/**
|
|
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.
|
