variable property

String? variable
getter/setter pair

Only present if the child node is SCALAR and corresponds to an output variable of the parent node.

The field carries the name of the output variable. For example, a TableScan operator that reads rows from a table will have child links to the SCALAR nodes representing the output variables created for each column that is read by the operator. The corresponding variable fields will be set to the variable names assigned to the columns.

Implementation

core.String? variable;
