Parameters:

acceptIncompleteList - When set to false, this method throws an UnsolvedSymbolException if one or more ancestor could not be resolved.

toAst

public java.util.Optional<Node> toAst()

Description copied from interface: AssociableToAST

If the declaration is associated to an AST node return it, otherwise it return empty. Declaration based on source code have an AST node associated while others don't. Example of other declarations are declarations coming from reflection or JARs. You may wonder how this method is different from the various getWrappedNode. The difference is that toAst is present in all Resolved* declarations (such as ResolvedAnnotationDeclaration), while getWrappedNode is present only on the subclasses of the Resolved* declarations that derive from JP AST nodes (such as JavaParserClassDeclaration). Therefore one which has a Resolved* declaration need to do a downcast before being able to use getWrappedNode. Now, this means that toAst could potentially replace getWrappedNode (but not the other way around!). However toAst return an Optional, which is less convenient than getting the direct node. Also, toAst sometimes have to return a more generic node. This is the case for subclasses of ResolvedClassDeclaration. In those cases toAst return a Node. Why? Because both anonymous class declarations and standard class declarations are subclasses of that. In one case the underlying AST node is an ObjectCreationExpr, while in the other case it is ClassOrInterfaceDeclaration. In these cases getWrappedNode is particularly nice because it returns the right type of AST node, not just a Node.
