Overview¶
This file contains 9 documented elements.
Functions¶
usage()¶
Prints the version information, usage message, and a help hint for the dottoxml command-line tool to standard output. The output includes the tool name and version (dottoxml 1.6, 2014-04-10, Dirk Baechle), the usage string defined in usgmsg, and a prompt directing the user to the -h or --help options for additional information. This function takes no parameters and returns no value.
exportDot(o, nodes, edges, options)¶
No description available.
Writes a DOT-format graph representation to the output stream o by opening a graph [ block and iterating over the provided nodes and edges collections. For each node in nodes, it delegates to the node's own exportDot method, passing o and options. For each edge in edges, it similarly delegates to the edge's exportDot method, passing o, nodes, and options.
Parameters:
- o
- nodes
- edges
- options
exportGML(o, nodes, edges, options)¶
No description available.
Writes a complete GML (Graph Modelling Language) graph representation to the provided output stream o. The function opens the graph block with fixed header attributes — including a comment, directed 1, and hierarchic 1 — then iterates over all entries in nodes and edges, delegating serialization to each element's own exportGML method. The graph block is closed with a terminating ]\n after all nodes and edges have been written.
Signature:
| Parameter | Description |
|---|---|
o |
A writable output stream to which the GML content is written. |
nodes |
A mapping of node identifiers to node objects, each exposing an exportGML method. |
edges |
An iterable of edge objects, each exposing an exportGML method. |
options |
Options passed through to each node's and edge's exportGML method (see implementation). |
Parameters:
- o
- nodes
- edges
- options
intes()¶
No description available.
Displays a modal text input dialog using QInputDialog, resized to 700×100 pixels, prompting the user to enter a heading ("intestazione") for a stratigraphic diagram. Returns the entered text as a string if the dialog interaction succeeds. Catches and prints any KeyError exception that occurs during execution.
reverse()¶
return true or false about the order epoch
exportGraphml(o, nodes, edges, options, ff)¶
Constructs and writes a complete GraphML document compatible with the yEd graph editor to the output stream o. The function builds a structured XML document containing a directed graph with a grouped table node representing stratigraphic periods as rows, populates it with the provided nodes and edges by delegating to their respective exportGraphml methods, and appends embedded SVG resources for custom node symbols. The output includes all required GraphML namespace declarations, key definitions, and yFiles-specific styling attributes.
Parameters:
- o
- nodes
- edges
- options
- ff
exportGDF(o, nodes, edges, options)¶
No description available.
Writes a GDF-formatted graph representation to the output object o, using the provided collections of nodes and edges. It begins by writing the node definition header "nodedef> name\n", then delegates serialization to each node's and edge's own exportGDF method, passing along the options parameter. The function concludes by writing the edge definition header "edgedef> node1,node2\n".
Parameters:
- o
- nodes
- edges
- options
main()¶
No description available. Entry point for the DOT graph conversion tool that parses command-line options and arguments to configure the output format (Graphml, GML, GDF, or DOT) and processing behavior (verbose output, node sweeping, label/color/arrow settings, and encoding overrides). It reads a DOT-format input file, parses its nodes and edges — including multiline definitions and default attribute inheritance — and writes the converted graph to the specified output file. If fewer than two positional arguments (input file and output file) are provided, it prints usage information and exits with a non-zero status code.
