PortType Element (Windows CE 5.0)
The <portType> element in a Web Services Description Language (WSDL) file identifies a set of operations and the messages involved with each operation.
The following code example of the Calc.wsdl file shows the <portType> element named CalcSoapPort.
In this WSDL file, there is only one <portType> element. However, other files might include multiple <portType> elements, each of which describes a specific set of operations and associated messages.
<portType name='CalcSoapPort'>
<operation name='Multiply' parameterOrder='A B'>
<input message='wsdlns:Calc.Multiply' />
<output message='wsdlns:Calc.MultiplyResponse' />
</operation>
<operation name='Divide' parameterOrder='A B'>
<input message='wsdlns:Calc.Divide' />
<output message='wsdlns:Calc.DivideResponse' />
</operation>
<operation name='Subtract' parameterOrder='A B'>
<input message='wsdlns:Calc.Subtract' />
<output message='wsdlns:Calc.SubtractResponse' />
</operation>
<operation name='Add' parameterOrder='A B'>
<input message='wsdlns:Calc.Add' />
<output message='wsdlns:Calc.AddResponse' />
</operation>
</portType>
The CalcSoapPort element has four <operation> child elements, each of which describes an operation.
The name attribute of the <operation> element identifies the various operations: Multiply, Divide, Subtract, and Add.
All of these operations are request-response operations in which the <input> element specifies the message format for the request and the <output> element specifies the message format for the response.
Each <input> and <output> element has an optional name attribute that identifies that message. In this sample, this name attribute is missing. These names must be unique among all <input> and <output> elements within the enclosing <portType>.
