Class Summary

Class	Description
And	Evaluates logical expr1 AND expr2 for new And(expr1, expr2).
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 RowRecord.
EqualTo	Evaluates expr1 = expr2 for new EqualTo(expr1, expr2).
GreaterThan	Evaluates expr1 > expr2 for new GreaterThan(expr1, expr2).
GreaterThanOrEqual	Evaluates expr1 >= expr2 for new GreaterThanOrEqual(expr1, expr2).
In	Evaluates if expr is in exprList for new In(expr, exprList).
IsNotNull	Evaluates if expr is not null for new IsNotNull(expr).
IsNull	Evaluates if expr is null for new IsNull(expr).
LeafExpression	An Expression with no children.
LessThan	Evaluates expr1 < expr2 for new LessThan(expr1, expr2).
LessThanOrEqual	Evaluates expr1 <= expr2 for new LessThanOrEqual(expr1, expr2).
Literal	A literal value.
Not	Evaluates logical NOT expr for new Not(expr).
Or	Evaluates logical expr1 OR expr2 for new Or(expr1, expr2).
UnaryExpression	An Expression with one input and one output.
