gedInput tells which input data is required by a
given, or all GED algorithm(s).
Similarly gedOutput tells the type of output
returned by each ged algorithm.
gedIO combines the information about input data
and ouput data in a compact way.
isRequired, onlyRequired and
anyRequired return a single logical if x is
not missing, or a logical vector with one element per
registered algorithm otherwise.
onlyRequired tells if a given input data is the
only required data for a GED algorithm to run.
anyRequired tells if any input data is required at
all to run a GED algorithm.
gedInput(x) gedOutput(x) gedIO(x = gedAlgorithm()) isRequired(type, x) onlyRequired(type, x) anyRequired(x)
GEDalgorithm object, an access key, a registry
entry, etc..'Basis', 'Coef' or
'Marker'.If x is not missing gedInput returns a
logical vector with one element per type of possible
input: 'Basis', 'Coef', 'Marker'. If
x is missing, then it returns a matrix of these
vectors, with one row per algorithm registered in the
internal registry.
