55 /**
56 * Root class for abstract syntax tree nodes. It provides definitions
57 * for specific tree nodes as subclasses nested inside.
58 *
59 * <p>Each subclass is highly standardized. It generally contains
60 * only tree fields for the syntactic subcomponents of the node. Some
61 * classes that represent identifier uses or definitions also define a
62 * Symbol field that denotes the represented identifier. Classes for
63 * non-local jumps also carry the jump target as a field. The root
64 * class Tree itself defines fields for the tree's type and position.
65 * No other fields are kept in a tree node; instead parameters are
66 * passed to methods accessing the node.
67 *
68 * <p>Except for the methods defined by com.sun.source, the only
69 * method defined in subclasses is `visit' which applies a given
70 * visitor to the tree. The actual tree processing is done by visitor
71 * classes in other packages. The abstract class Visitor, as well as
72 * an Factory interface for trees, are defined as inner classes in
73 * Tree.
74 *
75 * <p>To avoid ambiguities with the Tree API in com.sun.source all sub
76 * classes should, by convention, start with JC (javac).
77 *
78 * <p><b>This is NOT part of any supported API.
79 * If you write code that depends on this, you do so at your own risk.
80 * This code and its internal interfaces are subject to change or
81 * deletion without notice.</b>
