Namespaces
namespace	openswmm

namespace	openswmm::gage
	Rain records, accepted runoff-clock state and read-only report lookups. Context routines require aligned initialized gage/subcatchment arrays, valid project units and ordered finite table x/y pairs unless stated otherwise. State mutations are immediate; serialize updates with reads and use private copies for trials. Only precipitation splits convert rates to internal ft/s.

Functions
double	openswmm::gage::convertRainfall (double raw_value, GageState &state)
	Transform one raw rain record with standalone GageState factors.

PrecipSplit	openswmm::gage::splitPrecip (const SimulationContext &ctx, std::size_t sub)
	Split a subcatchment's current gage intensity into internal rain and snow.

void	openswmm::gage::updatePastRain (GageState &state, int time_step)
	Accumulate a standalone gage's held intensity into completed-hour history.

void	openswmm::gage::updatePastRain (SimulationContext &ctx, int time_step)
	Accumulate every gage's current held rate over one accepted runoff step.

double	openswmm::gage::getPastRain (const GageState &state, int hours)
	Sum completed hourly depth buckets, excluding the current partial hour.

const Table *	openswmm::gage::gageRainSeries (const SimulationContext &ctx, int gage_idx)
	Borrow the actual resolved source table for a gage.

int	openswmm::gage::gageSeriesRainType (const SimulationContext &ctx, int gage_idx)
	Select the transform appropriate to resolved source storage.

double	openswmm::gage::gageUnitsFactor (const SimulationContext &ctx, int gage_idx)
	Return the source-storage-to-project rainfall depth multiplier.

double	openswmm::gage::convertGageValue (double raw, int rain_type, double interval_sec, double &cumul_accum, double units_factor, double scale_factor)
	Transform one source record and apply units then scale factors.

bool	openswmm::gage::gageIsUsed (const SimulationContext &ctx, int gage_idx)
	Test whether the model or enabled rainfall mesh consumes a gage.

double	openswmm::gage::gageNextRainDate (const SimulationContext &ctx, int gage_idx, double t)
	Read the next runoff-clock rainfall boundary from cached gage state.

double	openswmm::gage::gageNextRateChange (const SimulationContext &ctx, int gage_idx, double date, double limit)
	Forecast the end of the current held rain rate without changing source state.

void	openswmm::gage::updateAllGages (SimulationContext &ctx, double current_time)
	Advance used gage record state and publish current effective rainfall.

double	openswmm::gage::getReportRainfall (const SimulationContext &ctx, int gage_idx, double report_date)
	Query rainfall using the most recently advanced runoff-gage state.

double	openswmm::gage::getReportRainfallFromSeries (const SimulationContext &ctx, int gage_idx, double report_date)
	Query report-time source records independently of a later runoff cursor.
