If <code>true</code> is returned, the given node's child nodes will be * visited next; however, if <code>false</code> is returned, the given node's child nodes will not * be visited. The default implementation provided by this class does nothing and returns * <code>true</code> (with the exception of {@link #visit(Javadoc) ASTVisitor.visit(Javadoc)}). * Subclasses may reimplement this method as needed.</li> * <li><code>public void endVisit(<i>T</i> node)</code> - Visits the given node to perform some * arbitrary operation. When used in the conventional way, this method is called after all of the * given node's children have been visited (or immediately, if <code>visit</code> returned * <code>false</code>). The default implementation provided by this class does nothing. Subclasses * may reimplement this method as needed.</li> * </ul> * </p> * In addition, there are a pair of methods for visiting AST nodes in the abstract, regardless of * node type: * <ul> * <li><code>public void preVisit(ASTNode node)</code> - Visits the given node to perform some * arbitrary operation. This method is invoked prior to the appropriate type-specific * <code>visit</code> method. The default implementation of this method does nothing. Subclasses may * reimplement this method as needed.</li> * <li><code>public void postVisit(ASTNode node)</code> - Visits the given node to perform some * arbitrary operation. This method is invoked after the appropriate type-specific * <code>endVisit</code> method. The default implementation of this method does nothing. Subclasses * may reimplement this method as needed.</li> * </ul> * <p> * For nodes with list-valued properties, the child nodes within the list are visited in order. For * nodes with multiple properties, the child nodes are visited in the order that most closely * corresponds to the lexical reading order of the source program. For instance, for a type * declaration node, the child ordering is: name, superclass, superinterfaces, and body * declarations. * </p> * <p> * While it is possible to modify the tree in the visitor, care is required to ensure that the * consequences are as expected and desirable. During the course of an ordinary visit starting at a * given node, every node in the subtree is visited exactly twice, first with <code>visit</code> and * then with <code>endVisit</code>. During a traversal of a stationary tree, each node is either * behind (after <code>endVisit</code>), ahead (before <code>visit</code>), or in progress (between * <code>visit</code> and the matching <code>endVisit</code>). Changes to the "behind" region of the * tree are of no consequence to the visit in progress. Changes to the "ahead" region will be taken * in stride. Changes to the "in progress" portion are the more interesting cases. With a node, the * various properties are arranged in a linear list, with a cursor that separates the properties * that have been visited from the ones that are still to be visited (the cursor is between the * elements, rather than on an element). The cursor moves from the head to the tail of this list, * advancing to the next position just <i>before</i> <code>visit</code> if called for that child. * After the child subtree has been completely visited, the visit moves on the child immediately * after the cursor. Removing a child while it is being visited does not alter the course of the * visit. But any children added at positions after the cursor are considered in the "ahead" portion * and will be visited. * </p> * <p> * Cases to watch out for: * <ul> * <li>Moving a child node further down the list. This could result in the child subtree being * visited multiple times; these visits are sequential.</li> * <li>Moving a child node up into an ancestor. If the new home for the node is in the "ahead" * portion, the subtree will be visited a second time; again, these visits are sequential.</li> * <li>Moving a node down into a child. If the new home for the node is in the "ahead" portion, the * subtree will be visited a second time; in this case, the visits will be nested. In some cases, * this can lead to a stack overflow or out of memory condition.</li> * </ul> * <p> * Note that {@link LineComment} and {@link BlockComment} nodes are not normally visited in an AST * because they are not considered part of main structure of the AST.
