Package polyglot.ast Description

Contains the AST node interfaces.

The nodes all extend the interface Node. Each node has accessor methods and methods to implement passes over the node. The setter methods are non-destructive: they create a copy of the node and return the copy. The traversal interface is defined in NodeVisitor. Nodes are constructed using a NodeFactory.
