 | Expression Interface |
Interface representing an expression for use in select-clauses, where-clauses, having-clauses, order-by clauses and
streams based on filters and pattern filter expressions.
Expressions are organized into a tree-like structure with nodes representing sub-expressions.
Certain types of nodes have certain requirements towards the number or types of nodes that
are expected as sub-expressions to an expression.
