Exception type for protocol reply errors.

EIdProtocolReplyError = class(EIdException)

EIdProtocolReplyError is an EIdException descendant tha represents the exception type raised for protocol replies that represent an error condition. EIdProtocolReplyError is also used as the ancestor for more specific protocol reply errors, like EIdHTTPProtocolException and EIdNNTPConnectionRefused.

Error code for the exception.

property ReplyErrorCode: Integer;

ReplyErrorCode is the error code for the exception and can be used for testing selectively to certain errors in your program.

Some protocols such as IMAP4 and POP3 do not use numerical error number codes. In such cases, we define constant values in the classes unit, and override the GetResponse method to parse those replies and return the constants. When this is done, you use the constants as if they were numerical values. Examples are the following:

• TIdPOP3 -

• wsOk - the operation succeeded

• wsErr - the operation failed

TIdIMAP4

• wsOk - the operation succeeded

• wsNo - the operation failed

• wsBad - bad command

Constructor for the exception.

constructor CreateError(const AErrCode: Integer; const AReplyMessage: string); virtual; reintroduce;

Error number form the peer.

Error reply from the peer.

CreateError is the constructor for the exception, and creates a EIdProtocolReplyError exception which takes the following parameters:

• asReplyMessage - text reply from a peer.

• anErrCode - error code from the peer.
