Class
RailroadDiagramBlock
ChartForgeX.VisualBlocks
A generic grammar diagram with symbolic references and native recursive railroad geometry.
Inheritance
- VisualBlock<RailroadDiagramBlock>
- RailroadDiagramBlock
Remarks
Native layout accepts up to 512 rules, 32768 expression occurrences and 128 nesting levels. References and repetition counts remain symbolic. Measure or call WithNaturalSize after changing rules, padding or typography; a smaller explicit frame is rejected instead of clipping grammar.
