Detailed Description

A representation of an operation's outcome.

Constructor & Destructor Documentation

kudu::Status::Status ( const Status &  s )

inline

Copy the specified status.

Parameters

[in]

s

The status object to copy from.

Member Function Documentation

Status kudu::Status::CloneAndAppend

(

const Slice &

msg

)

const

Clone the object and add the specified suffix to the clone's message.

Parameters

[in]

msg

The message to append.

Returns

A new Status object with the same state plus an additional trailing message.

Status kudu::Status::CloneAndPrepend

(

const Slice &

msg

)

const

Clone the object and add the specified prefix to the clone's message.

Parameters

[in]

msg

The message to prepend.

Returns

A new Status object with the same state plus an additional leading message.

std::string kudu::Status::CodeAsString

(

)

const

Returns

A string representation of the status code, without the message text or POSIX code information.

bool kudu::Status::IsAborted ( ) const

inline

Returns

true iff the status indicates an Aborted error.

bool kudu::Status::IsAlreadyPresent ( ) const

inline

Returns

true iff the status indicates an AlreadyPresent error.

bool kudu::Status::IsConfigurationError ( ) const

inline

Returns

true iff the status indicates ConfigurationError.

bool kudu::Status::IsCorruption ( ) const

inline

Returns

true iff the status indicates a Corruption error.

bool kudu::Status::IsEndOfFile ( ) const

inline

Returns

true iff the status indicates end of file.

bool kudu::Status::IsIllegalState ( ) const

inline

Returns

true iff the status indicates an IllegalState error.

bool kudu::Status::IsIncomplete ( ) const

inline

Returns

true iff the status indicates Incomplete.

bool kudu::Status::IsInvalidArgument ( ) const

inline

Returns

true iff the status indicates an InvalidArgument error.

bool kudu::Status::IsIOError ( ) const

inline

Returns

true iff the status indicates an IOError.

bool kudu::Status::IsNetworkError ( ) const

inline

Returns

true iff the status indicates a NetworkError.

bool kudu::Status::IsNotAuthorized ( ) const

inline

Returns

true iff the status indicates a NotAuthorized error.

bool kudu::Status::IsNotFound ( ) const

inline

Returns

true iff the status indicates a NotFound error.

bool kudu::Status::IsNotSupported ( ) const

inline

Returns

true iff the status indicates a NotSupported error.

bool kudu::Status::IsRemoteError ( ) const

inline

Returns

true iff the status indicates a RemoteError.

bool kudu::Status::IsRuntimeError ( ) const

inline

Returns

true iff the status indicates a RuntimeError.

bool kudu::Status::IsServiceUnavailable ( ) const

inline

Returns

true iff the status indicates ServiceUnavailable.

bool kudu::Status::IsTimedOut ( ) const

inline

Returns

true iff the status indicates TimedOut.

bool kudu::Status::IsUninitialized ( ) const

inline

Returns

true iff the status indicates Uninitialized.

size_t kudu::Status::memory_footprint_excluding_this

(

)

const

Returns

The memory usage of this object without the object itself. Should be used when embedded inside another object.

size_t kudu::Status::memory_footprint_including_this

(

)

const

Returns

The memory usage of this object including the object itself. Should be used when allocated on the heap.

Slice kudu::Status::message

(

)

const

This is similar to ToString, except that it does not include the stringified error code or POSIX code.

Note

The returned Slice is only valid as long as this Status object remains live and unchanged.

Returns

The message portion of the Status. For OK statuses, this returns an empty string.

static Status kudu::Status::OK ( )

inlinestatic

Returns

A success status.

bool kudu::Status::ok ( ) const

inline

Returns

true iff the status indicates success.

void kudu::Status::operator= ( const Status &  s )

inline

Assign the specified status.

Parameters

[in]

s

The status object to assign from.

int16_t kudu::Status::posix_code

(

)

const

Returns

The POSIX code associated with this Status object, or -1 if there is none.

std::string kudu::Status::ToString

(

)

const

Returns

A string representation of this status suitable for printing. Returns the string "OK" for success.
