Class ASTNodeWriterAbstract

Generate a SrcDesc for a given node, but without adding the node itself to the tree.

Add the node to the descrioption generated by writeInner, any additional "wrappings" and return it. Usually writeWhole is responsible for adding semicolons and documentation, since these are not generally part of source mappings.

For example given this source:

a = 1;
Copy

ExpressionStatement.writeInner would return the following desc:

[[Assignment#3, [[Identifier#1, ["a"]], " = ", [Literal#2, ["1"]] ]]]
Copy

Then ExpressionStatement.writeWhole would add in the ExpressionStatement node and the semicolon to return:

[[ExpressionStatement#4, [[Assignment#3, [[Identifier#1, ["a"]], " = ", [Literal#2, ["1"]] ]]]], ";"]
Copy
