NotOperator Members

The logical NOT operation that inverts an operand.

Constructors

Name Description
NotOperator() Initializes a new instance of the NotOperator class with the default settings.
NotOperator(CriteriaOperator) Initializes a new NotOperator instance that inverts the specified operator.

Fields

Name Description
Operand The operand on which the operator acts. Inherited from UnaryOperator.
OperatorType The operand on which the operator acts. Inherited from UnaryOperator.

Properties

Name Description
CustomFunctionCount static Returns the number of registered custom functions. Inherited from CriteriaOperator.

Methods

Name Description
Accept(ICriteriaVisitor) For internal use only. Accepts the specified visitor. Inherited from UnaryOperator.

And(CriteriaOperator, CriteriaOperator) static Initializes a new CriteriaOperator that groups specified criteria via the logical AND operator. Inherited from CriteriaOperator.
And(CriteriaOperator[]) static Initializes a new CriteriaOperator that groups specified criteria via the logical AND operator. Inherited from CriteriaOperator.
And(IEnumerable<CriteriaOperator>) static Initializes a new CriteriaOperator that groups specified criteria via the logical AND operator. Inherited from CriteriaOperator.
Clone() Initializes a new UnaryOperator instance that is a copy of the current instance. Inherited from UnaryOperator.
Clone(CriteriaOperator) static Initializes a new CriteriaOperator instance that is a copy of the specified instance instance. Inherited from CriteriaOperator.

CloneCommon() protected Inherited from UnaryOperator.
CriterionEquals(CriteriaOperator, CriteriaOperator) static Determines whether the specified CriteriaOperators are equal. Inherited from CriteriaOperator.
Equals(Object, Object) static Determines whether the specified object instances are considered equal. Inherited from Object.
Equals(Object) Determines whether the specified object is equal to the current UnaryOperator instance. Inherited from UnaryOperator.
GetCustomFunction(String) static Returns a registered custom function with the specified name. Inherited from CriteriaOperator.
GetCustomFunctions() static Returns all registered custom functions. Inherited from CriteriaOperator.
GetHashCode() Serves as the default hash function. Inherited from UnaryOperator.
GetType() Gets the Type of the current instance. Inherited from Object.
IsNotNull() Initializes a new UnaryOperator instance that checks whether the current criterion is not null. Inherited from CriteriaOperator.
IsNull() Initializes a new UnaryOperator instance that checks whether the current criterion is null. Inherited from CriteriaOperator.
LegacyToString() Converts the current expression into its string equivalent and removes value suffixes (like 'm', 'M', 'l', 'L', etc.) Inherited from CriteriaOperator.
LegacyToString(CriteriaOperator) static Converts the specified expression into its string equivalent and removes value suffixes (like 'm', 'M', 'l', 'L', etc.) Inherited from CriteriaOperator.
MemberwiseClone() protected Creates a shallow copy of the current Object. Inherited from Object.
Not() Initializes a new UnaryOperator instance that applies the logical NOT operator to the current criterion. Inherited from CriteriaOperator.
ObjectToCriteriaSafe(Object) protected static Inherited from CriteriaOperator.
Or(CriteriaOperator, CriteriaOperator) static Initializes a new CriteriaOperator that groups specified criteria via the logical OR operator. Inherited from CriteriaOperator.
Or(CriteriaOperator[]) static Initializes a new CriteriaOperator that groups specified criteria via the logical OR operator. Inherited from CriteriaOperator.

Parse(String, out OperandValue[]) static Converts the specified string into its CriteriaOperator equivalent. Throws an exception if it cannot convert the string to a criterion. Inherited from CriteriaOperator.
Parse(String, Object[]) static Converts the specified string into its CriteriaOperator equivalent. Throws an exception if it cannot convert the string to a criterion. Inherited from CriteriaOperator.
ParseList(String, out OperandValue[]) static Converts the specified string into its CriteriaOperators equivalent. Expressions should be divided by a semicolon (';'). Throws an exception if it cannot convert the string to criteria. Inherited from CriteriaOperator.
ParseList(String, Object[]) static Converts the specified string into its CriteriaOperators equivalent. Expressions should be divided by a semicolon (';'). Throws an exception if it cannot convert the string to criteria. Inherited from CriteriaOperator.
