Public Methods

Method	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.
GreaterJoinExpression ( string leftProperty, string rightProperty ) : System	LeftProperty > RightProperty
GreaterJoinExpression ( string leftProperty, string rightProperty, bool trueOrNot ) : System	LeftProperty > RightProperty
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.

Method Details

Flip() public method

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
return	IJoinExpression

GreaterJoinExpression() public method

LeftProperty > RightProperty

public GreaterJoinExpression ( 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.
return	System

GreaterJoinExpression() public method

LeftProperty > RightProperty

public GreaterJoinExpression ( 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. <=)
return	System

Invert() public method

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 Invert ( ) : IExpression
return	IExpression
