Detailed Description

Base visitor class for AST traversal.

Implements the visitor pattern for traversing and processing AST nodes. Provides visit/leave hooks and tracks visited nodes to prevent infinite recursion.

Member Function Documentation

◆ _onWork()

void by::visitor::_onWork ( )
overrideprotectedvirtual

Implements by::worker< void, node >.

◆ _prepare()

void by::visitor::_prepare ( )
overrideprotectedvirtual

Reimplemented from by::worker< void, node >.

◆ setReturnable()

void by::visitor::setReturnable ( nbool  isReturnable)

if you set the visitor as returnable, nodes you have already been visited, will be visited again if it's refered by different nodes. in default, this value is false.
