50 | * Root class for abstract syntax tree nodes. It provides definitions |
51 | * for specific tree nodes as subclasses nested inside. |
52 | * |
53 | * <p>Each subclass is highly standardized. It generally contains |
54 | * only tree fields for the syntactic subcomponents of the node. Some |
55 | * classes that represent identifier uses or definitions also define a |
56 | * Symbol field that denotes the represented identifier. Classes for |
57 | * non-local jumps also carry the jump target as a field. The root |
58 | * class Tree itself defines fields for the tree's type and position. |
59 | * No other fields are kept in a tree node; instead parameters are |
60 | * passed to methods accessing the node. |
61 | * |
62 | * <p>Except for the methods defined by com.sun.source, the only |
63 | * method defined in subclasses is `visit' which applies a given |
64 | * visitor to the tree. The actual tree processing is done by visitor |
65 | * classes in other packages. The abstract class Visitor, as well as |
66 | * an Factory interface for trees, are defined as inner classes in |
67 | * Tree. |
68 | * |
69 | * <p>To avoid ambiguities with the Tree API in com.sun.source all sub |
70 | * classes should, by convention, start with JC (javac). |
71 | * |
72 | * <p><b>This is NOT part of any API supported by Sun Microsystems. |
73 | * If you write code that depends on this, you do so at your own risk. |
74 | * This code and its internal interfaces are subject to change or |
75 | * deletion without notice.</b> |
