Class TPowerQueryLetExpr

Object

gudusoft.gsqlparser.nodes.TParseTreeNode

gudusoft.gsqlparser.nodes.powerquery.TPowerQueryLetExpr

All Implemented Interfaces:

Visitable, Iterator<TSourceToken>

public class TPowerQueryLetExpr
extends TParseTreeNode

Power Query M-Language let ... in ... document container.

Holds the ordered list of step bindings (name = expression) plus the identifier that the in clause returns. Mirrors the parse-graph shape produced by PowerQuerySqlParser.

This is the root node of a parsed M document. Lineage extraction walks this container to find TPowerQueryNativeQuery and TPowerQueryNavChain steps.
