Examples of org.mozilla.javascript.ast.AstRoot

org.mozilla.javascript.ast.AstRoot
Node for the root of a parse tree. It contains the statements and functions in the script, and a list of {@link Comment} nodes associated with the scriptas a whole. Node type is {@link Token#SCRIPT}.
Note that the tree itself does not store errors. To collect the parse errors and warnings, pass an {@link org.mozilla.javascript.ErrorReporter} to the{@link org.mozilla.javascript.Parser} via the{@link org.mozilla.javascript.CompilerEnvirons}.
