Class TBufferedOutputStream (unit SuperStream)

Inherits from

TStreamAdapter

The buffered output stream adapter can accelerate the use of underlying streams. Note that you can only write sequentially to this stream; reading or seeking will throw an exception.

Constructors


constructor Create(targetStream : TStream; bufSize : Integer; Owned : Boolean);



Functions

destructor Destroy; override;

Destroy a stream adapter.

function Read(var Buffer; Count: Longint): Longint; override;

Read count bytes into buffer.

function Seek(Offset: Longint; Origin: Word): Longint; override;

Move to a given position in the stream.

function Write(const Buffer; Count: Longint): Longint; override;

write count bytes to the stream.

Constructors


constructor Create(targetStream : TStream; bufSize : Integer; Owned : Boolean);


Functions


destructor Destroy; override;

Destroy a stream adapter. Will also destroy the target stream if the owned flag is set true.


function Read(var Buffer; Count: Longint): Longint; override;

ParameterDescription
bufferVariable to read bytes into.
countNumber of bytes to read.

Read count bytes into buffer. This is an override of the standard stream function.


function Seek(Offset: Longint; Origin: Word): Longint; override;

ParameterDescription
offsetThe position to move to.
originWhere to move: Can be soFromBeginning, soFromCurrent, or soFromEnd.

Move to a given position in the stream.


function Write(const Buffer; Count: Longint): Longint; override;

ParameterDescription
bufferVariable to write to the stream.
countNumber of bytes to write.

write count bytes to the stream. This is an override of the standard stream function.
