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

---

Fires before outgoing evvelopes were processed

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

---

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)

---

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)

---

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)

---

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)

---

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)

---

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)

---

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)

---

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)

---

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

---

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)

---

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)

---

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)

---

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)

---

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)

---

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)

---

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)

---

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)
