| OpcFilterOperand | Initializes a new instance of the OpcFilterOperand class using the content specified. |
Methods
| Name | Description |
|---|---|
| Between | Creates an element which determines whether this operand is greater than or equal to the lower value and less than or equal to the upper value. |
| Cast | Creates an element which converts this operand to the data type identified by the right value. |
| Equals | Determines whether the specified other is equal to this OpcFilterOperand. |
| EqualsTo | Creates an element which determines whether this operand is equal to the right value. |
| GetHashCode | Retrieves a hash code for this OpcFilterOperand. |
| GreaterThan | Creates an element which determines whether this operand is greater than the right value. |
| Greater | Creates an element which determines whether this operand is greater than or equal to the right value. |
| InList | Creates an element which determines whether this operand is equal to the item or one of the items specified. |
| InView | Creates an element which determines whether the node the filter is applied to is contained in the view identified by this operand. |
| IsNull | Creates an element which determines whether this operand is a null value. |
| LessThan | Creates an element which determines whether this operand is less than the right value. |
| Less | Creates an element which determines whether this operand is less than or equal to the right value. |
| Like | Creates an element which determines whether this operand matches the pattern of the right value. |
| Not | Creates an element which determines whether this operand, a Boolean value, is false. |
| OfType | Creates an element which determines whether the node the filter is applied to is of the type identified by this operand. |
| ToString | Returns a string that represents the operand. |
Operators
| Name | Description |
|---|---|
| Equality | Creates an element which determines whether the left operand is equal to the right value. |
| GreaterThan | Creates an element which determines whether the left operand is greater than the right value. |
| Greater | Creates an element which determines whether the left operand is greater than or equal to the right value. |
| Inequality | Not supported. |
| LessThan | Creates an element which determines whether the left operand is less than the right value. |
| LessThanOrEqual | Creates an element which determines whether the left operand is less than or equal to the right value. |
