Classes¶

Node¶

a single node in the graph

Methods¶

init(self)¶

Initializes a new Node instance with default values for all instance attributes. Sets label to an empty string, id to 0, attribs to an empty dictionary, referenced to False, and sections to an empty list. This constructor takes no arguments beyond the implicit self reference.

initFromString(self, line)¶

extract node info from the given text line

getLabel(self, conf, multiline)¶

return the label of the node

getLabelWidth(self, conf, multiline)¶

return the maximum width label of the node label

complementAttributes(self, node)¶

from node copy all new attributes, that do not exist in self

exportDot(self, o, conf)¶

write the node in DOT format to the given file

exportGDF(self, o, conf)¶

write the node in GDF format to the given file

exportGML(self, o, conf)¶

write the node in GML format to the given file

exportGraphml(self, doc, parent, conf)¶

export the node in Graphml format and append it to the parent XML node

Edge¶

a single edge in the graph

Methods¶

init(self)¶

Initializes a new Edge instance with default values for all instance attributes. Sets id to 0, src and dest to empty strings, and attribs to an empty dictionary.

initFromString(self, line)¶

extract edge info from the given text line

getLabel(self, nodes, conf)¶

return the label of the edge

complementAttributes(self, edge)¶

from edge copy all new attributes, that do not exist in self

exportDot(self, o, nodes, conf)¶

write the edge in DOT format to the given file

exportGDF(self, o, nodes, conf)¶

write the edge in GDF format to the given file

exportGML(self, o, nodes, conf)¶

write the edge in GML format to the given file

exportGraphml(self, doc, parent, nodes, conf)¶

export the edge in Graphml format and append it to the parent XML node

Functions¶

compileAttributes(attribs)¶

return the list of attributes as a DOT text string

Parameters: - attribs

parseAttributes(attribs)¶

parse the attribute list and return a key/value dict for it

Parameters: - attribs

getLabelAttributes(label)¶

return the sections of the label attributes in a list structure

Parameters: - label

colorNameToRgb(fcol, defaultcol)¶

convert the color name fcol to an RGB string, if required

Parameters: - fcol - defaultcol

getColorAttribute(attribs, key, defaultcol, conf)¶

extract the color for the attribute key and convert it to RGB format if required

Parameters: - attribs - key - defaultcol - conf

escapeNewlines(label)¶

convert the newline escape sequences in the given label

Parameters: - label

findUnescapedQuote(string, spos, qchar)¶

Return the position of the next unescaped quote character in the given string, starting at the position spos. Returns a -1, if no occurrence was found.

Parameters: - string - spos - qchar

findUnquoted(string, char, spos, qchar)¶

Return the position of the next unquoted character char in the given string. Searching for the next position starts at spos, while parsing the quote characters is always done from the start of the string. Returns a -1, if no occurrence was found. Warning: Assumes that the user never searches for an actual quote char with this, but uses findUnescapedQuote instead (see above).

Parameters: - string - char - spos - qchar

findLastUnquoted(string, char, spos, qchar)¶

Return the position of the last unquoted character char in the given string. Searching for the last position starts at spos, while parsing the quote characters is always done from the start of the string. Returns a -1, if no occurrence was found. Warning: Assumes that the user never searches for an actual quote char with this, but uses findUnescapedQuote instead (see above).

Parameters: - string - char - spos - qchar
