out]

a

Caller-owned seconds accumulator that must outlive this timer; updates are not synchronized.

Here is the caller graph for this function:

~ScopedTimer()

openswmm::perf::ScopedTimer::~ScopedTimer ( )

inlinenoexcept

Add complete elapsed wall seconds to the borrowed accumulator.

No environment check and no locking; nested timer intervals can overlap.

ScopedTimer() [2/2]

openswmm::perf::ScopedTimer::ScopedTimer ( const ScopedTimer & )

delete

Prevent copying an active ScopedTimer scope.

A copied scope would duplicate ownership of timing/counter cleanup and is forbidden at compile time.

Here is the call graph for this function:

Member Function Documentation

operator=()

ScopedTimer & openswmm::perf::ScopedTimer::operator= ( const ScopedTimer & )

delete

Prevent replacing an active ScopedTimer scope by copy assignment.

Scope state must be completed by its original object on the thread that created it.
