@Deprecated
public final java.lang.String getOriginalName()

        "original name" is poorly defined.
        The original name of this node, if the node has been renamed.

        Do not use original name to make optimization decisions. The original intent was to preserve some naming for lightly optimized code to put into source maps. It is not rigorously defined and is not a suitable replacement for a canonical identifier. "Original name" is not associated with any scope and easily transfers to unrelated values. Its existance and use beyond its original purpose has delayed creating useful more precise alternatives.

      • setOriginalName

        public final void setOriginalName​(java.lang.String s)

        Merges the line number and character number in one integer.

        The charno takes the first 12 bits and the line number takes the rest. If the charno is greater than (2^12)-1 it is adjusted to (2^12)-1

      • children

        @Deprecated
public final java.lang.Iterable<Node> children()
        Deprecated.
        Return an iterable object that iterates over this node's children. The iterator does not support the optional operation Iterator.remove().

        To iterate over a node's children, one can write 

        Node n = ...;
 for (Node child : n.children()) { ...
        NOTE: Do not use 'children' for recursive descent of the AST. The overhead of using iterators rather then getFirstChild()/getNext() is very significant. We have deprecated it as it is easy to misuse.
