public java.lang.String toSource(int depth)
AstNode
Note: if the parser was in error-recovery mode, some AST nodes may have
null children that are expected to be non-null
when no errors are present. In this situation, the behavior of the
toSource method is undefined: toSource
implementations may assume that the AST node is error-free, since it is
intended to be invoked only at runtime after a successful parse.
toSource in class AstNodedepth - the current recursion depth, typically beginning at 0
when called on the root node.public void visit(NodeVisitor v)
visit in class AstNodev - the object to call with this node and its children
