Function Documentation

template<typename ValueType>

ValueType Psana::EpicsLib::getEpicsValue	(	const Epics::EpicsPvHeader &	pv,
		int	index
	)

Function which extracts value from EPICS PV and converts it to requested type.

Exceptions:

	boost::numeric::bad_numeric_cast	in case of overflows
	boost::bad_lexical_cast	if string vale cannot be converted to number
	std::invalid_argument	if PV has unexpected type
