public static final DeclarationVisitor NO_OP

A visitor that has no side effects and keeps no state.

Method Detail

getDeclarationScanner

public static DeclarationVisitor getDeclarationScanner(DeclarationVisitor pre,
                                                       DeclarationVisitor post)

Return a DeclarationVisitor that will scan the declaration structure, visiting declarations contained in another declaration. For example, when visiting a class, the fields, methods, constructors, etc. of the class are also visited. The order in which the contained declarations are scanned is not specified.

The pre and post DeclarationVisitor parameters specify, respectively, the processing the scanner will do before or after visiting the contained declarations. If only one of pre and post processing is needed, use DeclarationVisitors.NO_OP for the other parameter.

Parameters:

pre - visitor representing processing to do before visiting contained declarations.

post - visitor representing processing to do after visiting contained declarations.

getSourceOrderDeclarationScanner

public static DeclarationVisitor getSourceOrderDeclarationScanner(DeclarationVisitor pre,
                                                                  DeclarationVisitor post)

Return a DeclarationVisitor that will scan the declaration structure, visiting declarations contained in another declaration in source code order. For example, when visiting a class, the fields, methods, constructors, etc. of the class are also visited. The order in which the contained declarations are visited is as close to source code order as possible; declaration mirrors created from class files instead of source code will not have source position information.

The pre and post DeclarationVisitor parameters specify, respectively, the processing the scanner will do before or after visiting the contained declarations. If only one of pre and post processing is needed, use DeclarationVisitors.NO_OP for the other parameter.

Parameters:

pre - visitor representing processing to do before visiting contained declarations.

post - visitor representing processing to do after visiting contained declarations.
