SimpleCriteriaType

Applies To: Operations Manager 2007 R2

The SimpleCriteriaType complex data type is used to define an expression that compares two values of the same type.

The SimpleCriteriaType data type is generally used from within the ExpressionType schema data type.

Schema Definition

<xsd:complexType name="SimpleCriteriaType">
  <xsd:sequence>
    <xsd:element name="ValueExpression" type="ValueExpressionType"/>
    <xsd:element name="Operator">
      <xsd:complexType>
        <xsd:simpleContent>
          <xsd:extension base="CriteriaCompareType">
            <xsd:attribute name="CaseSensitive" type="xsd:boolean" use="optional" default="false"/>
          </xsd:extension>
        </xsd:simpleContent>
      </xsd:complexType>
    </xsd:element>
    <xsd:element name="ValueExpression" type="ValueExpressionType"/>
  </xsd:sequence>
</xsd:complexType>

Remarks

The SimpleCriteriaType data type evaluates two values by using a simple comparison (equal, not equal, less than, greater than, less than or equal, greater than or equal). The two values can be cast to the appropriate type for comparison.

The SimpleCriteriaType data type contains the parameters described in the following table.

Parameter	Type	Description
ValueExpression	ValueExpressionType	Required parameter. The value that represents the left side of the operand.
Operator	CriteriaCompareType	Required parameter. Defines the operation to perform to compare the left and right values.
ValueExpression	ValueExpressionType	Required parameter. The value that represents the right side of the operand.

The following sample XML uses the “Equal” operator to compare two values. The left value is a constant string. The right value is an XPath query into the incoming data item. The $Data reference is not required because implementation of the XPathQuery element implies it.

<Expression>
  <SimpleExpression>
    <ValueExpression>
      <Value>EventCreate</Value>
    </ValueExpression>
    <Operator>Equal</Operator>
    <ValueExpression>
      <XPathQuery>PublisherName</XPathQuery>
    </ValueExpression>
  </SimpleExpression>
</Expression>
