mrs_string obsNamesAddPrefix	(	mrs_string	observationNames,
		mrs_string	prefix
	)

Helper function for adding a prefix to each of the observation names.

Parameters:

	observationNames	string of observation names (comma separated)
	prefix	the prefix the prepend to all the observation names.

Returns:

new comma separated observation name string

Note:

Comma separated observation names in Marsyas use/expect a trailing comma after the last item, this function follows this convention.

Todo:

Use this function in more places (e.g. search for occurrences of 'find(",")').

std::vector< mrs_string > obsNamesSplit

(

mrs_string

observationNames

)

Helper function for splitting an observation names string used in MarSystems.

Helper function for splitting an observation name string.

Parameters:

observationNames,:

the observation names string to split.

Returns:

a vector of strings.

Like Marsyas::stringSplit(), but taking the Marsyas convention of a trailing comma into account: the last comma does not produce an empty item. For example, the observation name string "foo,bar," will produce the items "foo" and "bar".

Todo:

Use this function in more places (e.g. search for occurrences of 'find(",")').

References Marsyas::stringSplit().

std::vector< mrs_string > stringSplit	(	mrs_string	input,
		mrs_string	delimiter
	)

Helper function for splitting a string.

Parameters:

	input	the string to split.
	delimiter	the string to split on.

Returns:

a vector of strings.

Marsyas::obsNamesSplit()

Note:

Comma separated observation names in Marsyas use/expect a trailing comma after the last item. Splitting this string in the traditional way, results in an empty string at the end of the list. Use Marsyas::obsNamesSplit() to avoid this.

Todo:

Use this function in more places (e.g. search for occurrences of 'find(",")').
