Méthodes publiques

Méthode	Description
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.
LesserJoinExpression ( string leftProperty, string rightProperty ) : System	LeftProperty < RightProperty
LesserJoinExpression ( string leftProperty, string rightProperty, bool trueOrNot ) : System	LeftProperty < RightProperty

Flip() public méthode

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 Flip ( ) : IJoinExpression
Résultat	IJoinExpression

Invert() public méthode

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.

Résultat	IExpression

LesserJoinExpression() public méthode

LeftProperty < RightProperty

public LesserJoinExpression ( string leftProperty, string rightProperty ) : System
leftProperty	string	The name of the property on the object returned by the /// left DAO that we are comparing.
rightProperty	string	The name of the property on the object returned by the /// right DAO that we are comparing.
Résultat	System

LesserJoinExpression() public méthode

LeftProperty < RightProperty

public LesserJoinExpression ( string leftProperty, string rightProperty, bool trueOrNot ) : System
leftProperty	string	The name of the property on the object returned by the /// left DAO that we are comparing.
rightProperty	string	The name of the property on the object returned by the /// right DAO that we are comparing.
trueOrNot	bool	True means look for matches (I.E. <), /// false means look for non-matches (I.E. >=)
Résultat	System
