This class visits a structure of Nodes and generates appropriate code.
| CodeGeneratorErr (class) | CodeGeneratorErr |
This may occur for example, if an import policy has a dest part. The semantic check should however get rid of all errors.
| CodeGenerator (const VarMap& varmap, PolicyMap& pmap)
| CodeGenerator |
| CodeGenerator (const string& proto, const filter::Filter& filter,
const VarMap& varmap, PolicyMap& pmap)
| CodeGenerator |
Generate code for a specific protocol and filter [target]
This construct is mainly used by derived classes to set the code target.
Parameters:
| proto | target protocol. |
| filter | target filter type. |
| varmap | varmap. |
| CodeGenerator (const string& proto, const VarMap& varmap, PolicyMap& pmap)
| CodeGenerator |
Initialize code generation for an import of a specific protocol.
Parameters:
| proto | target protocol. |
| varmap | varmap. |
