Public Properties

Method	Description
Clear ( ) : void	Completely clears the object so that it may be used over again.
CopyFrom ( DaoCriteria other ) : void	Makes this DaoCriteria into a copy of the other one. Any existing orders, expressions, etc. on this one are lost.
DaoCriteria ( ) : System	Constructs a blank criteria, which will return all records unless you customize it. All expressions added to it will be ANDed together.
DaoCriteria ( BooleanOperator howToAddExpressions ) : System	Constructs a blank criteria, which will return all records unless you customize it.
DaoCriteria ( IExpression firstExpr ) : System	Constructs a criteria with one expression. May be handy for cases where you only need one expression.
DaoCriteria ( IExpression firstExpr, BooleanOperator howToAddExpressions ) : System	Constructs a criteria with one expression.

Completely clears the object so that it may be used over again.

public Clear ( ) : void
return	void

Makes this DaoCriteria into a copy of the other one. Any existing orders, expressions, etc. on this one are lost.

public CopyFrom ( DaoCriteria other ) : void
other	DaoCriteria	Criteria to copy everything from.
return	void

Constructs a blank criteria, which will return all records unless you customize it. All expressions added to it will be ANDed together.

public DaoCriteria ( ) : System
return	System

Constructs a blank criteria, which will return all records unless you customize it.

public DaoCriteria ( BooleanOperator howToAddExpressions ) : System
howToAddExpressions	BooleanOperator	How expressions will be added together. Determines /// if we do exp1 AND exp2 AND exp3, or if we do /// exp1 OR exp2 OR exp3.
return	System

Constructs a criteria with one expression. May be handy for cases where you only need one expression.

public DaoCriteria ( IExpression firstExpr ) : System
firstExpr	IExpression	The first expression to add.
return	System

Constructs a criteria with one expression.

public DaoCriteria ( IExpression firstExpr, BooleanOperator howToAddExpressions ) : System
firstExpr	IExpression	The first expression to add.
howToAddExpressions	BooleanOperator	How expressions will be added together. Determines /// if we do exp1 AND exp2 AND exp3, or if we do /// exp1 OR exp2 OR exp3.
return	System

Whether this is an "AND" criteria or an "OR" criteria.

public BooleanOperator BoolType
return	BooleanOperator

The individual expressions that make up this criteria. Defaults to empty. Expressions can be added, cleared, etc.

public List Expressions
return	List

Used to limit the data returned, only data rows Start to Start + Limit will be returned. A value of -1 means ignore this parameter.

public int Limit
return	int

The list of properties to sort on. Defaults to empty, you may add, clear, reorder, etc.

public List Orders
return	List

Used to limit the data returned, only data rows Start to Start + Limit will be returned. A value of -1 means ignore this parameter.

public int Start
return	int
