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. Use * {@link CompilationUnit#getCommentList()} to find these additional * comments nodes. * </p> * * @see org.eclipse.jdt.core.dom.ASTNode#accept(ASTVisitor) */ public abstract class ASTVisitor { /** * Indicates whether doc tags should be visited by default. * @since 3.0 */ private boolean visitDocTags; /** * Creates a new AST visitor instance. * <p> * For backwards compatibility, the visitor does not visit tag * elements below doc comments by default.
