Class ScopeAndDeclarationFinder

  • All Implemented Interfaces:
    PLSQLParserVisitor
    public class ScopeAndDeclarationFinder
extends PLSQLParserVisitorAdapter
    Visitor for scope creation. Visits all nodes of an AST and creates scope objects for nodes representing syntactic entities which may contain declarations. For example, a block may contain variable definitions (which are declarations) and therefore needs a scope object where these declarations can be associated, whereas an expression can't contain declarations and therefore doesn't need a scope object. With the exception of global scopes, each scope object is linked to its parent scope, which is the scope object of the next embedding syntactic entity that has a scope.
