GraphViz layout

Layout for Roassal using GraphViz.

Example

someClasses := RTAbstractLine withAllSubclasses.
allMethodCategories := (someClasses flatCollect: #protocols) asSet asArray.
b := RTUMLClassBuilder new.
b lineShape line.
b lineShape color: Color black.
n := RTMultiLinearColorForIdentity new objects: allMethodCategories.
b methodShape color: [ :m | n rtValue: m protocol ].
b methodsNames: [ :cls | cls rtmethods sortedAs: #protocol ].
b addObjects: someClasses.

b layout graphVizDot.

b.

See class-side of RTGraphVizLayout for more examples.

RTGraphVizLayout new
	timeout: aNumberOfSeconds;
	orthogonalLines;
	on: elements directed: directedEdges undirected: undirectedEdges

• timeout - large and complex graphs may take dot long time to process; you can cap it (default 10 seconds)

• orthogonalLines - draw lines orthogonally

• elements - nodes that should be positioned; their size will be fixed (dot won't change their size)

• directedEdges - edges that should adhere to the same dot ordering direction (e.g.: top->bottom)

• undirectedEdges - edges whose direction is not relevant
