parseDOMConfiguration()

std::optional< DOMConfig > parseDOMConfiguration

(

const std::string &

dom_configuration_line

)

Parse a line that should contain the ADF configuration for a single DOM.

Parameters

dom_configuration_line

the DOM configuration for a single DOM, which should be of the form :

DOMID N id_0 threshold_0 ... id_(N-1) threshold_(N-1) debug_write

where N is the number of (id,threshold) pairs to be found on the line (id = probe id, threshold = where to cut the signal)

write_to_debug_flag is an integer that indicate (if non zero) to write the acoustic data from this DOM should be written to a debug file

Returns

a DOMConfig object if the line is valid DOM configuration, otherwise std::nullopt
