bridges.symbol.Symbol Class Reference

Inheritance diagram for bridges.symbol.Symbol:

Detailed Description

This is an abstract class for deriving a number of Symbol shape objects, for use in a SymbolCollection.

Symbols correspond to a simplified subset of SVG paths and shapes for custom visual representations in BRIDGES.

Users will typically one of the subclasses of this object for creating shapes

Currently shapes supported are rectangle, circle, polygon, polyline and label; each shape has a name, location (x, y) and appropriate geometric and non-geometric attributes
