In the legacy version of the iWay .NET Technology Adapter, the following primary functions are used to handle XML schema generation for a method:

• ComposeDocMethod
• ComposeRpcMethod

Note: In legacy mode, there is limited support for defined complex types. It is recommended to use the new dynamic schema methods for methods with complex types.

The earlier version of the iWay .NET Technology Adapter requires a custom .NET wrapper, or at least recompilation, to consume assemblies. The custom .NET wrapper references iwclr.dll and wraps a target .NET assembly to provide schemas or descriptions for methods by adding special attributes, which will be retrieved by iwclr.dll. The following primary attributes are provided by a wrapper for a method:

• XmlInXmlOutAttribute

  [XmlInXmlOutAttribute(METHODDESCRIPTION, ROOTELEMENT, RAWINPUTSCHEMA, OUTPUTDATANAME, RAWOUTPUTSCHEMA)]
  public XmlElement Add (XmlElement input)
  {//codes }

• ParamsInParamsOutAttribute

  [ParamsInParamsOutAttribute(METHODDESCRIPTION)] public double Sqrt (double number)
  {//code }

The following table lists and describes the key words that are allowed.

Key Word	Type	Description
METHODDESCRIPTION	String	The description of a method.
SCHEMAROOTELEMENT	String	The name of a root element (normally, It is the name of a method).
RAWINPUTSCHEMA	String	Raw request schema (a schema is retrieved from a attribute of a wrapper).
OUTPUTDATANAME	String	The name of an output data.
RAWOUTPUTSCHEMA	String	Raw response schema (a schema is retrieved from a attribute of a wrapper).
