Interface ContextAware<V>

All Known Implementing Classes:

BaseActions, BaseParser, ListeningParser

public interface ContextAware<V>

Interface that can be implemented by classes containing action methods.

If a class implementing this interface is used in a parser, the generated parser will use this interface to inform the instance of the current context. This applies to Actions but also to parsers within parsers.

Note that implementing this interface currently will not prevent you from suffering the limits of actions; that is, if you are not the second or more member of a SequenceMatcher, you won't get a context (it will be null in this case).
