Error Event

Fired when a component or protocol error occurs.

Syntax

typedef struct {
  int ErrorCode;
  String Description;
  String Data;
  DynamicArray<Byte> DataB;
} TipqSTOMPErrorEventParams;

typedef void __fastcall (__closure *TipqSTOMPErrorEvent)(System::TObject* Sender, TipqSTOMPErrorEventParams *e);

__property TipqSTOMPErrorEvent OnError = { read=FOnError, write=FOnError };

Remarks

The Error event is fired in case of exceptional conditions during message processing. Normally the component raises an exception.

ErrorCode contains an error code and Description contains a textual description of the error. For a list of valid error codes and their descriptions, please refer to the Error Codes section.

STOMP Protocol Errors

The component will fire the Error event anytime the server reports a STOMP protocol error (i.e., the component receives an ERROR frame).

When this occurs, ErrorCode will be 600, Description will reflect the value of the ERROR frame's message header, and Data will contain the body of the ERROR frame (if one is present).

The ErrorHeaders configuration setting will also be populated with the raw headers from the ERROR frame for the duration of the Error event handler.
