Detailed Description

Visitor for generating C for EBPF. This visitor is invoked on various subtrees.

Member Data Documentation

◆ asPointerVariables

std::set<cstring> P4::EBPF::CodeGenInspector::asPointerVariables

protected

asPointerVariables stores the list of string expressions that should be emitted as pointer variables.

◆ commentDescriptionDepth

int P4::EBPF::CodeGenInspector::commentDescriptionDepth = 0

protected

Since CodeGenInspector also generates C comments, this variable keeps track of the current comment depth.
