    47  * Root class for abstract syntax tree nodes. It provides definitions
    48  * for specific tree nodes as subclasses nested inside.
    49  *
    50  * <p>Each subclass is highly standardized.  It generally contains
    51  * only tree fields for the syntactic subcomponents of the node.  Some
    52  * classes that represent identifier uses or definitions also define a
    53  * Symbol field that denotes the represented identifier.  Classes for
    54  * non-local jumps also carry the jump target as a field.  The root
    55  * class Tree itself defines fields for the tree's type and position.
    56  * No other fields are kept in a tree node; instead parameters are
    57  * passed to methods accessing the node.
    58  *
    59  * <p>Except for the methods defined by com.sun.source, the only
    60  * method defined in subclasses is `visit' which applies a given
    61  * visitor to the tree. The actual tree processing is done by visitor
    62  * classes in other packages. The abstract class Visitor, as well as
    63  * an Factory interface for trees, are defined as inner classes in
    64  * Tree.
    65  *
    66  * <p>To avoid ambiguities with the Tree API in com.sun.source all sub
    67  * classes should, by convention, start with JC (javac).
    68  *
    69  * <p><b>This is NOT part of any supported API.
    70  * If you write code that depends on this, you do so at your own risk.
    71  * This code and its internal interfaces are subject to change or
    72  * deletion without notice.</b>
