C# Класс Azavea.Open.DAO.Criteria.Joins.AbstractJoinExpression

Наследование: IJoinExpression

Защищенные свойства (Protected)

Свойство	Тип	Описание
_trueOrNot	bool

Открытые методы

Метод	Описание
Flip ( ) : IJoinExpression	For some implementations, it's simpler to only implement one-sided joins. So to handle right (or left) joins, you want to flip the criteria so the right and left daos are swapped and you can do a left (or right) join instead.
Invert ( ) : IExpression	Produces an expression that is the exact opposite of this expression. The new expression should exclude everything this one includes, and include everything this one excludes.
ToString ( ) : string
TrueOrNot ( ) : bool	This tells you whether you want things that match, or things that don't match, this expression.

Защищенные методы

Метод	Описание
AbstractJoinExpression ( bool trueOrNot ) : System	This lets you specify whether to negate this expression.

Описание методов

AbstractJoinExpression() защищенный Метод

This lets you specify whether to negate this expression.

protected AbstractJoinExpression ( bool trueOrNot ) : System
trueOrNot	bool	True means look for matches (I.E. ==), /// false means look for non-matches (I.E. !=)
Результат	System

Flip() публичный абстрактный Метод

For some implementations, it's simpler to only implement one-sided joins. So to handle right (or left) joins, you want to flip the criteria so the right and left daos are swapped and you can do a left (or right) join instead.

public abstract Flip ( ) : IJoinExpression
Результат	IJoinExpression

Invert() публичный абстрактный Метод

Produces an expression that is the exact opposite of this expression. The new expression should exclude everything this one includes, and include everything this one excludes.

public abstract Invert ( ) : IExpression
Результат	IExpression

ToString() публичный Метод

public ToString ( ) : string
Результат	string

TrueOrNot() публичный Метод

This tells you whether you want things that match, or things that don't match, this expression.

public TrueOrNot ( ) : bool
Результат	bool

Описание свойств

_trueOrNot защищенное свойство

Holds the value indicating whether this expression is negated.
