Classes that implement the [visitor pattern] for traversing the Sass [AST].
|
||
|
|
Callers can either implement interfaces like [`StatementVisitor`] from scratch
|
||
|
|
to handle *all* Sass node types, or extend helper classes like
|
||
|
|
[`RecursiveStatementVisitor`] which traverse the entire AST to handle only
|
||
|
|
specific nodes.
