ExtractDataFromFile()

std::map< std::string, std::vector< std::vector< uint8_t > > > ExtractDataFromFile

(

const std::string &

filename

)

User Function that reads data from input file and returns big data structure.

This function is only invoked once during Initialisation and returns a data structure that is a map with a key for each named publisher object / topic the map value is a vector of samples and each sample is a vector of bytes

If the map does not contain a key for a certain publisher object, the default behaviour is that the specific publisher object falls back to pattern generation mode.

Parameters

[in]

filename

pathname of the file to read, can also be used as a generic discriminator.

Returns

data structure containing data to publish

GetFitsColumn()

std::vector< std::vector< uint8_t > > GetFitsColumn	(	const std::string &	filename,
		const std::string &	colname )
