Class used to pass soap or mtom messages from a transport service to the message processor.

Creates an instance of a WsRequestMessage class an initializes the soap message property.

A byte array containing a soap request message. This class is used to create a simple soap request message object. Because Mtom message are identified via transport header fields (yuck) this class is required to abstract the transport messages. The transport services create this object and pass it to a message processor. With this contructor the request message is simply stored in the SoapMessage property. ///

Creates an instance of a WsRequestMessage class, parses the message into mtom body parts and assigns the start body part to the SoapMessage property.

A byte array containing the message received by a transport. A string containing a boundary element if the transport received an mtom message. A string containing the ID of the mtom body part that contains the soap envelope of the mtom attachment. Because Mtom message are identified via transport header fields (yuck). The transport services create this object and pass it to a message processor. If this is a normal soap request, no additional processing is required and the SoapMessage property is set to the request message. If this is an Mtom message, the transport header contains an mtom boundary element and start content id needed to parse the mtom message. The boundary element is used to identify the start and end of mtom body parts sections. The start content id is used to identify the specific mtom body part that contains a soap envelope that references the additional body part elements. If an mtom message is created the constructor parses the mtom message and creates an mtom body parts object. For mtom the constructor also sets the SoapMessage property to the body part identified by the startContentID parmeter. If the message parameter is null.
