procedure ApplyAttributes2_Transport(aTransport: IROTransport)

Parameters:


Assign  override

Copies the contents of another, similar object.

procedure Assign(Source: TPersistent)

Parameters:

  • Source: Instance whose properties will be copied

BinaryType

Selects what format will be used to encode binary data, Hex or Base64.

property BinaryType: TROPostMessageBinaryType read write

CheckForEnvelope    (declared in TROMessage)

Writes the content of the message to aStream.

class function CheckForEnvelope(Source: TStream; var aEnvelopeName: string): Boolean

ClientID    (declared in TROMessage)

Contains the Client ID for the message. Client IDs are used by the Remoting SDK for Session Management and to uniquely identify individual client on the server, for example by the Per-Client Class Factory or in your own custom code. Generally, you will not need to assign or read this value; the framework will automatically create a new unique client ID whenever a message object is instantiated on the client. However, you do have the option to read and write the ClientID property manually, for example to persist a specific client ID between shutdown and restart of your application.

OnAfterProcessIncomingEnvelopes    (declared in TROMessage)

Fires after incoming envelopes were processed

property OnAfterProcessIncomingEnvelopes: TStreamOperation read write
delegate: procedure OnAfterProcessIncomingEnvelopes(aStream: TStream)

OnAfterProcessOutgoingEnvelopes    (declared in TROMessage)

Fires after outgoing envelopes were processed

property OnAfterProcessOutgoingEnvelopes: TStreamOperation read write
delegate: procedure OnAfterProcessOutgoingEnvelopes(aStream: TStream)

OnBeforeProcessIncomingEnvelopes    (declared in TROMessage)

Fires before incoming envelopes were processed

property OnBeforeProcessIncomingEnvelopes: TStreamOperation read write
delegate: procedure OnBeforeProcessIncomingEnvelopes(aStream: TStream)

OnBeforeProcessOutgoingEnvelopes    (declared in TROMessage)

Fires before outgoing evvelopes were processed

property OnBeforeProcessOutgoingEnvelopes: TStreamOperation read write
delegate: procedure OnBeforeProcessOutgoingEnvelopes(aStream: TStream)

OnFinalizeMessage    (declared in TROMessage)

Fires as a message object is getting finalized, to send a new request or response. This happens after the entire message has been generated, all parameters have been added, and the message is ready to be sent off over the network.

property OnFinalizeMessage: TROFinalizeMessageEvent read write
delegate: procedure OnFinalizeMessage(Sender: TROMessage)

OnInitializeMessage    (declared in TROMessage)

Fires as a message object is getting initialized, to send a new request or response. This happens after the basic message options are set, but before any parameters or data have been stored in the message.

property OnInitializeMessage: TROInitializeMessageEvent read write
delegate: procedure OnInitializeMessage(Sender: TROMessage; const aTransport: IROTransport; const anInterfaceName: string; const aMessageName: string)

OnReadFromStream    (declared in TROMessage)

Fires before the message is read from the stream that was received over the network. You can use this event to inspect the received stream, or to make manual modifications to it, for example to apply any custom decryption to the message stream before it is processed.

property OnReadFromStream: TStreamOperation read write
delegate: procedure OnReadFromStream(aStream: TStream)

OnReadMessageParameter    (declared in TROMessage)

Fires after an individual message parameter has been read from the received message. The event call will include information about the name and type of the parameter, as well as an untyped pointer to the data. Use this event handler to inspect or log the parameters that are received. In theory, it is also possible to modify the value parameter using the DataRef pointer, but this should be done with extreme caution.

property OnReadMessageParameter: TROReadMessageParameterEvent read write
delegate: procedure OnReadMessageParameter(Sender: TROMessage; const aName: string; aTypeInfo: PTypeInfo; const DataRef: Pointer; Attributes: TParamAttributes)

OnServerException    (declared in TROMessage)

Fires if an exception message is received from the server. Use this event handler to provide a single point of interception to be notified of all exceptions raised on the server. In contrast to the TROTransportChannel's OnException event, this event will not fire for communication errors or local exceptions during the processing of a request, but only for exceptions that truly originated on the server.

property OnServerException: TROServerExceptionEvent read write
delegate: procedure OnServerException(anException: Exception; var RaiseException: Boolean)

OnWriteException    (declared in TROMessage)

Fires after an exception message was written to the stream that will be sent over the network. This event will fire in addition to (and before) the OnWriteToStream event. You can use this event to inspect the exception message or the outgoing stream.

property OnWriteException: TROWriteExceptionEvent read write
delegate: procedure OnWriteException(Sender: TROMessage; aStream: TStream; E: Exception)

OnWriteMessageParameter    (declared in TROMessage)

Fires before an individual message parameter will be written to the outgoing message. The event call will include information about the name and type of the parameter, as well as an untyped pointer to the data.

property OnWriteMessageParameter: TROWriteMessageParameterEvent read write
delegate: procedure OnWriteMessageParameter(Sender: TROMessage; const aName: string; aTypeInfo: PTypeInfo; const DataRef: Pointer; Attributes: TParamAttributes)

OnWriteToStream    (declared in TROMessage)

Fires after the message was written to the stream that will be sent over the network. You can use this event to inspect the outgoing stream, or to make manual modifications to it, e.g. to apply any custom encryption to the message stream before it is sent off.

property OnWriteToStream: TStreamOperation read write
delegate: procedure OnWriteToStream(aStream: TStream)
