Package org.apache.drill.common.expression Description
Logical expression tree representation.
Drill manages expressions provided in many different parts of SQL queries.
This includes scalar expressions in select, filter and join conditions, as
well as aggregate and window functions. These expressions are represented
logically as ASTs during planning. The classes defined here provide the
different nodes in the expression tree, as well as utilities for building
and manipulating expressions during parsing and planning.
