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.
