Pangraph.Gml.Parser

Description

Functions for parseing gml (Graphical Modelling Language) files. A gml specification can be found at: http://www.fim.uni-passau.de/fileadmin/files/lehrstuhl/brandenburg/projekte/gml/gml-technical-report.pdf.

This follows the specification except for two cases:

All files are assumed to be encoded in UTF8
The line length limit is ignored.

Synopsis

parse :: ByteString -> Maybe Pangraph
parseGml :: ByteString -> Maybe (Gml Text)
decode :: Gml Text -> Gml Text
gmlToPangraph :: Gml Text -> Maybe Pangraph

Documentation

parse :: ByteString -> Maybe Pangraph Source #

Parses the ByteString into a Pangraph.

parseGml :: ByteString -> Maybe (Gml Text) Source #

Parses the ByteString into a Gml ast. The function doesn't decode special characters inside strings. To decode special characters inside strings use the decode function.

decode :: Gml Text -> Gml Text Source #

Decodes special characters inside gml strings.

gmlToPangraph :: Gml Text -> Maybe Pangraph Source #

Converts a gml ast into a Pangraph. If a node/edge contains a gml object these object are not contained in the resulting Pangraph.
