Description

Metrics regarding the structure and complexity of Sdf grammars.

Synopsis

data StructMetrics = StructMetrics { timp :: Float lev :: Int clev :: Float nslev :: Int dep :: Int hei :: Int } calcStructMetrics :: SDF -> StructMetrics structMetrics :: StructMetrics -> GroupMetric

Defined data structures

data StructMetrics

Record which holds all structural metrics Constructors StructMetrics timp :: Float Tree Impurity lev :: Int Count of levels (LEV) clev :: Float Normalized count of levels (CLEV) nslev :: Int Number of non-singleton levels (NSLEV) dep :: Int Size of largest level (DEP) hei :: Int Maximum height of the graph (HEI)

Metric calculation functions

calcStructMetrics :: SDF -> StructMetrics

Calculate structural metrics

structMetrics :: StructMetrics -> GroupMetric

Creates a uniform representation of the metrics converting the internal StructMetrics record to a GroupMetric type which holds not only all the calculated metric values but also all information about the metrics: description and name.
