Interface SQLOperator

All Superinterfaces:

SQLExpression

All Known Implementing Classes:

Arithmetic.Add, Arithmetic.BitAnd, Arithmetic.BitOr, Arithmetic.Div, Arithmetic.Mul, Arithmetic.Sub, Conditionals.Equals, Conditionals.Exists, Conditionals.FullTextMatch, Conditionals.GreaterThan, Conditionals.GreaterThanEquals, Conditionals.In, Conditionals.IsNull, Conditionals.LessThan, Conditionals.LessThanEquals, Conditionals.Like, Conditionals.NotEquals, Logic.And, Logic.Not, Logic.Or, SQLOperator.BinaryOperator, SQLOperator.MultiOperator

public interface SQLOperator
extends SQLExpression

A common interface for operator hierarchies in SQL. The main purpose of breaking this out from SQLExpression is to capture the recursive nature of e.g. the logical operators, which work on other SQLOperators but not general SQLExpressions.

Nested Class Summary

static class	SQLOperator.BinaryOperator Does the real work for simple binary operators such as Equals.
static class	SQLOperator.MultiOperator Represents an operator with any number of operands.
