Pascal

procedure Execute(const DataMsg: String; Resp: TStream); virtual; overload;
procedure Execute(const Request: TStream; Response: TStream); virtual; overload;
function Execute(const Request: TStream): TStream; overload;

C++

__fastcall TStream Execute(const TStream Request);

Description

Execute implements the IWebNode method of the same name. TLinkedRio uses this method to execute a method on an invokable interface that has been encoded as a SOAP method call.

Execute

Uses the invocation registry to look up the implementation class for the invokable interface.
Uses its internal invoker (the Invoker property) to unmarshal the request specified by Request or DataMsg and pass it to the implementation class for execution.
Returns the encoded results from the invoker in the stream specified by Response or, using the third syntax, in a stream that is the return value of the method. When using the third syntax, the caller is responsible for freeing the returned stream.
