TROWinMessageServer

 

Standard component constructor

constructor Create(aOwner: TComponent)

Parameters:

• aOwner: Owner

---

Toggles whether the server ready to receive requests from clients. Depending on the server type, changing this property might open/close a network socket or otherwise toggle whether the server will process incoming requests.

property Active: Boolean read write

---

Represents the event repository provided by the server.

property ActiveEventRepository: TROEventRepository read write

---

Copies the contents of another, similar object.

procedure Assign(Source: TPersistent)

Parameters:

• Source: Instance whose properties will be copied

---

Validates the server properties.

procedure CheckProperties

---

Decrypt stream

procedure DecryptStream(const Source: TStream; const Dest: TStream)

Parameters:

• Source: Source
• Dest: Destination

---

Decrypt stream

procedure DecryptStream(const Stream: TStream)

Parameters:

• Stream: Stream

---

Holds the message that will be sent back to the client if it improperly "welcomes" the server.

property DefaultResponse: string read write

---

Specifies how incoming requests will be processed and dispatched. Depending on the server type, one or multiple dispatchers can be configured to receive messages from the client. Each dispatcher consists of a Message and an optional Name. Also, each dispatcher can be individually enabled or disabled. Each server must have at least one dispatcher configured, in order to be able to process messages.

=Essential Sub-Properties=

• Message specifies the message format to be used for this dispatcher.
• Name specifies the name, or possibly the URL for the dispatcher.

In HTTP based servers (such as the TROIndyHTTPServer, the Name will be appended as folder to the server URL allowing the server to make multiple dispatchers available at different URLs.

property ServerID: string read write

---

Specifies whether the server will make the contained RODL file available to clients (true, default) or not. Keep this property set to true if clients need to access the RODL (or WSDL), for example so that third parties (including Service Tester) can import services. Set it to false if you do not want to provide this information, for example for security reasons.

property ServeRodl: Boolean read write

---
