Detailed Description

All known error codes arising from XRL dispatches. These include underlying transport, transport location, and invocation failures.

This class can be sub-classed to provide a sub-set of the known errors, and also to append domain specific errors.

const XrlError&  OKAY ()

OKAY

[static]

The value that should be returned by functions whose execution completed normally.

const XrlError&  BAD_ARGS ()

BAD_ARGS

[static]

The value that should be returned when the arguments in an XRL do not match what the receiver expected.

const XrlError&  COMMAND_FAILED ()

COMMAND_FAILED

[static]

The value that should be returned when the command cannot be executed by Xrl Target.

const XrlError&  NO_FINDER ()

NO_FINDER

[static]

The Xrl Finder process is not running or not ready to resolve Xrl target names

const XrlError&  RESOLVE_FAILED ()

RESOLVE_FAILED

[static]

Returned when an XRL cannot be dispatched because the target name is not registered in the system.

const XrlError&  NO_SUCH_METHOD ()

NO_SUCH_METHOD

[static]

Returned when the method within the XRL is not recognized by the receiver.

const XrlError&  SEND_FAILED ()

SEND_FAILED

[static]

Returned when the underlying XRL transport mechanism fails.

const XrlError&  REPLY_TIMED_OUT ()

REPLY_TIMED_OUT

[static]

Returned when the reply is not returned within the timeout period of the underlying transport mechanism.

const XrlError&  SEND_FAILED_TRANSIENT ()

SEND_FAILED_TRANSIENT

[static]

Returned when the underlying XRL transport mechanism fails.

const XrlError&  INTERNAL_ERROR ()

INTERNAL_ERROR

[static]

An error has occurred within the XRL system. This is usually a sign of an implementation issue. This error replaces no longer existent errors of CORRUPT_XRL, CORRUPT_XRL_RESPONSE, and BAD_PROTOCOL_VERSION. The note associated with the error should contain more information.

XrlErrorCode  error_code ()

error_code

[const]

Returns: the unique identifer number associated with error.

const char*  error_msg ()

error_msg

[const]

Returns: string containing textual description of error.

const string&  note ()

note

[const]

Returns: string containing user annotation about source of error (if set).

inline string  str ()

str

[const]

Returns: string containing error_code(), error_msg(), and note().

bool  known_code (uint32_t code)

known_code

[static]

Returns: true if error_code corresponds to known error.

 XrlError ()

XrlError

 XrlError (XrlErrorCode error_code, const string& note = "")

XrlError

 XrlError (const XrlError& xe)

XrlError

 XrlError (const XrlErrlet& x, const string& note = "")

XrlError

 XrlError (const XrlErrlet*)

XrlError

const XrlErrlet* _errlet

_errlet

[protected]

string _note

_note
