Interface	Description
Expression	Generic interface for all Expressions
ExpressionEvaluator	Interface for implementing an Expression evaluator.
Predicate	An Expression that defines a relation on inputs.

Class Summary

Class	Description

BinaryComparison	A BinaryOperator that compares the left and right Expressions and evaluates to a boolean value.
BinaryExpression	An Expression with two inputs and one output.
BinaryOperator	A BinaryExpression that is an operator, meaning the string representation is x symbol y, rather than funcName(x, y).
Column	A column whose row-value will be computed based on the data in a Row.
EqualTo	Evaluates expr1 = expr2 for new EqualTo(expr1, expr2).
LeafExpression	An Expression with no children.
