Member Function Documentation

dotString()

TCEString MIDDGEdge::dotString ( ) const

inlinevirtual

Returns the string that should be placed in the edge's properties section in the GraphViz Dot string.

This can be overridden in the derived class to add different properties (e.g., colors, etc.) to different type of edges. The default implementation only sets the label property.

Returns

String describing the Dot properties of the edge.

Reimplemented from GraphEdge.

Definition at line 106 of file MachineInstrDDG.hh.

                                { 
        return (boost::format("label=\"%d %s\"") % reg_ % typeAsString()).
            str();
    }

References reg_, and typeAsString().

Referenced by MachineInstrDDG::dotString().

Here is the call graph for this function:

toString()

TCEString MIDDGEdge::toString ( ) const

inlinevirtual

Return the label of the edge as a string.

Used for printing graph in GraphViz .dot file.

Returns

The edge ID as a string

Reimplemented from GraphEdge.
