Method Detail

create

public java.lang.Object create(Token payload)

Description copied from interface: TreeAdaptor

Create a tree node from Token object; for CommonTree type trees, then the token just becomes the payload. This is the most common create call. Override if you want another kind of node to be built.

Specified by:

create in interface TreeAdaptor

Overrides:

create in class CommonTreeAdaptor

errorNode

public java.lang.Object errorNode(TokenStream input,
                                  Token start,
                                  Token stop,
                                  RecognitionException e)

Description copied from class: BaseTreeAdaptor

create tree node that holds the start and stop tokens associated with an error. If you specify your own kind of tree nodes, you will likely have to override this method. CommonTree returns Token.INVALID_TOKEN_TYPE if no token payload but you might have to set token type for diff node type. You don't have to subclass CommonErrorNode; you will likely need to subclass your own tree node class to avoid class cast exception.

Specified by:

errorNode in interface TreeAdaptor

Overrides:

errorNode in class BaseTreeAdaptor
