Examples of JCTree

com.sun.tools.javac.tree.JCTree
Root class for abstract syntax tree nodes. It provides definitions for specific tree nodes as subclasses nested inside.
Each subclass is highly standardized. It generally contains only tree fields for the syntactic subcomponents of the node. Some classes that represent identifier uses or definitions also define a Symbol field that denotes the represented identifier. Classes for non-local jumps also carry the jump target as a field. The root class Tree itself defines fields for the tree's type and position. No other fields are kept in a tree node; instead parameters are passed to methods accessing the node.
Except for the methods defined by com.sun.source, the only method defined in subclasses is `visit' which applies a given visitor to the tree. The actual tree processing is done by visitor classes in other packages. The abstract class Visitor, as well as an Factory interface for trees, are defined as inner classes in Tree.
To avoid ambiguities with the Tree API in com.sun.source all sub classes should, by convention, start with JC (javac).
This is NOT part of any supported API. If you write code that depends on this, you do so at your own risk. This code and its internal interfaces are subject to change or deletion without notice. @see TreeMaker @see TreeInfo @see TreeTranslator @see Pretty
