    This is a very small fork of lombok.ast as some Android tools needed a few modifications. The normal repository for lombok.ast is here https://github.com/rzwitserloot/lombok.ast and our changes for 0.2.3 are in this pull request: https://github.com/rzwitserloot/lombok.ast/pull/8

    The newest version!

/**
 * Implement this class and hand yourself to the {@link lombok.ast.Node#accept(AstVisitor)} method to get
 * a specific method called for each type of {@code Node}.
 * 
    
 * For each method, return {@code true} to indicate you've handled the type, and {@code false} to
 * indicate you haven't. The difference is: If you return {@code false} the children of the node
 * you didn't handle get passed to the implementation of this class instead.
 * 
    
 * If you return {@code false}, then after all children visit calls have been performed, the
 * {@link #endVisit(Node)} method is called to signal all children have been visited.
